Hello, Thank you for your work on VkFFT. It is very interesting. We are thinking about the integration of VkFFT inside [2decomp-fft](https://github.com/2decomp-fft/2decomp-fft). However, I think the library can not be...
This PR is a sketch for adding support for DCT / DST in the FFT backend fftw_f03. Each direction (x, y and z) can have periodicity, DCT1, DCT2, DCT3, DCT4,...
The present issue is specific to IBM simulations with spline reconstruction (`iibm=3`). The variable `ipol` can be used without being defined. This issue can lead to undefined behavior and out...
The size of the array `ypraf` is `nyraf = nym nraf`. In case of periodicity, `nym=ny`. Otherwise `nym=ny-1`. The loop used to define `ypraf` will populate the array from `1`...
Several cases estimate the integrated value of a field on - a face, for instance the inlet or the outlet - a volume, for instance to estimate the total flow...
Several all-to-all MPI reductions are using a temporary variable : https://github.com/xcompact3d/Incompact3d/blob/55652680be067db9336161b2a9c873744c637811/src/Case-TGV.f90#L298 However, MPI reductions can be performed in place to avoid temporary variables : https://github.com/xcompact3d/Incompact3d/blob/55652680be067db9336161b2a9c873744c637811/src/navier.f90#L1541 It would be a nice...
