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 ...

Thanx! I added the fix to "devel" branch. -Peter

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.

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...

Maybe you could be more specific what you want to compute. Devil lies in the detail. -Peter

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...
