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 ...

Re: Coupled Fluid-Structure Eigen Analysis
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...

Re: Solver connections question
Maybe you could be more specific what you want to compute. Devil lies in the detail. -Peter
