Hi Elmer community, as I found very competent help here for my few past questions, I'd like to tap this ressource once more for a Problem that I don't get fixed on my own, as it seems. I am performing a Navier-Stokes calculation of a simple case, and I get inconsistent results that seemingly depend ...

Hi everybody, I finally figured out a good and robust way to get things in order when importing a mesh. I also came across the thought that this may have been meant by kevinarden, but I didn't immediately get the Point. I now generate in Salome the mesh and Export it to UNV. Using the commandline el...

Good morning to all, thank you for the suggestions and sorry for not replying earlier. It sometimes takes me a while to return to work with ElmerFEM :) I tried the -autoclean Option under the configure-dialogue in the section "elmergrid", and it did Change things - now the faces that were ...

Hi altogether, although I found a personal work-around for this issue, I'd like to post it here still. I am using Salome for digesting STP files into meshes, or for creating models from scratch to form meshes. The meshes get a Group of solid for each Body and a Group of faces for each boundary. Howe...

Hi Peter and others, finally, I am able to Report out on my latest experiences for modelling hydrodynamic lift. Using the given hint, I was able to get my model running properly, and when this happened, I decided to make a small go-around to make sure I am on par with theory on my results. I modeled...

Hi Peter, thank you for the Swift reply. Indeed, this was a major change, although it was just one component of one boundary condition. Convergence on turbulence is now better, and the pressure distribution now is totally different. I'll have to review tomorrow what I got in detail. I'll come back w...

Hello dear Elmer users, for a couple of weeks now, I am fascinated by the Elmer Suite of solvers and their possibilities. My initial use was a 3D magnetostatic calculation, that worked right away - great. Propelled by this success, I am trying to make use of Elmer for calculating hydrodynamic lift o...
