Salome: Elmer-plugin available

Postby RaJa » 22 Mar 2017, 14:43


The Elmer-plugin (incl. ElmerGrid mesh export and sif-file generator) for the Salome CAD/Mesh platform has reached Beta status. A big thanks goes to Matthias (mzenker).
It can be downloaded here:

A small demo can be found here:

What is it good for?
The plugin mimics the ElmerGui in the context of the Salome platform. It provides the same functionality as the "Model"-menu in the ElmerGui, allowing the definition of equations, material, boundary and body properties as well as simulation related parameters like time stepping, output file, etc.
Additionally, it provides a function that allows writing the settings into a sif-file that can be used as input for the ElmerSolver. Also, the Solver can be started from Salome. Finally, a once created sif-file can be used as input for the plugin to automatically setup a simulation.

Why not using ElmerGui?
We wanted to have everything in one single tool, since Salome already offers meshing and analysis in paraview. Building an interface to the Elmer-solver was kind of consequential.

How does it work?
When in the meshing module of Salome, the Elmer functionality can be accessed via the 'Tools'-menu: Tools->Plugins->Elmer. It contains a control window that can be activated and which provides faster access to the Elmer-functions.

Parallel runs of a simulation are currently supported only on Windows.
Important 1: Bodies and faces that shall be used for a simulation have to have a unique name without any blanks (e.g. "Face 1" has to be "Face1). Ideally, these names are definied via the group-function of Salome. The plugin uses the 'Use Mesh Names'-options by default and ElmerGrid crops the names at the first occurence of a blank.
Important 2: The current version also supports Salome 8.2.

There might be some issues with configurations we have not tested. Everything else is running stable.

Status as of Aug. 2017
We have refurbished the interface to Elmer: Everything is done via the floating control window. No cumbersome interaction via the Tools-menu anymore. Additionally, you can now set whether to use Parallel- or Single-Processing - just like in the ElmerGui.
There are also ideas about a convergence plot and a better integration in Salome.

I downloaded the content from the link provided as zip file. Unzipped and put he unzipped folder ElmerSalomeModule-master containing one folder (ElmerSalome) and two files (README and in D:\SALOME-7.8.0-WIN64\SALOME-7.8.0-WIN64\MODULES\GUI\RELEASE\GUI_INSTALL\share\salome\plugins\gui and then added the system variable SALOME_PLUGINS_PATH with above path on my win 7.

On my salome 7.8.0 in the Mesh module, when I go to Tool > plugin > I do not find elmer.

Could please help?

If you use the default directory then you do not have to add the system variable. So you may delete the entry. It could be possible that Salome gets confused by that. Additionally, you can check the terminal windows that appears when starting Salome for error messages. Sometimes the module is not loaded, because something went wrong during initialization.

And finally, as you use Windows, you can check
  • delete the current copies of the plugin again
  • go into the Windows explorer and enter %userprofile% into the address bar
  • navigate to the folder .config/salome
  • if not already existing, create a folder plugins
  • put the files from the zip-file there
This is the way I use the plugin, because it is much easer to find and does not require any settings in the system.

Report back, if you still have trouble.

I created a folder in .config\salome as Plugins and pasted one folder and two files as stated in my previous mail.

These are the messages I got

Thanks for the reply. There is an error during import and I have already checked the source and fixed it (hopefully).

Please download a new copy of the module and paste it in the directory. I have tested the new version on my machine and the module appears correctly.

Hi all,

the plugin has been updated - see Rainer's edit to the starting post. Now that most of the ElmerGUI functionaility is implemented, we encourage all Salomé+Elmer users to use the plugin and give us feedback about success, bugs and wishes for improvements!
