Dear Chen,
The command for compiling User developed solvers or subroutines is given in Chapter 2 (Section 2.2 )of Elmer Programmers Tutorial
(http://www.nic.funet.fi/pub/sci/physics ... torial.pdf).


Yours Sincerely,

Juris, I would say it is difficult to get convergent solutions for such a low value of viscosity for transient simulations (asssuming the original kinematic viscosity magnitude in the order of 10^{-7} supplied into the N-S equation is interpreted as dynamic viscosity by ElmerSolver ). In your case y...

The assumption of plane stress condition enables the dimensionality reduction for a simulation in 3D , and for a 3D simulation , the stress at a point can be represented by a 2D matrix for plane stress assumption.

Hi,
Since beginning I have been using Salome software for constructing mesh, and had never been through this problem.
It is nice to know that ElmerGrid has interface to convert externally created mesh into ElmerSolver compatible mesh.

Yours Sincerely,

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 ...

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...

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...

Dear Sabrina, LoadMesh: Base mesh name: ./point_charge Is your meshfile name point_charge? Header CHECK KEYWORDS Warn Mesh DB "."
