Hi Paul,
Could you provide some insight into this problem with the periodic bondary condition as described below? This error occurs when running genmap.
Thanks,
Michael

Hi,
I was able to solve this by removing the element face count column.
I now run into the following issue shown below. I was able to find the subroutine spec_bis_conn where this error occurs.
I believe this has to do with the periodic faces I have set up. My question is whether the periodic faces need to be continuous:
For example, the geometry is similar to fluid flow over a flat plate on both sides. The fluid is periodic, but separated by the solid
thickness (this is a Conj HT problem). Essentially there is a "gap" in the periodic fluid portion if you can imagine. I saw a note in
the routine that says something like "ensure that all graphs are connected", not sure if this is what it means. I tried making the fluid
periodic on only one side of the plate and it worked, however when I make the other side (bottom of the plate) periodic with itself
I get the following error. Any thoughts? Thanks - Michael M.
