Re: ElmerGrid "forgets" some names converting from gmsh

The attached archive includes bug.geo and four scripts. The scripts will run gmsh and output the msh file in both format 2 and format4, followed by ElmerGrid converting both msh files into elmer mesh format. ElmerGrid converts the gmsh format 2 msh file, retaining the duplicate boundaries. ElmerGrid...

Re: ElmerGrid "forgets" some names converting from gmsh

It makes sense for ElmerGrid to eliminate duplicate boundaries. On the other hand, to remove boundaries silently is not nice. It would be nice if ElmerGrid would output a message something like: Duplicate boundary 123 found, keeping first occurrence of boundary 122.

Just my two cents.

Re: IsosurfaceSolver

Hello,

ElmerGUI includes ElmerVTK under the 'Run' menu. ElmerVTK is able to create isosurface plots. Using your gmsh file, and increasing the radius from 0.65 to 12, ElmerVTK shows a nice plot of the potential isosurface, using clip of course. Does this help?

Re: IsosurfaceSolver

Hello, Since your gmsh model is in millimeters, one should add 'Coordinate Scaling = 0.001' to the Simulation section. Adding that command allows Isosurface solver to finish without a seg fault, but with a different warning message: WARNING:: IsosurfaceSolver: No potential elements found for isosurf...

Re: Parallel computation is failing to start (that's all the log says)

Using the same parallel ElmerGUI example, and mis-spelling 'ElmerSolver', gives this error message: ERROR: Error reported: failed to launch 'ElmerSolv0er_mpi.exe' on DESKTOP-D6N8F4T Error (2) The system cannot find the file specified. Another case, with ElmerSolver spelled properly and adding an inv...

Re: Parallel computation is failing to start (that's all the log says)

Hello,

I was able to duplicate the error. . All I did was take a working ElmerGUI parallel example, open parallel settings, and in the 'Executable' box, misspell 'mpiexec.exe', and then run.
Unable to start parallel solver

Hello,

A screenshot will help. Being able to duplicate your run is very helpful.

Re: Parallel computation is failing to start (that's all the log says)

Hello, It would help if you would post the command line entries that you used. A working example would be even more helpful. Elmer is very flexible, which also means lot's of little things can go wrong. If your model isn't proprietary, maybe you could post it on a file sharing location, such as gith...

Re: Can't run first tutorial on Linux because of meshing error

Hello,

There is a new version of the Elmer VM, based on Ubuntu 22. I downloaded and installed the VM, and checking the preinstalled binaries, I can confirm ElmerGUI was compiled with Open Cascade.

Is it possible the OP had issues with a launchpad version of the binaries?

Rich.
