Hi All
I encountered a weird problem as in the subject.
Just to confirm: Can you repeat a very simple experiment:
A slab mesh and a source in the frequency domain.
I get weird values with the NIRFAST 9 (pure as download) @ frequency domain.
For a comparison, I attach the same mesh and source in frequency domain but
solved witch my GPU, parallel implementation of BiCGStab solver.
Can you confirm? I might be able to look into that at some point.
data_FD = femdata_stnd(mesh,100e6);
% data_FD = femdata_stnd_CUDA(mesh,100e6);
plotimage(mesh, log10(abs(full(data_FD.phi(:,1)))))
plotimage(mesh, angle(full(data_FD.phi(:,1))))
Continuous wave mode works fine.
