ElmerSolver on Ubuntu 17.10.1

ElmerSolver is now available on Ubuntu Artful 17.10.1. This package does not contain ElmerGUI, but it does support mumps and hypre (provided by the Ubuntu Artful distribution) out of the box. Install from launchpad as follows: $ sudo add-apt-repository ppa:elmer-csc-ubuntu/elmer-csc-ppa $ sudo apt-g...

Re: ubuntu packages on lounchpad broken

These problems installing elmer on newer debian based distros is most like due to missing vtk4 support in Debian stretch and Ubuntus >16.04. https://github.com/ElmerCSC/elmerfem/issues/74

Re: VectorHelmholtz: Missing i*omega infront of Current Density

Hello, that is in fact correct. Thanks. The i*omega factor is indeed missing from the current density so the bug is either in the documentation or in the code. I am however, inclined to have this documented as a feature if someone is actually using this and circumventing the bug by just multiplying ...

Re: Comparison between ELMER and FEMM

Good to hear your experiences on elmer. I suspect that the torque ripple is due to low order of approximation. Does FEMM utilize second order elements by default? I tried your simulation (with Peter's additions) using nodal second order elements which can be generated using ElmerGrid (or with gmsh):...

Re: ElmerGrid missing

Yeah, I need to know * git commit sha1 sum, * cmake output (stdout/stderr) and cmake call arguments * make output (stdout/stderr) And if you are running make install, then I'd like to see the output of that as well. The binary ElmerGrid should appear as "<install-prefix>/bin/ElmerGrid" after install...

Re: ElmerGrid missing

Check the line 289 of top-level CMakeLists.txt (devel branch, commit c4844c3b98cce8b9ef1774a53fe0543b3230cd90). That should read

Code: Select all

ADD_SUBDIRECTORY(elmergrid)
That will include the elmergrid in to the build.

Cheers,
Juhani

Re: Automated repetition of Elmer Solver

Hi, the keyword you are perhaps looking for is "simulation type = scanning" in the "simulation" block. That way you can solve multiple steady state simulations and use the time variable as a pseudo-time. Then you can state something like angular frequency = variable time real matc "tx*a+b" Hope this...

Re: VxB fof WhitneyAVHarmonic

Hello! Yeah, the "lorentz_velo" refers to nodal interpolant to nodes of the current element of the real valued vector variable "Lorentz velocity" appearing in the sif file. So in the sif file you could have Lorentz velocity 1 = variable coordinate 2 real matc "-tx" Lorentz velocity 2 = variable coor...

Re: Errors running cmake

The ML here refers to Trilinos ML. So either disable trilinos from build options or install trilinos with ML.

Compiling Elmer against all of the libraries supported might be a tedious task so I suggest disabling as much of the WITH_* options in cmake-gui as possible.

Re: Errors running cmake

Looks like you have an in-source build where the temporary build objects are locate withing the source directory. I suggest starting from clean source directory and following compilation instructions in https://www.csc.fi/web/elmer/sources-and-compilation . Basically this just means that you shouldn...
