[Nirfast] NIRFAST bug (?) in forward solution @ frequency domain

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.
