Re: Complicate Noise Source Input in Acoustic Analysis

I think he means page 94 of the Elmer solver manual which means writing and compiling an F90 user function as opposed to a solver.

Re: SIGSEGV on Arch Linux

You could turn off some of the dwith parameters like mpi etc to see if it makes a difference

Re: SIGSEGV on Arch Linux

I have received this error due to referencing a none existiNg body in the sif file. There is a VM of Elmer on the elmerfem.org site. You could try it in the VM just to make sure the model setup is correct.

Re: Gmsh + Elmer - Strange result depending on mesh type

When I translate the mesh files to Elmer mesh files the boundaries do not match up with the sif and described conditions in the picture. You may want to look at the actual boundary definitions in the Elmer mesh files.

Re: 3D Magnetic Vector Potential Lagrange Gauge Penalization

According to your geo file the model is built in mm, in the solver the units should be meters. Have you tried
Coordinate Scaling = 0.001

I think this geo file produces the same geometry

Re: Gmsh + Elmer - Strange result depending on mesh type

If you post the geo files and the sif, I can take a look.

Re: Reset boundary conditions - Running several sequences

I took the words in the manual as meaning the last defined boundary condition prevails, meaning the previous boundary condition was completely overwritten. I built a test case and you are correct, it is by specific boundary/DOF/etc. meaning they are both used unless it is the specific same boundary ...

Re: Reset boundary conditions - Running several sequences

According to the ElmerSolver manual the last boundary condition specified for a boundary prevails, meaning overwrites it not adding to it I have done this by accident in a sif file before by apply a boundary condition to the same boundary twice. The last boundary condition read prevails, the previou...

Re: Closed coil in air

Working only in the GUI is limiting. The sif file is a text file that can be edited. You can open a command line window, change to the working directory and execute ElmerSolver by typing ElmerSolver. It runs the sif file in ELMERSOLVER_STARTINFO. You can run your sif file by adding it to the command...

Re: Closed coil in air

I used Peter's five coil example to create a better sif, reduced the thickness of the coil, increased the size of the air sphere, and increased the density of the mesh. Results much improved. The mesh size was 0.15.
