Re: [SOLVED] Comparing with Comsol: many questions for you :D

you specified

Linear System Max Iterations = 500
Linear System Convergence Tolerance = 1.0e-10

which is the default. You con increase the iterations and/or decrease the convergence tolerance.

Convergence can also be improved by a finer mesh and/or higher order elements.

Re: [SOLVED] Comparing with Comsol: many questions for you :D

It means it has not converged to the criteria specified. It may be a good solution, but the math is not converged to the tolerances requested. It could also be a solution but not a correct one.

Re: GlaDS--ElmerICE

In general poor convergence can be due to too large a mesh size or too large a time step, or both.

Re: Pinned Boundary Countour

Rotation at the ends means the DOF are free, that is to say there is no boundary condition. If you want a beam pined at each end then you would only assign displacement boundary conditions on the ends. In the model manual Chapter 10 the boundary conditions are U and Theta, so a pinned beam would be ...

Re: 2D magnet simulation - unphysical results

You can use ElmerGrid to tranlsate mesh and merge nodes using -merge flag

However I much prefer Salome for meshing
