Re: resistance and power dissipation from StatCurrentSolver

Hi Matthias, thanks a lot, the solver works ^^ Solver 3 !Exec Solver = After Timestep Equation = SaveScalars Procedure = "SaveData" "SaveScalars" Filename = "coil characteristics.dat" End If anybody is intereseted, the solver produces two files: 1. coil characteristics.dat.names (this is the file th...

resistance and power dissipation from StatCurrentSolver

Hi all, Recently I've been working with the StatCurrentSolver and I've found that when you use "Current Control" (current fixed at Ic) the solver outputs the dissipated power as a function of the potential inposed on BC insead of power dissipated by Ic. In my simulation (see results below) I've set ...

Re: RotatingBCMagnetoDynamicsGeneric test failed

Hi all, Just a quick update on the skew feature, it took me some time staring at the MATC equation but eventually the penny dropped (tx(0) and tx(1) are always devious to interprete XD). By the way, it works in degrees. It's a very nice feature! Still working on the boundaries identification questio...

Re: RotatingBCMagnetoDynamicsGeneric test failed

Hi Peter, thanks for clarifying. I have modified the last line of the .sif file ("Solver 2 :: Reference Norm = 4.12268808E-03") and I got a PASS :D. I have some further questions, once you have extruded the 2D mesh (quarter_mesh.msh), and you are ready to prepare boundary conditions in the .sif file...

RotatingBCMagnetoDynamicsGeneric test failed

Hi all, after having downloaded from GitHub, I've tried to run the test RotatingBCMagnetoDynamicsGeneric found in https://github.com/ElmerCSC/elmerfem/tree/devel/fem/tests/RotatingBCMagnetoDynamicsGeneric and had a fail. I'm using Elmer on VM on a Mac. I've run all the commands required to build the...

Re: Fluid structure interaction and velocity BC

I see, allright, I'll stick with Elmer on VM for now and wait for news

Thanks again!

Cheers,

Re: Fluid structure interaction and velocity BC

Fantastic! I have tried it on the ubuntu VM and It works :mrgreen:

I'm sooooooooooooo happy ^^

Thanks a lot Peter!!

PS: is there any chance that we are going to see this update in the self extracting binary?

Re: Fluid structure interaction and velocity BC

Hi Peter, yes you are righ, I was just trying to understand your question and it didn't work :) what do you mean by special BC? the interface between pressure and frame surface speed/displacement? About the displacementent field, I have done some further investigations. I have taken the mesh points ...

Re: Fluid structure interaction and velocity BC

Sorry, I'm not sure I understood your question. I have checked the displacement excluding force BC and leaving only displacement BCs; the displacement field and the pressure field were all zero. Is this what you were interested in?

Re: Fluid structure interaction and velocity BC

Hi Peter, in theory it should, I have drawn the steel frame to be simmetric. I have checked the position of all the points in gmsh and they all coincide, steel characteristics are homogeneous (taken from the library), and indeed the deformed size and length coincides. If there is any other reason th...
