Dear Bruno, I did some modification according to your suggestion : ********************************************************
*Physical Volume("4") = {1};//+Physical Surface("0") = {4, 3, 2, 5, 1, 6};*
********************************************************
I add all external surfaces in one physical group and the volume in another
group. But the error message remains the same. I tried a few types of
grouping combinations, the error message did not change.
Best regards,
Yuesu
