meshing of a compound volume in GMSH
1 Attachment(s)
Hi there,
Could anybody please tell me why gmsh isn't creating any mesh for the physical volume 300 in my attached .geo file. 300 is a compound volume consisting 2 other volumes 107 and 109 into it and sharing a common surface 84. Regards Shawn |
Hi,
I think attached geo file is somehow broken as there is no points inside, here is Gmsh output: Code:

Hi alexeym,
I don't know why this has broken. However, I have attached the file again. Thanks and regards |
Hi,
Not quite sure if I correctly understood the geometry in the geo-file but it seems that you are trying to mesh overlapping volumes. AFAIK Gmsh can not do this. |
Hi alexeym,
Thank you so much for your reply. I have got the solution.Actually, it was about the embedded surfaces. Volume 200 is embedded into volume 300. Also it is sharing one of the surface of volume 300. That's why when we will define volume 300 we have to count all the surfaces of volume 200 into the surface loop of 300 except the one which is sharing the common surface of 300. Since, volume 200 is not totally inside the volume 300 we have to skip the surface loop of volume 200 into the volume 300 definition. Something like: Surface Loop for volume 200 : 200 = {1, 2, 3, 4, 5, 6}; Volume(200) = {200}; Surface 6 is sharing the surface 9 of volume 300. Hence, Surface Loop for volume 300: 300 = {7, 8, 9, 10, 11, 12, 13, 1, 2, 3, 4, 5}; Volume(300) = {300}; Then it will create mesh also for volume 300. |
