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

Re: WhitneyAVSolver unphysical B field when currents "close" to steel
Hi
Great! You almost had me worried. Maybe you could share the final outcome at the elmer-elmag repo.

Re: WhitneyAVSolver unphysical B field when currents "close" to steel
Hi, Ok, maybe the Jfix potential has a support that extends to the steel. On the other hand you cannot have a solution to the problem unless the divergence of current density is very closely zero. The alternative is to use elemental coil current in CoilSolver and request the "Fix Input Current ...

Re: WhitneyAVSolver unphysical B field when currents "close" to steel
Hi Do you have a reference solution? Last year around this time we looked at an even more simple case that intuitively didn't make sense. It was a case of cocentric cylinders with a jump in reluctivity. In the end we could find no problem in Elmer. We compared to an analytical model where it was eas...

Re: Unable to open .vtu file after Electrostatics tutorial
Hi, Just a note: the ascii output seems to be unaffected by the bug. So setting "Ascii Output = True" in ResultOutputSolver may save the day for some users. If you face this bug and want to open binary files you should revert to old "expat" library, or install paraview 5.12 with ...

Re: Unable to open .vtu file after Electrostatics tutorial
Hi Thanx for confirming that this is the issue! It is really annoying that an automatic update breaks a code and reverting to previous version of "expat" library is not straight-forward. It is natural to assume that the culprint would be Elmer - as it usually is - but in this is not at all...

Re: Unable to open .vtu file after Electrostatics tutorial
Hi No, the bug seems to have rolled to me also today. I locally work on a Ubuntu22 virtual machine and there last update in /var/log/apt/history.log is: Start-Date: 2024-03-18 10:16:54 Commandline: /usr/bin/unattended-upgrade Upgrade: libexpat1:amd64 (2.4.7-1ubuntu0.2, 2.4.7-1ubuntu0.3), libexpat1-d...

Re: Acoustic waves propagation in a solid body
Hi,
These are very different wave lengths. Acoustic ultrasonic ~1.0e-2 m and X rays 1e-9 m. So you can indeed study some realistic specimen with acoustic waves but with x rays not. Even if you had a small enough specimen you should consider then the molecular stucture as well.

Re: Unable to open .vtu file after Electrostatics tutorial
Hi This is strange. Nothing has changed in this fore ages. My colleague also had also similar issues with Paraview on Friday. Looks alot like this thread: https://discourse.paraview.org/t/i-cannot-read-a-vtp-file-i-could-open-yesterday-can-someone-try-to-open-it/13938/20 In fact, it does not open fo...

Re: export stiffness matrix without starting simulation
Hi, If the solver is never executed there will unfortunately be no stiffness matrix. You could however, try this keyword in Solver section: Linear System Solver Disabled = Logical True There might be other ways, like setting linear system iterations to zero etc. but this one should be clean. Codewis...
