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...

Re: PMSM Simulation Symmetric vs Full Model
Hi Felix, The factor 1/3 comes simply from the fact that Elmer reports the torque of the mesh you see. So if you model 1/3 of the machine you will also get 1/3 of the results. I know there might be different conventions here. Ultimately this goes back to the history how it was first implemented. We ...

Hi
Did you look at test case ShoeboxFsiEigen2D? Just needs 3 instead of 2 dofs for displacement.

Re: Unexpected value for 'n' in UDF
Hi, I think there indeed is a "LIST_TYPE_CONSTANT_SCALAR_PROC" API for UDF (Lists.F90 line 5401) as opposed to "LIST_TYPE_VARIABLE_SCALAR" that is usually used. But I think that the parameters it expects are x, y, z coordinates - not the node number. Almost all UDF's floating aro...

Re: Solver connections question
Hi drmike, You might take use of the "DataToFieldSolver". Also the particle machinery has internal operation that also does sharing of particle properties to the nodes. The DataToFieldSolver allows solution by FEM and therefore you can add diffusion etc. for a smoother field. The particle ...

Re: Unexpected value for 'n' in UDF
Hi
Could you give pointer to "ELMER guide to FRM". I haven't seen such a book.
I'm pretty sure the function API works ok. Probably there is something wrong how it is called. But hard to say without seeing the actual code.
