1 SIMWARE E-LEARNING INTRODUCTION
Simware e-Learning is the Simware component that allows a LMS (Learning Management System) to act
as a tool consumer using Simware as a tool provider. This gives the capability of including Simware
Simulation Lessons as part of e-learning courses.
For using this component the next software should be installed and configured:
Simware Framework (v5.2.0 or later): The Simware Framework installer includes the next
components needed for developing and running a simulation: SimEngine, Modeler, ACS,
Scheduler, OpenSplice, Simware Control Library (SCL), Simware RecorderPlayer (needed for
tutorial mode of Simware lessons) and Simware LTI server. This installer includes also the
Simware e-Learning component.
LMS MOODLE (v2.7+ or later) Moodle is an LMS (e-Learning Management System) compatible
with LTI 1.1 specification. A basic Moodle setup covers installing Apache, MySQL and PHP 5.4+.
In the last chapter of this document is explained the recommended installation for Moodle, but
other installations or even other LTI v1.1 compatible LMS can be also used.
Simware e-Learning is a compound of several pieces of software. To get everything working as expected,
the next components should be installed and configured:
Moodle Activity Module "Simware": It is a set of PHP files that acts as the LTI Consumer part of
the communication. It is a Moodle plugin, thus it has to be installed on the same node as
Moodle. Each instance of this resource in each Moodle course includes some snippets to get
simulation started in SELC server and student’s system. Also you can submit the initial scenario
file (.xml) for the lesson.
Simware E-Learning Launch Control (SELC): It uses Simware LTI server acting as the LTI Provider
part of the LTI communication. It is the gateway between the simulation communications using
Ncware and the LTI messages with the LMS.
Each SELC process is only capable of running one simulation for one student at time. So you
must run several instances of SELC (with other port numbers) in the same node, or distributed
into several nodes. This is up to you and with your infrastructure.
Simulation lesson generator and templates: This includes the next tools and templates for
configuring any Simware simulation as a Simulation lesson:
o GradeLisener Generator: This tool generates, using the simulation datamodel, a library
that publish the e-learning interaction for communicate the grade and the ending
criteria of a simulation lesson.

o ModElearing Simulation Service: It is included a SimDeveloper module that has to be
tailored for each simulation and for each lesson for calculating the grade and the ending
criteria of a simulation lesson.
o Templates and wrapper: There are supplied a set of scripts and wraps for stating
specific OSPL domain and network settings for each lesson and for launching the
simulation applications in the same domain as the SELC.

2 INSTALLATION OF ACTIVITY MODULE (MOD_SIMWARE) FOR
MOODLE
The main requirement to install mod_simware is to have Moodle 2.7+ previously installed. In the last
chapter of this document, Section 4 Installation of LMS (Moodle), there is the recommended setup, but
you can use any other Moodle setup.
To install an activity module into Moodle, is just copying files under /mod/ folder on server. Type this on
a terminal, replacing the path to directory moodle-mod_simware and Moodle’s root accordingly.
$ sudo -u www-data mkdir -p /var/www/html/moodle/mod/simware
$ sudo -u www-data cp -arfv elearn/moodle-mod_simware /var/www/html/moodle/mod/simware
Just login to Moodle as an administrator using the web browser, and you will see a notifications page,
requesting you to upgrade the Moodle database in order to finish the install of the new plugins.
Click on «Upgrade Moodle database now» to do this.

USER GUIDE
2.1 RUNNING SELC SERVERS
To connect the Simware Activity Module installed in Moodle with the Simware Simulations, it is needed
to run a SELC server application.
This application translates the LTI messages sent by the LMS Activity Module to the next elements:
Messages for configuring the simulation (templates for ospl.xml, Simware configuration file and
scenario for the lessons).
Calls to the Simware Control Library (SCL). SELC applications use SCL for sending, to the Simware
Simulations, the Simware eHost Control Datamodel objects and interactions needed for:
o Load initial instances scenario files.
o Manage simulation state machine.
Additionally, the SELC translates the Simware simulation interaction of lesson ending criteria and
evaluation to a LTI message, which is sent to the LMS Activity Module. The SELC application has the next
shown options, which are explained by invoking it with --help.
$ /opt/Simware/simwareElearning/bin/simwelearn --help
Allowed options:

It is recommended to prepare a script, which launches of the SELC applications needed, taking into
account the configuration of the Simware Activity Module in Moodle, explained before in this
document. Both settings, the configured in Moodle and the one written in the script, should match.
The product is supplied with an example of this script with 3 instances of SELC for allowing 3
simultaneous lessons. This script is called "3instances.sh" and is located at
/opt/Simware/simwareElearn/bin.
2.2 CREATE A SIMWARE LESSON
In a LMS, each lesson should be part of a course. A course is a structured set of learning activities that
enrolled students must complete.
So, the previous step for creating a lesson is to create a course. These steps are independent of the use
of Simware:
1. Logged in as an Administrator (or any other role with course creation rights).
2. Go to the front page of your recent installation of Moodle (http://localhost/moodle) and click on
“Add a new course”. There are a lot of fields that you can set to customize the course
appearance and behavior.
3. Once logged in the course as a user with course edition rights (teacher, i.e.) you should enable
content editing by doing click over “Turn editing on”.
Once the course is created, the Simware lesson can be added to the course:
4. Click on “+ Add an activity or resource” to add a resource into that section of the course.
5. Choose Simware and click “Add”.
6. Fill in the Simware lesson’s details:
a. Simware lesson name. This is the title of the learning activity. It appears at the course
index and in the title of the page when running the exercise.
b. Description. Brief description area for explaining the student what to do. If you check
“Display description on course page”, then it is also shown at course index.
c. Type of lesson: There are two types of Simware Lesson:

