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...

Re: Problem reading in netcdf file at higher resolution
Hi I added a few days ago some more output (with high "max output level") so you might get a better idea now what is going on. Generally memory issues may be difficult and if it happens in netcdf library it is hard to tell. In Elmer it is a good idea to always use and check the optional ST...

Re: VectorHelmholtzSolver and 2nd Order Elements
Hi
Elmer has 2nd order edge elements (Nedelec's 1st kind) invoked by "quadratic approximation = true".

Re: Elmer-elmag example throws error
Hi, can you solve anything with success? CUDA does not like DLL so that could be the culprint. However, in that case you should not be able to run most cases. There is something fishy since the code should be looking for "ProcName_bulk" and not just "_bulk". What is you setup and...

Re: impulse boundaries conditions
Hi I think forces are always in cartesian directions. What the code does is it assembles the equations in cartesian coordinates. Then it rotates the entries when glueing them into the global matrix. The Dirichlet BCs are then set in this global matrix and hence there the "normal-tangential disp...
