I have a 20 body geometry that was meshed in Salome and exported to Elmer as a UNV file. The mesh size is 546,750 elements which brings Elmer to a crawl on a Windows 7 quad core. Is there any control option in Elmer to reduce the fineness of the meshing? Is that something that should be taken care of in Salome? Currently I'm using whatever defaults are in each program.
Thanks,
Brian
Control of mesh size?
Re: Control of mesh size?
Hi Brian,
meshing fineness should be take care of by the mesher (i.e. Salomé) in the first place.
Yes, the GUI gets slow when the mesh is large.
You could create a coarser mesh, set up your case, and then replace the mesh by a finer one only when everything is set up, so you have the slowliness only in the last step. In that case, note the numbers of the boundaries since their assignment to boundary conditions gets lost when you change the mesh in ElmerGUI.
Or else keep the coarser mesh and use
(or higher) in the Simulation section (Free text field) to increase the mesh density.
HTH,
Matthias