i. Tutorial mode, the instructor records the whole exercise, and students replay it
to learn how to do it.
ii. Exam mode, the student has to do the exercise and get 0-10 points when the
ELEARNING module of the simulation computes and emits the evaluation
according to the lesson number.
d. Configuration of exercise > Scenario XML file: This is the Simware scenario file for the
initial conditions and parameters for each lesson.
e. Configuration of exercise > SRP config file name: This is the name of the file under
deployfolder/srp/configFiles/ which will be used for replaying the simulation. Only
needed for Tutorial mode Lessons.
f. Configuration of exercise > SRP session file name: It is the name of the session data file
(must be placed on deployfolder/srp/sessionFiles/). Only needed for Tutorial mode
Lessons.
g. Launch configuration: This section configures the LMS to run the simulation. This
configuration should match with the SELC server configuration.
2.2.1 Launch Configuration for SimShapes-eLearning
To configure a Simware lesson of type SimShapes, these are the recommended values for the fields:
Simulation deploy folder at Simware Server. This is the path where all of the folders and files
needed for running the simulation are placed. There should be located the files run.sh, launchenv.sh, ospl.template.xml and simulation.xml. The Simshapes example is, by default, installed at
/opt/Simware/simwareCore/examples/simshapes/bin/linux32/.
Script to run on Simware E-learning Launch Control server. This is a template for the script that
will be run at the SELC server. Those placeholders marked between "@@" are replaced with
correct values before the execution. The values depend on which particular SELC node/instance
is used each time.

2.3 RUN A SIMWARE LESSON
To run a Simware lesson from Moodle, click on its tittle at the course index page.
If there is no SELC available, Moodle displays an error message asking you to wait some time and retry.
Maybe, the list of URL is misconfigured in mod_simware settings, or maybe the system administrator
forgot to run the SELC services (by either launching the script "3instances.sh", run simwelearn manually,
or installing it as system service).
If everything was OK, the user will see a page with two options:
1. Download launcher client script. Click this if you are using Linux or Mac OS X. This link generates
a bash script file with the contents of the field Script to launch on student system in the launch
configuration of the simulation. The script generated contains any placeholders replaced with
suitable values. The downloaded file must be run on the client’s shell, double clicking over it or
in a shell: bash -x ~/Downloads/launch_simulation_XXXXXXX.sh. This script allows the
server to forward X11 to the client. Alternatively on Windows, run:
xming.exe -multiwindow -ac
2. Launch simulation on SELC. This link generates a server script by also replacing any placeholder
present in the contents of the field Script to run on Simware E-learning Launch Control server
from Simware lesson resource. Click on this, and you’ll go to the next step.
2.3.1 Completing the Exercise
The steps to complete the exercise are:
1. Play button: Scenario file is loaded, and then simulation begins its execution.
2. Do the exercise using the tools provided by the system for the lesson. These tools can be ACS to
send interactions, create or delete objects, or using other ways of interacting with the simulator.

3 ADAPT SIMWARE SIMULATION TO SIMWARE E-LEARNING
Any Simware simulation might be used as a lesson activity with Simware E-learning. Minimal changes
should be done to files for dealing with this.
We use along this section the SimShapes simulation as the example to adapt it for being used by
Simware E-learning.
The
folder
for
the
default
installation
of
SimShapes,
/opt/Simware/simwareCore/examples/simshapes/bin/linux32 will be used as the deploy simulation
folder for the configurations files and scritps.
3.1 SIMULATION MODULE MOD_ELEARNING
The simulation must include a module whose responsibilities are calculating the grade of the exercise
done by the student.
The module should publish a single interaction when the exercise has been completed (successfully or
not). Interaction type name must be “OrdenElearning”, with almost two parameters named:
evaluation — floating point number between 0-10 with the score.
reasonSimulationEnd — enum indicating the reason for ending the exercise. The value “1”
means that the exercise has been completed. Any other value means different ending
conditions.
The module can be configured at startup time, if scenario file includes a configuration parameter named
ParamElearning, with an enum attribute LessonNumber indicating lesson number type.
Refer to the document named “Design document of module mod_elearning" for further details about
how to develop this module.

3.2 MAIN SIMULATION CONFIG FILE (99.XML —> SIMULATION.XML)
In the SimShapes example, there is a file named 99.xml which is the Simware Simulation configuration
file for running on DDS Domain number 99. Simware E-learning is ready for running simulations for
multiple users simultaneously, so 99.xml must be renamed to simulation.xml to allow multiple DDS
domains in the way we are about to describe.
Moreover, the XML label <AppControlSIM id=”8”> must be duplicated as a new XML sibling section
named <AppControlSIM id=”88”>, but with one difference: emptying the section for parameter panels
<Object-Parameters>. That new section (88) will be used for ACS, if it is needed for performing the
lesson, while section 8 will be used for SELC.

