Re: Using Elmer as a library from an external software

Hi Elmer is usually used as an executable. There has been some rare uses of Elmer as library but it is clearly not designed so much to be a library. Is your problem I/O critical. Often it is a simple setup to have different components coupled via the file system. ElmerGUI and Paraview always operate...

Re: Magentostatic Problem

Hi Andrew You should use MagnetoDynamicsCalcFields to get the physical fields. The primary field is the vector potential living in Hcurl space which you cannot directly visualize. Further, if you have AV appering as a field that would hint that your binary is not terribly fresh. There are plenty of ...

Re: Surface as a body in 3D

Hi Basically you can have a boundary partipaciting in the PDE as a bulk. Just give for the boundary the next free body index, for example Body Id = 2 This way you the layer can be included (just make the equation active in this new body). Now what you should do by yourself is to multiply the effecti...

Re: Inductance extraction for parallel wires

Hi Shiv Unfortunately I run your case and could not reproduce the problem. For me the inductance was constant for all tested values of current density. Maybe you could run trough some test cases that you really get the correct value when you read in Real numbers. There has been problems with localiz...

Re: Issue: NormalVector: Invalid dimension for determining normal!

Hi I had a quick look at the problem. Your problem is that you assigned "body id=1" to the boundary where you want the Reynolds equation is valid. This is problematic because the body 1 is already assigned for the true bulk body. Instead you should use an empty index i.e. "body id=2" and create a ne...

Re: Elmer crash when clicking on boundaries

Hi, Matthias has explained how it is. Thanx! We have a full project portfolio until the end of the year but none of them relates to ElmerGUI. We have done some smaller modifications to ElmerGUI when there has been more ample time but that's all. We are not too happy about this and there is certainly...

Re: Reload Existing Simulation Results with MPI

Hi Plo

I think the "ReloadSolution" solver idea was that you can load a precomputed solution for each timestep.

Re: Improved visualization of discontinuous fields

Hi spanda, How fresh is your Elmer version? Until a month or so the CalcFields was expecting the quadratic/piola settings to be consistent. Currently they should follow the primary solver. There could be also some other reason. I don't know how extensively the circuit simulator has been tested in co...

Re: periodic BC and moving mesh

Hi Martina, I see no reason why this could not work. Difficult to say where the problem lies without having access to the whole case. One possibility: if your "mesh update 2" is periodic you don't fix the absolute value. You should have at least some fixed value at some boundary for each direction s...

Re: Reload Existing Simulation Results with MPI

Hi About the restart. Restart should be possible both in serial and in parallel. The historical limitation has been that you need to start from the same mesh. The list of variables (and solvers) may be different. Only quite recently (June this year) the restart was augmented such that we may have me...
