Big Thanks for all the help.
I couldn’t have gotten ahead without advice I received on this forum.
Fred has been a saviour!
My question: Groups created in Salome appear as Bodies in a FEM called Elmer. For exmaple, like this…

How can I achieve the same for the geometry object shown?
Thanks & regards.
