When you scale x->c*x the coordinates the differential operator d/dx scales as 1/c. Thanks. I understand now. However, I thought when I tell Elmer about the scaling, it scales the r.h.s. automatically. Could this feature be implemented in a future Elmer release? Now the tutorial 1 is a little funny...

Thanks!

When performing analyses using the StatElecSolver I get as result "potential loads".

What unit do "potential loads" have? (Looking at the Elmer models manual I cannot find this info.)

thanks and regards

For most purposes you could scale the eigenvector so that the maximum displacement is one. This is nice for visualization. Thanks. Today I had a closer look and I realized that FreeCAD lacked most of the eigen system settings. I implemented them and now I get now sensible results. However, the resu...

Let's first FreeCAD aside and use ElmerGUI: - take the Tutorial 1 (here is the ElmerGui project: https://github.com/donovaly/FreeCADInstProj/files/9276003/Elmer-Tuto1.zip) - run the simulation result: you get around 600 K as max temperature as you should - now edit the case .sif and add the line Coo...

Dear Elmer team, many thanks for your new manuals (the ones from August 2nd)! (I like the new structure of the models manual.) Here are some mistakes I found: 1. ElmerModelsManual.pdf, page 15: "Heat Equation String If set to True, solve the heat equation." This does not work. When I input...

I am a programmer of FreeCAD's Elmer support. FreeCAD supports besides Elmer also the solver CalculiX and therefore we compare the results of both to assure we don't make mistake in FreeCAD. When I calculate the stress of a bean that is on one side fixed and has a face load on the other end. - when ...

Dear Elmer community, I am a programmer of FreeCAD's Elmer support. I stumbled over a problem I cannot resolve and need to know if this is either a bug in Elmer or if I have to edit my case.sif: The mesh coordinates in FreeCAD are in mm. Therefore we pass to Elmer: Coordinate Scaling 0.001 (and scal...
