Re: Cantilever Beam - Theory vs Elmer results

Anjali, Nice question for benchmarking Elmer simulations. What Matthias has said is correct. Elmer, through FEM, solves the equations for all the mesh elements, and then integrates them to give the integrated solution over the volume. The size of mesh element has effect on the simulation results in ...

Re: 2D magnet simulation - unphysical results

Hi, Any expert dealing with gmsh + ElmerSolver can reply you on these things. I am an user of Salome + ElmerSolver . In Salome, I use techniques such as submesh (to increase mesh density on certain parts), grouping Mesh of faces or edges, partitioning mesh, different type of mesh elements (quadrilat...

Re: Solving solid mechanics problems with material plasticity

I need to mention that we just changed in the devel branch the way how a user-defined UMAT subroutine can be included, so my previous instructions are not any more fully working. The main objective was to ease the compilation by removing the user's need to compile the whole solver of Elmer when int...

Re: statcurrent benchmark problem

Hi Steve, How about putting a neumann boundary condition at inlet (current density=1.00) and a dirichlet boundary condition (e.g. ground voltage , potential =0) at the outlet? For laplacian of potential, an inlet current of 1 means , outlet of 1 , owing to the principle of continuity of charge. Plea...

Re: adding youngs modulus as a function of stress

Dear Kevin,
Thanks for your wonderful examples of testing youngs modulus as a function of variables.

Yours Sincerely,

Re: ElmerSolver input file

How do I make the two solvers interact such that the output obtained from the CoilSolver is used as input for the MGDynamicsCalc solver? Ajay, Are you talking of hierarchical coupling from CoilSolver to MGDynamicsCalc solver? http://www.elmerfem.org/forum/viewtopic.php?f=3&t=4351&hilit=hierarchical...

Re: adding youngs modulus as a function of stress

Hi, How about the concept of exporting stress as variable from the stress solver (with default displacement variable), and then defining young's modulus as a function of stress in Materials section. Please find how total flux and total area are exported as variables from Advection-Diffusion(concentr...
