Re: How to Obtain the Imaginary Part in Helmholtz Equation Simulations with Elmer
Hello, Regarding this statement in your previous post: According to ElmerTutorials.pdf, section 17 (17. Helmholtz – 2D – Acoustic Waves – Air in a Cavity), they refer to pressure wave in the x-direction and y-direction. As written, the tutorial could be misleading. The tutorial probably should say s...

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.
Rich.

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.

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