Re: 2d simulation of acoustic wave propagation

Hi Note that if the field is saved as a vector then Paraview will by default show its "Magnitude" as colour. You can always choose by its components. Then "X" would refer to Real component and "Y" to Imaginary. The selection is just right from the pull-down bar where you chose the "Pressure Wave". P...

Re: Specify screenshot boundaries in ParaView

Hi How about resizing the visualization window such that it has the same aspect ratio as the object under study. Then there will be less empty space at least. Not taking a screenshot has the advantage that in Paraview the resolution is not bound to the screen resolution. Generally, this is perhaps b...

Re: Can't open module file ‘zoltan.mod

Hi You must have gotten the source code some way. I guess it could be from ZIP package under the "Clone or Download" buttom of https://github.com/ElmerCSC/elmerfem If you have git installed you could do it as well with git clone https://github.com/ElmerCSC/elmerfem.git and update the Zoltan subrepos...

Re: Contact Surfaces MPI

To be more specific, there are test cases "ContactPatch3D*" where you can see partitioning in runtest.cmake being done such that BCs 58 and 59 (the contact pair) is married with "-connect 58 59".

Re: Any way t solve EM or MS wave porpagation in ferrites?

Hi Hale, It could be noted that the workload to add tensor valued coefficients to EM solver is not that large. Many things just hasn't been done because there just hasn't been needed. If there is a community effort and some resources things can sometimes be done quickly in a collaborative fashion. -...

Re: Contact Surfaces MPI

Hi Well, you should order the contact surfaces to be on the same partition. We have been lazy and the mortar integration assumes that it finds the counterpart in the same partition. In ElmerGrid this is done with the "-connect bc_ids" flag. For larger cases this is of course a bottle-neck. There are...

Re: Garfield+Elmer field visualization

Hi Sabrina All this can be done with ElmerSolver + Paraview. Now Garfield probably wraps around ElmerSolver with its own magic and does its own visualization. I think this interface is older than the VTU output of Elmer. You could let Elmer do the writing. The command file that you need has a suffix...

Re: Can't open module file ‘zoltan.mod

Hi

Unfortunately the subrepository where zoltan recides is not automatically obtained. You should say the following

Code: Select all

git submodule sync
git submodule update --init

Re: Parallel Computing made easier with internal partitioning

Hi

Zoltan should be activated on compile time with "WITH_ZOLTAN". Obviously the version is too old to have that. And if you compile manually remember to set it yourself.

VTU output with parts separated

Hi All, For some time there has been a feature available that writes different parts of the results into different VTU files. I have found it rather useful myself so I thought that it could be that for others too. If you have ResultOutputSolver as a solver module just add: Solver 2 ! or whatever ind...
