can you go inside the install folder and do

mkdir /lib/elmersolver

Great, thanks.

It would be nice to add, but at least a message to tell the user it is not supported would help cut down on confusion.

and if I add some damping to the 1D beam
Rayleigh Damping = Logical True
Rayleigh Damping Alpha = Real 100.2836
Rayleigh Damping Beta = Real 5.38E-5

I don't get any

I decided to go back to this damping test and repeat it using the 1d beam model and the initial displacement method

The 1D beam element results look reasonable

Nice work.

for trouble getting meshes to connect with each other across 3d boundaries, generally the coherence command right before meshing will resolve it.

It is a tough case to mesh. The aspect ratio is one thing. Typically you would go with 2D elements, and maybe that is a possibility. Will have to think about. Another problem is features features.PNG the bottom radii cause reentrant corners, very difficult to mesh locally in that area, if this is no...

I would not expect any damping unless you defined it in the material property section. It certainly looks like a damped response. The way you started it is interesting, with the initial displacement of the entire model 0.1 then with the boundary condition you bring back node 1 to zero. Elmer does no...

The default iterative solver generated by the gui usually has something like this Nonlinear System Convergence Tolerance = 1.0e-7 Nonlinear System Max Iterations = 20 Nonlinear System Newton After Iterations = 3 Nonlinear System Newton After Tolerance = 1.0e-3 Nonlinear System Relaxation Factor = 1 ...

I mis-understood the boundary conditions, I made current in the entire bottom surface. Very difficult to tell with how thin the part is. Scaling is OK, but I think it should be the same for every coordinate to avoid element distortion. If it is necessary to model Z at actual times 10000 , then model...
