The p-elements do not work with StatElecSolve.F90: I would have fun helping to make that work, but I doubt I'd be very efficient at it.

I have a mesh which is hexahedral with 27 points per element. The object is a hollow cylinder with 2 units radius and 40 units tall. Attempting to make it a parallel using command ElmerGrid 2 2 <directory> -partition 1 1 16 caused a seg fault, and a little debugging found it is in egnative.c when at...

I like higher order because it allows a cruder mesh. I will post it as a bug report. Thank you for helping me get around it!

That works! I will make note of this command and ignore the fun of debugging!
Thanks, I'm really happy that gets me back to physics.

Yes, it does work for linear elements.

On the element which causes the infinite loop, there are 4 faces in the boundary file: From mesh.boundary file: 46851 34 14398 820794 409 168389 3583 10 753 189569 3983 770 189567 189570 116219 4 820794 0 409 417324 3583 10 5842 462484 3983 5879 462482 462485 116903 2 820794 0 409 10 753 463115 5842...

Looks like an infinite loop, I assume a pointer is going out of bounds somewhere. I put in printfs in egnative.c: GetElementSide(elemind,side,normal,data,&sideind2[0],&sideelemtype2); printf("after getelements side = %d %d %d\n", side, sideelemtype2, sideelemtype); fflush(stdout); ...

I got a long cylinder to run with a single core, and now I'm trying to make it a parallel job. However, I get the following error $ ElmerGrid 2 2 deuteron_chamber -partition 1 1 16 Starting program Elmergrid, compiled on Mar 10 2024 Elmergrid reading in-line arguments The mesh will be partitioned ge...

Good to know. I will ignore them.
