Boundary conditions : periodicity

D 13 mai 2009    

In main.rpm file, one must define first the periodicity :

translation periodicity
 NAME  = (name)
 TRANSLATION = (vector)
rotation periodicity
 NAME  = (name)
 ROTATION_AXIS   = (vector)
 ROTATION_ANGLE  = (degree) or ROTATION_NUMBER = (n) (angle = 360/n)

One can then define one or several periodic connections with :

 FAMILY1     = (one   side mark)
 FAMILY2     = (other side mark)
 PERIODICITY = (name of block:periodicity)

Note that the periodicity defines a direction from FAMILY1 to FAMILY2.
