Hello,
I want to perform an aeroacoustic simulation in which I am using APESolver (nektar-4.4.1). I am transferring the source terms from the fluid solver (OpenFoam) to nektar++. I need to interpolate the source terms from the finite volume mesh (which is relatively coarser) ino the spectral mesh which can be used by APESolver. Initially, I used Shepard's algorithm to interpolate the source terms which performed well for serial runs but, unfortunately, there are several numerical errors when I am passing the data using multiple processors.

Recently I found out that there is an already available utility in nektar++ for field interpolation ( as post-processing utility). I wanted to inquire if it is possible to use the functionality for interpolating the data during runtime with multiple processors.

Happy new Year to all of you!!
