Elmer Discussion Forum

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...

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?

Loading ElmerGUI in the Elmer Virtual Machine that is built on Ubuntu 20 shows the following About screen. Open Cascade has been successfully compiled into ElmerGUI in the provided Elmer binary, at least in Ubuntu 20. Which version of Ubuntu do you run?

Hello,

Attached is a modified sif file, adding a slowly increasing load over time. This improves the behavior somewhat, up until the solver stops early.

Hello, Which version of Linux are you using? When you start ElmerGUI, click on Help, About. The About screen will show which options have been compiled into ElmerGUI. For example, this is the About screen from Windows 10 version of ElmerGUI. about-2.png This version can open the stp file from the Te...

Search elmerfem\fem\tests\*.sif for

Here is an alternate example, this time using elmergrid as the mesh generator.

Hello, Looking at the end of the solver log, where the heat solver doesn't converge, these rows appear: IterSolve: Linear iteration did not converge to tolerance ComputeChange: NS (ITER=2) (NRM,RELC): ( 0.38565092E+37 1.9979994 ) :: heat equation HeatSolve: iter: 2 Assembly: (s) 0.14 0.28 HeatSolve:...

I'd say that is a very good guess...

See attached modified sif file.

Attached is another example. Apply a load on the cantilever beam, StressSolver calculates the strain, then StatElecSolver uses the strain to calculate electrical potential.
