"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}...

Solution with conforming mesh

You can use Salome to import the stp file which comes in as one solid, but use the explode command to show that it is really 13 different solids (or bodies) in Elmer. The goal would be to merge these 13 into one sold to obtain a conforming mesh, Or use the 13 to define mortar conditions. bodies.png

Mika is correct that the Large Deflection = False works in Elastic Solver when the UMAT subroutine is defined for the material.
Converges quickly to the desired answer regardless of number on non=linear iterations.

scanning in the case of elasticsolver is just a step solution where each step depends on the previous solution.
