Hi everyone,
I’m relatively new to the SALOME platform, but I find it very promising. I am preparing an OpenFOAM simulation of a hot room that is connected to the environment through an airlock (a forced warm air jet). The transition between the hot room and the environment has a rather complex geometry.
To handle this, I used the Gmsh 2D algorithm to mesh the complex base faces and then applied extrusion as the global algorithm. This allows me to generate a mostly hex-dominant mesh with some prisms.
Refinement in the extrusion direction works well. However, I would now like to locally refine the mesh in other directions (between x = 0 and x = 2) without globally refining the base face, as that would significantly increase the total cell count.
Maybe its even possible to define a volume where the cells are refined, to catch the expected flow better.
I am aware that refining the base face would propagate through the extrusion, but I am looking for a way to achieve local refinement in selected regions only, ideally while keeping a hex-dominant structure.
Is this possible in SALOME when using extrusion-based meshing, or are there recommended workarounds ?
Thanks in advance for your help.
