I think your conclusions is correct. We did some early implementation into the 2D Homogeneous expansion but have not pulled it all the way through since we did not have a full project on this topic. We have however kept the existing code running through our regression test. For now I would perhaps suggest you try the 3D homo 1D approach for your runs since you can use parallelisation in that code.

Dear all,

I just installed the library, and need to simulate DNS of a channel flow
with oscillating pressure gradient.
As I have two homogeneous directions I applied standard Fourier
discretization in these directions.

It seems like this case is not parallelized yet, and I got the error in
the subject.

I was wondering if I'm overlooking something. If not, are there maybe
any plans in the future to include parallelization of 2D FFT's?

Thank you in advance.
