Hello,
I try to convert a gmsh mesh to an elmer mesh using elmergrid, my mesh is ok for gmsh, unfortunately Elmergrid seems to loose some boundaries and elements...
Maybe it's because of the level of precision ?
Thanks for helping.

Re: Adaptive Mesh Refinement
Hello,
1 - I checked and some boundary elements are missing in the adapted meshes. Some divided line's triangle do not have tags. Why do the tags are not the same as the original ?
2 - The AMR is very slow to converge, is it normal ?
Best regards.

Re: Adaptive Mesh Refinement
Hello,
Thanks, now i get the adapted mesh as you in the vtu files in the RefinedMeshX folder. But there is a strange results, in the lower left part the temperature must be 293.15 in the all vertical line...seems a tag in not wright in the adapted mesh ?
Best regards.

Adaptive Mesh Refinement
Hello, I try to use the Adaptive Mesh Refinement on a simple 2D HeatSolve equation. 1 - I can't understand why the ep file doest not contain the adapted mesh instead of the original mesh. 2 - After the AMR, i'd liketo work on this "new" mesh for the following solvers like FluxSolver. 3 - M...

Streamlines
Hi everybody, I wonder which equation is used to compute streamlines of a given vector field F, litterature indicates that a vorticity equation for the streamfunction is mainly used (a laplacian equation) as follow : vorticity equation.gif The weak formulation is : weak formulation.gif It seems that...
