Re: lagrangian element selection
I don't think there is a physical or mathematical reason for the elements to be discontinuous at the interface. I believe their reason is the mesh refinement is much finer in the plasma than it is in the dielectric. They likely did this to save total number of DOFs to solve. However it is not a requ...

Re: Elmer-elmag example throws error
Peter's fix works, that is the best approach.

Re: SIGSEGV Fault in parallel, but not serial
It is a difficult problem to diagnose. Not every problem can be parallel using mesh partition alone. The Elmer strategy appears to be to partition the mesh and each process acts on each mesh partition. Some codes parallel the solution equations, but each process has full access to the mesh. It may b...

Re: SIGSEGV Fault in parallel, but not serial
Almost always due to the partition strategy, in this case I expect Coil Closed = Logical True means that the whole coil has to be in 1 partition not cut over multiple partitions. Same is true for some BCs such as mortar conditions. Looks like some of the parallel processes are failing because some o...

Re: Temperature plotted in non activated body
In my case body 2 and 3 are shown with data using the threshold filter on geometry ID

Re: Temperature plotted in non activated body
What I did was load the vtu file and just displayed solid color, no results, turned on surfaces with edges to see the elements. Then I went to threshold filter and filtered on bodies 2 and 3 only and selected the desired output data, and turned on edges. This only displays bodies 2 and 3 with data, ...

Re: lagrangian element selection
Not the case in the paper, but demonstrates how different order elements can be used in different solvers using P elements.

Re: Temperature plotted in non activated body
Example of using the threshold filter to show only 2 bodies for the contour, but turning on the whole mesh without results to see whole model.

Re: Temperature plotted in non activated body
I would say it is a display issue not an Elmer issue, particularly with the contour option in paraview? I assume. The temperature data is at the nodes, the contour is being averaged across the element. The temperature is zero everywhere in the blue field, but there are values at the boundary, so par...
