I am getting a segmentation fault in the ArnoldiSolver function. I am using complex valued functions in H(curl) in 2D and the problem involves a pair of spaces
Assembly of the matrices seems to progress with no problems.
On a coarse mesh with cubic elements (25,992 DoF) the code works well and gives expected results. But when I try to get a more accurate solution with a finer grid in the region of interest I get this:
Generate Mesh from spline geometry
Number of DoFs: 209544
About to start ArnoldiSolver
zsh: segmentation fault netgen trans.py
The code is running on a Mac Pro (using OS 12.0.1 Monterey) and I am using NGSolve-6.2.2105.
I hope someone can help me avoid this issue. Thanks in advance!
