I have problems in the coupling of OpenFOAM and FEniCSx with respect to the RBF interpolation in the FEniCSx adapter in python. The interpolation from the OpenFOAM to the FEniCSx grid works well, however in the internal interpolation in the adapter I get the following warning C:\Users\enders-seidl…

Hi Arved, Using your code from above, I was able to recreate the problem. I did not find an error when using the function = 'thin-plate'. Could you try: rbf = Rbf(coords[0, :], coords[1, :], data, function='thin-plate') It appears that the matrix is badly conditioned with the default multiquadra…
