Hi. I created ewfd model and tried to Compute, but I got this error message

"Either two periodic conditions are needed or a reference point needs to be added at the periodic port.

the destination boundary is missing or the destination is not selected.

-Function: Periodic condition 1 (pc1)"

Would you please tell me what that means and what to do. The above message is translated Japanese →English ,so it may not be correct.

Thanks in advance.

Periodic conditions require source and destination boundaries to be specified. The error message means that you did not do that properly/completely. I can't read the Japanese in your file and I don't have that module either, but I think (maybe?) you only have sources specified, without any destinations?

Thanks to your reply. it is original error messasege, "Two periodic conditions are needed or a reference point on the periodic port needs to be added. Failed to find destination boundaries or the destination selection is empty. - Feature: periodic condition 1 (pc1)"

and I upload English File.

I'm going to rethink the model again . Thanks in advance.
