I want to create a model that contains a simple square and a cylinder, but I’m having problems with the mesh, how can I solve this kind of problem, I hope you can give me some advice!
**cubit.cmd(‘reset’)
cubit.cmd(‘brick x 100 y 100 z 100’)
cubit.cmd(‘move vol 1 x 50 y 50 z -50’)
cubit.cmd(‘brick x 24 y 24 z 24’)
cubit.cmd(‘move volume 2 x 35 y 35 z -35’)
cubit.cmd(‘frustum z 24 radius 12 top 12’)
cubit.cmd(‘move vol 3 x 65 y 65 z -65’)
cubit.cmd(‘subtract volume 2 from volume 1 keep_tool’)
cubit.cmd(‘subtract volume 3 from volume 4 keep_tool’)
cubit.cmd(‘imprint all’)
cubit.cmd(‘merge all’)
Meshing the volumes
cubit.cmd(‘volume all size 1’)
cubit.cmd(‘mesh volume all’)**
For these geometries, you will have to webcut in order to mesh this as one solid mesh if that’s what you’re hoping for. Also, are you hoping for a hex/tet mesh for this?
yes, I would like to be a hexahedral mesh, and I have tried to make cuts, but unsuccessfully, due to the different way of dividing the upper and lower meshes, resulting in unsuccessful division of the middle layer.
Hi @sunflower,
just using one middle layer won’t work here. You need geometry that can be meshed with a sweep. You got here a many-to-many sweep attempt.
You could sweep surfaces to decompose the geometry. I just put the 3 volumes in blocks before doing the webcuts. This way you don’t need to handpick them together afterwards.
