Unable to start solver

Post by tanus »

Hello everyone!

I'm a new user of the Elmer and ElmerGUI, but I'm not being able to use it properly because of an error when trying to run the solver.

I've installed the Elmer software in my Ubuntu 22.04, I think everything is alright. But running the test of the tutorial:

Code: Select all

$ ctest -j4
there are 10 functions that fails

Code: Select all

81:ContractElasticCube
82:ContractElasticCube2
188:FrictionElasticCube
263:MeshSplitLevelset2d
415:Shell_with_Solid_BenchmarkCase1b
421:ShoeboxFsiStatic
423:ShoeboxFsiStaticShell
478:TwelveSolvers2D
519:circuits2D_transient_stranded
545:elmer_earth_2d_2layer
At first, I thought these wouldn't be that important, and maybe they really aren't. But running the Example 1, following the step-by-step of the Elmer FEM Webinar youtube video, for some reason when I try to start solver, the ElmerGUI doesn't open a solver window, and the terminal prints

Code: Select all

Solver emitted signal: QProcess::ProcessState: 1
Solver emitted signal: QProcess::ProcessState: 0
Solver emitted error signal: 0
Unable to start solver
The only big difference from the tutorial I've done was using the Gmsh to generate the mesh from the step file, because there were some posts of people not being able to run the Elmer mesh solver and saying to use an external software.

So, can someone help me to fix this problem?

Have you seen Chapter 12 of this document?
