internal boundaries in gmsh
Posted: 31 Mar 2022, 13:50
Hi,
I am trying to make a simple heat tranfer analysis similar to the intrusion in tutorial 3. I want to calculate propagation of heatwaves from surface. (left) I made "1D" mesh, but with regresive node density to the right by spliting the body in gmsh
The problem i that there are now boundaries inside the body (although in gmsh they are se to be elementary entities). If I uderstood it properly, the boundaries will be set to heatflux = 0 if i leave them empty so it would mess up the results completly.
Is there any other way to make regresive node spacing?
Thanks for the answer
