Hello,
thanks to your message, we have detected a bug in the code. We are working on solving it, and next version of the program to be released in the following weeks will have it fixed.
In the meantime, you can skip this if you delete the groups and assign them to the elements, once the mesh is done.
Kind regards,
ABEL
we have finally fixed the bug. The correction will be available in the next official and developer version of GiD16.
We will release that versions in a few weeks. I recommend you to be aware of our social networks and website to know when they will be released.