3.4 START/STOP APPLICATIONS ALIASES (LAUNCH_ENV.SH)
We recommend writing a bash script with aliases to start and stop applications needed to run the
simulation on the server. Also, this script receives some variables to configure networking parameters to
allow multiple users (ospl domain, port numbers, and so on). This bash script also generates a “killer
script” with commands to kill everything if that was necessary. Example file “launch_env.sh” for
SimShapes is included in the release.
3.5 MAIN RUN SCRIPT (RUN.SH)
This script loads the alises defined in launch_env.sh configured with some parameters and it runs the
main function.
#!/bin/bash -x
export L_MOODLE_PID
source launch_env.sh "[email protected]"
if [[ -r run.args ]]; then
source run.args
fi
export L_PARENT_PID=$$
l_shapes
exit 0
You can test it isolated from Simware E-learning by running ./run.sh 98, for example.

3.6 LIBRARY FOR LISTENING THE GRADE (LIBGRADELISTENER.SO)
There is a folder named libgradelistener in the release of Simware E-learning which is a template to
build a library for listening the grade from mod_elarning and then it can be read by SELC in a way
independent from the datamodel.
Run the script ./configure_and_build.sh to configure, compile and install the libgradelistener.so file to
root directory. The script will ask you four questions:
1. The directory was Modeler+ has generated the files for datamodel library. Example:
root_directory_of_simulation_files/datamodel/.
2. The name of datamodel library binary (lib<name>.so); example: “simshapes-opensplice” to refer
the file “libsimshapes-opensplice.so”.
3. The name of the datamodel namespace. Example: “SimShapes”.
4. The directory where to put the output file, "libgradelistener.so". Example: deployfolder/lib

4 INSTALLATION OF LMS (MOODLE)
Simware E-learning makes use of a Learning Management System named Moodle. It is an open source
project, maintained by a community of developers around the world.
In this chapter we follow basic setup of Moodle on Ubuntu Desktop 12.04.5 LTS, 32 bit. To install it on
other platforms, or advanced setup configurations, please refer to the official installation
documentation (Moodle, 2014) at https://docs.moodle.org/en/Installing_Moodle.
We suppose in this instructions that there is a fresh install of the operating system.
4.1 SETTING-UP UBUNTU REPOSITORIES
Moodle 2.x needs a later version of the PHP engine that which is included in 12.04 LTS. To do this, type
the following code on a terminal emulator (if you are installing it on a further Ubuntu release which
includes php 5.5, this step is not necessary):
$ sudo add-apt-repository ppa:ondrej/php5
$ sudo apt-get update
4.2 SETTING UP LAMP ENVIRONMENT
Moodle works on a LAMP environment (Linux-Apache-MySQL-PHP). Although MySQL may be replaced
with PostgreSQL, we’ll install MySQL as recommended by the Moodle developers.
Moodle could work on Windows (WAMP) or Mac OS X (MAMP).

The following packages must be installed on your system as prerequisites (and their dependencies):
apache2
mysql-server (>= 5.5.20)
libapache2-mod-php5 (>= 5.5)
php5-mysql (>= 5.5.20)
php5-curl
php5-gd
php5-xmlrpc
php5-intl
During this process, MySQL will ask for a password of MySQL’s root user. It can be empty because only
local queries are allowed (by default).
After installing those, please type the following command on a terminal prompt:
$ sudo service apache2 restart
4.3 INSTALL MOODLE 2.7+ UNDER APACHE’S DOCUMENT ROOT
After that, you must download the latest binary stable release from Moodle’s official website:
https://download.moodle.org/releases/latest/
This
is
the
direct
link
for
the
Moodle
https://download.moodle.org/download.php/direct/stable27/moodle-latest-27.tgz
2.7
series:
To install Moodle inside Apache’s document root, for localhost, run the code below on a terminal
emulator, adjusting the path to moodle-latest-27.tgz file:
$ sudo chown www-data:www-data -Rfv /var/www/html
$ sudo -u www-data tar xzvf Downloads/moodle-latest-27.tgz -C /var/www/html

This way, Moodle will be accessible from http://localhost/moodle.
Moodle needs a storage area (a.k.a. moodledata). To create it at default path:
$ sudo mkdir -p /var/www/moodledata
$ sudo chown -Rfv www-data:www-data /var/www/moodledata
Next steps will create a MySQL database a user for usage by Moodle LMS, with password moodle:
$ mysqladmin -uroot create moodle
$ mysql -uroot moodle -e "grant all on moodle.* to moodle identified by 'moodle';"
4.3.1 Installation Wizard
After that, now we can continue the setup by hand on a firefox browser. Please use a proper domain
name (other than localhost) if you pretend to it being accesible from outside of the local server.
$ firefox http://localhost/moodle
Almost every step, it is enough to accept default values and click «Next».
