Smooth Mesh in SALOME

Use of the platform
1

Hi,

In ANSYS ICEM, it’s possible to smoothen the mesh efficiently in stages by smoothing various element types separately. I am looking for a similar approach or workflow in SALOME that allows for effective mesh smoothing.

Could anyone suggest an efficient workflow or best practices for achieving this in SALOME?

Thanks in advance!

today there is no 3D smoothing only 2D in salome feature request. you might export the mesh smooth it outside with another tool and then import back the positions.

keep in mind that depending in which kind of meshing algorithm you are using there are parameters for 3D smoothing, netgen, gmsh for example.

Thanks Franco,

I have a feeling that a few elements are causing trouble in my simulation.
Since I am trying to shift the workflow from ICEM, I am trying to replicate the features as closely as possible.

Any suggestions on finding the mesh quality values and smoothing parameters for Netgen?

I don’t do much unstructured meshing I must say, I have been having good results by default with netgen, I always set the min and max sizes really close but this gives a large number of cells. But I don’t remember having too many smoothing parameters, isn’t there only the number of iterations for the smoothing? I would check gmsh if netgen is not giving the results you are looking for….
