Re: SIGSEGV Fault in parallel, but not serial

Hi Peter, Thank you for the suggestions! My goal with this toy model is to make sure I understand the modeling procedure and can correctly simulate saturation behavior in soft magnetic materials. I have a few more details to check, but this seems to be working well. When I have everything sorted out...

Re: SIGSEGV Fault in parallel, but not serial

Hi Kevin and Peter, Thank you both very much for the help. I modified my geometry so that the center of the coil is the origin. Then it is trivial to get 4 or 8 partitions with the coil in all partitions with -partcell 220 or -partcell 222. Both do solve with a 2x and 3x respective improvement in so...

Re: SIGSEGV Fault in parallel, but not serial

Thank you. I used ElmerGrid to partition the mesh such that the coil is always entirely in one partition with the same result. I also reordered the partitions such that the coil is always in the first partition with the same result. Picture of two partitions attached. Any other advice would be appre...

SIGSEGV Fault in parallel, but not serial

Hello, I have been working on a simple electromagnetic model using CoilSolver and MagnetoDynamics. The model solves well serially, but always has a SIGSEGV fault when I execute it in parallel. I don't think it is an issue with my installation as I have solved thermal models in parallel. It also occu...
