I think if you do not give a reference norm, no check is made. and no file is created.

You are supposed to know the reference norm when you set up a test case. Consistency testing of solvers Each solver may be tested for consistency. The way the testing is performed is that it is assumed that the correct solution will have a predefined norm. After the simulation has been carried out t...

That is correct.

I ran the 0.1x0.01x1.0 in calculix, another open source fea tool. Using non-linear geometry option. It also calculated 0.088 same as ElastcSolver

"With this definition we say that the Young's modulus is constant, regardless of stress and strains. Is this correct? Are you saying that the ElasticSolver decides by its own that beyond a certain strain the material is no longer linear? Moreover, beyond the yield strength, in typical material...

If you run
ElmerGrid 2 2 MESH -autoclean
it will open in ElmerGUI
but it renumbers the BCs

The ElmerSolver should run with the mesh as is.

I thought they were two independent bodies connected by springs, but apparently they share nodes at the boundary? That is a different problem than I thought.

I thought perhaps it was due to rigid body modes, ElasticSolve and StressSolve so not much like rigid body modes in a static solution. So I added some constraints to take out rigid body motion without impacting the results. ElasticSolve converged much faster, but still arrived at 0.0044 answer. I at...

I ran it and received the same error, not seen that error before floodfill is a programming function to fill an array typically by area. It must have something to do with the BCs These BCs do not throw the error Boundary Condition 1 Target Boundaries(3) = 4 5 6 Name = "cube_4_faces" AV {e}...
