I am now approaching to implement some interpolation procedures for some different purposes:
I am a fun of @jacobwilliams interpolotars and, indeed, I had already planned to use his libraries. However, I have just realized that for my needs two keys are necessary
Before reinventing the wheel or re-study the state-of-the-art litterature, are you aware of such a kind of interpolator libraries? Obviusly, FOSS and possible in Fortran (or Fortran-friendly).
Jacob's libraries (bspline in particular) is currently my best option: our mesh are in general very slowly-changing that can be viewed (approximated/considered) as locally uniform, but for the WENO aim a non uniform interpolator can be very useful just for only study aims.
Happy new years :tada: :tada:
@szaghi I have been using ESMF for years for interpolation, take a look at their capabilities: https://www.earthsystemcog.org/projects/esmf/regridding_esmf_6_3_0rp1
ESMF is probably not something you will want to use, but I recommend you look at it for inspiration, especially how it handles the grid-to-grid interpolation in parallel and interpolating between different domain partitions.
