Dear Christophe, I have one more question. After adding the periodic lines how can I have access to the periodicity information (master/slave) for the nodes of the mesh? Similar to what is found between $Periodic and $EndPeriodic in the msh file.
Once again thank you. -artur palha On Thu, Apr 26, 2018 at 3:06 PM Artur Palha <[email protected]> wrote: > Christophe, > > It works like a charm!
