Hi all, When I was trying to create a mesh in Gmsh, while defining a cube, it automatically added a surface label that I already had, which is also in the
Surface Loop(29) = {167, 169, 170, 171,176,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25}; segment, it added surface 177, which is the same as my surface 25. When drawing the 3D mesh, the following errors occurred:
“Error: Invalid boundary mesh (overlapping facets) on surface 25 surface 177”
“Error: No elements in volume 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33”.
Why is this happening? Any small suggestions would be greatly appreciated.
