Re: Steady state convergence tolerance
Hi Roland, The convergence criterion is |u_i - u_j| < c*(|u_i|+|u_j|)/2, where c is the tolerance. For nonlinear system j refers to previous nonlinear iterate. For coupled system j refers to the solution of the previous time the coupled system visited the solver. Generally it may be a good idea that...

Re: How to get H20 and H27?
Hi 827 has probably not been used as much as 820. The ordering of the 20 nodes is the same, then then 6 face nodes are ordered in the order of the faces, and the last index is given for the center node. Also 409 is different from 408 just by the last center node. I think 827 in the logic requires so...

Re: Solver connections question
Maybe you could be more specific what you want to compute. Devil lies in the detail. -Peter

Additionally if you decleare variables you may use, for example:

Re: Elmer as a replacement for Ansys HFSS in superconducting quantum circuits
Hi Most transient models can also solve eigenmode problems. These are consistency tests for EM waves with two different formulations: elmeruser@elmer-VirtualBox:~/Source/elmerfem/fem/tests$ grep -i 'eigen anal' -r | grep wave EMWaveBoxHexasEigen/emwave.sif: Eigen Analysis = True mgdyn_wave_eigen/cas...

Re: Free-Free Beam Eigenvalue Test
Hi Just a note on something that could be confusing: If ResultOutputSolver (the one writing vtu files) is given the keywords "Eigen Analysis = Logical True" the numbering will reflect eigenvalues. Otherwise it will reflect timesteps (or steady state iteration steps) and specific naming sch...

Hi
Paraview has been broken by automated update of "expat" library on some platforms. Really annoying.

Re: Elmer WSL Debian 12 with Elmer Virtual Machine Scripts
Hi Masahiro,
Really great work you have done to bring Elmer into the Windows Subsystem! With the detailed instructions I'm sure many people will try this out.

Re: Building Elmer for Nixpkgs fails
Hi
Rather use the "devel" branch and let's see the complaints anew then.

Hi
Maybe you only save physical entities. Ask Gmsh to "save all".
