Anexo C. Código fuente
A continuación se inserta el código fuente para el punzón de diámetro 20 mm. No se
incluyen para todos los punzones, debido a su extensión y a la poca información aportada, ya que es
prácticamente el mismo código fuente pero retocando parámetros en el apartado de creación de la
malla.
