import mesh with the edited *.mphtxt file

Please login with a confirmed email address before reporting spam

Hi, everyone:

I have a geometry mesh, and I knew the mesh node's coordinates: x, y, z in matlab workspace.
I want to import the mesh into COMSOL , and set the point whose coordinates were knew as the mesh nodes .
How to do this? Do I need to write a *.mphtxt file of the mesh? And how to edit the *.mphtxt files?

THanks for your help.


YH

Hi

do not forget that COMSOl does not "work with mesh" as older classical FEM programmes, but you define the physics on the geoemtrical domains and boundaries. So even if you improt a mesh, you need to define the corresponding domains and bondaries to get your physics attached correctly to the mesh elements. That is not often so easy ;)
But OK if you work on the same CAD domain in COMSOL and in matlab where you generate your mesh then it might work

Good luck
