The 27 node quad is rather seldomly used that maybe there is some inconsistency in the treatment of the boundary indexes. Should not happen. You might upload the files & procedure as a bug report here in the forum / or github issue.

Re: Parallel grid seg fault
Hi,
Does it work for linear elements? It tries to identify the parent of the boundary element and obviously fails. The parent is found by matching indexes.
Which code has written the initial mesh.* files?

Re: Filled rectangular wave guide (VectorHelmholtz)
Hi
This is not a warning: You just have the code rather verbose and it tells you that "variable 2" was given type based on the keyword "variable 1" that is named in the keyword database. We could make this even lower priority.

Re: electrodynamic forces on busbars
Hi Sorry, I was reading hastily. So if you want to really solve the displacements also you should apply the nodal forces directly for the elasticity solver. Here conforming mesh is assumed. For example see, https://github.com/ElmerCSC/elmer-elmag/blob/main/CoilOnIronCore/case.sif The key lines are D...

Re: electrodynamic forces on busbars
Hi The way to proceed is indeed to 1) Use AVSolver to solver for electric/magnetic fields 2) Use CalcFields solver to compute nodal forces 3) Some up nodal forces and moments for each piece. Now 1) and 2) are shown in many test cases (as that of Kevin in force.sif). The step 3) is a minor technicali...

Re: Coupled Fluid-Structure Eigen Analysis
Hi Kevin,
The HelmholtzStructure cases are hierarchical: structure -> acoustics. The FsiShoebox* cases are strongle coupled: structure <-> acoustics.

Re: Toy hierarchical problem
Hi, In electromagnetics some fields are really discontinuous so when you try to project them to nodes violence may be performed if there is a jump in material parameter values. That's why options are given to either create a nodal, cell, or discontinuous galerkin type of field. All have their merits...

Re: Coupled Fluid-Structure Eigen Analysis
Hi Interesting discussions here. I am travelling so cannot spent time on this now. However, I can confirm that some real-world benchmarks have been solved a few years ago. These test cases are reflections of that work which itself was not made public. There should be clear effect of density. So that...

Re: MgDyn2D and high-order element
Hi, Paraview (VTU files) can only understand nodal data and cell data. When you have discontinous field that has different values at each node which one to use? The default is to use cell data which only can be constant within each element. If you want discontinous and not constant you have to repli...
