I am dealing with the meshing of a combustion chamber in salome. Basically the chamber is just like a rectangular box in which air and fuel enter through a hole made in one of the faces and start reacting. I would like to carry a refinement of the mesh in the flame zone of the combustion chamber. Therefore, I would like to find a tool allowing me to design a geometrical box (like a cube or a rectangle) in which the 3D mesh must be refined. However, I dont find any tool allowing me to do that in the mesh module.
I have thought of modifying the geometry to reach my goal but I guess there might be some easier way directely in the mesh module of Salome to do such a basic thing ?
Would you have any ideas to perform such an operation ?
I think it’s necessary to modify the geometry to indicate the mesh refinement zone.
To do this, we need to create a circle (or other geometric shape) encompassing the hole and the desired refinement zone, then partition the original geometry.
The next step is to create a refinement group:
Create a face group
Create an edge group with the edges of the refinement zone.
Then, in both cases, you mesh with the NETGEN-2D-1D algorithm. There are also two possibilities:
Create a sub-mesh (face/edge), then enter a mesh/edge size smaller than that given for the global mesh.
Use the local sizes tab, then fill in the face/edge group, specifying a smaller size than that given for the global mesh.
