Boundary conditions : periodicity

D 13 mai 2009

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

translation periodicity

BLOCK:PERIODICITY

  NAME  = (name)

  TYPE  = TRANSLATION

  TRANSLATION = (vector)

ENDBLOCK

rotation periodicity

BLOCK:PERIODICITY

  NAME  = (name)

  TYPE  = ROTATION

  ROTATION_CENTER = (vector)

  ROTATION_AXIS   = (vector)

  ROTATION_ANGLE  = (degree) or ROTATION_NUMBER = (n) (angle = 360/n)

ENDBLOCK

One can then define one or several periodic connections with :

BLOCK:CONNECTION

  FAMILY1     = (one   side mark)

  FAMILY2     = (other side mark)

  TYPE        = PERIODIC

  PERIODICITY = (name of block:periodicity)

ENDBLOCK

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