Re: compile and run on Debian Jessie

Hi,
I am usually using these commands for compiling:

Code: Select all

cmake -DWITH_MPI=TRUE -DCMAKE_BUILD_TYPE=Release ../elmerfem
make -j
sudo make install
...and running:

Code: Select all

mpirun -n 1 ElmerSolver_mpi
Can you try?

InterpolateMeshToMeshQ: discontinuous fields

I am interpolating 3D nodal fields (Elmer mesh, left picture) to cell centres (OpenFOAM mesh, right pircure) using InterpolateMeshToMeshQ . Elmer mesh has multiple bodies (conductor, dielectric, ...) while OpenFOAM mesh has only one body (conductor). How can I interpolate discontinuities? https://i....

OpenMP

In the file ElmerSolver.f90, line 171:

Code: Select all

       ! Set number of OpenMP threads
       nthreads = 1
       !$ nthreads = omp_get_max_threads()
Why OpenMP is disabled in such a way?

FlowSolver: Laminar 3D flow not converging w/o stabilization

Hi! I am trying to find the reason why my simulation of laminar 3D flow ( Re ~ 1e-5 ) is not converging without stabilization. When I enable VMS turbulence model then steady state solution is found in 1 minute. Stabilization Method = VMS Full simulation case: https://drive.google.com/open?id=0ByDhKq...

MagnetoDynamics: JxB Lorentz force for complex fields

Hi! I am doing frequency-transient simulation with WhitneyAVHarmonicSolver (complex magnetic vector potential), then computing JxB with MagnetoDynamicsCalcFields and using resulting force in FlowSolver (Navier-Stokes), but it seems that Elmer does not support this functionality. Firstly, it seems th...

Re: Problems with Magnetic Induction

In the file fem/src/modules/MagnetoDynamics.F90 the comment on lines 6490-6492 says: ! Now Power = J.conjugate(E), with the possible imaginary component neglected. ! Perhaps we should set Power = 1/2 J.conjugate(E) so that the average power ! would be obtained. In other words only the real part of P...
