Equation Electrostatics
Hi Elmer Team, I want to simulate the distribution of the current density on a body. So, I looked to the Elmer Tutorials and found the Tutorial 9. In this chapter, an equation Electrostatics Active on is named. In my Elmer download Elmer 6.0 of August, I haven't found the equation Electrostatics. - ...

avoid of Degenerate 3D Element
Hi Elmer team, in the last time I had very good simulations with Elmer, which lead to powerful results and presentations. But for getting still better, I have quite a problem. This are the Degenerate 3D Elements at ElmerGUI, when the Equations are to be solved. When I mesh the attached volume with t...

volume models in elmer post processor
hi elmer team, in elmer, I solved a navier-stokes equation with a flowing medium in a tube. therefore, the walls have the velocity value of zero. when I get into the elmer post processor, I only see these surfaces with the value zero in a surface model, but not the elements inside the tubes, which h...

calcaulation of a laminar / turbulent flow
hi elmer-team, I have quite a little problem. I bulit up in gmesh a simple tube with an inner diameter of 0.010m and a length of 1m. this tube is flowed through with a water. the flowing water has a defined velocity. by comparison with other calculations, elmer only gives comparable results when the...

defining of non-constant flow
Hi Elmer team, I have quite a little problem. I want to simulate a non-constant flow of a cooling medium in tubes of a body, which surfaces is heated by other bodies. In my model, there is a mid plate of aluminium, which is heated by heating dummy bodies at its both long sides. the heat source of th...

problem of maximum msh-file probably solved
hi elmer-team and all, last week I had a problem with elmer, that I could only handle msh-files with size of about 60MB, otherwise elmer crashed. now, I find the mistake. the point, elmer always crashed, was at copying the msh-file into the elmer project dir. when you load the msh-file out of the la...

how to define a constant flow of medium for cooling
hi elmer-team, I have a problem with a long, nearly quadratical aluminum body. at each of its long sides, there are bodies with a constant heat source. in the middle of this alu body, there are a few of holes in direction of its length for cooling the alu bodies and the two heat bodies with several ...

Re: maximum size of gmsh *.msh-file?
hello peter, thanks a lot for your quick answer. I tried to do so as a suggested. But there is always the same mistake, even at *.msh-files which are smaller than those, who I can directly transformed into an elmer project. elmer always crashes at the same moment. elmer founds edges on the boundary,...

quantity of materials
is there a correlation between the quantity of materials in an elmer project and its size with the solver convergence? I made an elmer project with 1 equation, 16 bodies, 4 materials and 1 boundary condition with 240 boundaries. the gmsh *.msh-file had a size of about 57MB. the solver showed no conv...

maximum size of gmsh *.msh-file?
is there a maximum size of a *.msh-file of gmsh to be saved as a project in elmer? in gmsh a wrote out a *.msh-file and loaded it in elmer. after the definition of equation (14 bodies), materials (quantity of 4), body force and boundary condition (280 boundaries) a saved it as a project. by copying ...
