Elmer on Windows

Post by havsula » 13 Jan 2015, 14:47

Hello
I am planning to start using Elemer on Windows. But what is best way to use Elemer on Windows.
Which free cad tool should I use to make drawings to import into Elemer?

Hi,

there is a Windoze installer for Elmer.
You can use FreeCAD and gmsh for drawing and meshing, or Salomé for both. It's mostly a question of taste.

HTH,

It would have been really nice if Elmer included a simple cad tool (like Lisa which is a very cheap fem package) so that I do not need to make the drawing in another tool. I always prefer to do everything in the same program. But Elmer is free so I should not complain :D

Hi,

the Elmer team is not so big so they cannot do everything. They concentrate mostly on the solver which is rather powerful. For the rest, there are other tools made by other developper teams specialized in their area.
To complete the toolchain, you need a postprocessing tool. There you have the choice between ElmerPost (still working but not actively maintained), ParaView, VisIt (both for vtk output format, just change the extension of the post file to .vtu in the simulation section of the sif file) and gmsh.

Not really. The Elmer tutorials focus mostly on the FEM setup and solving, and do not show the use of external tools. They are a good starting point nevertheless. There is a lot of info spread around in the forum, including pre- and postprocessing topics, especially under "external tools".
Also the Elmer documentation, although not complete, does provide enough information to get very far in Elmer usage.

HTH,

Matthias
