Hi Kamil, We have been trying to improve the robustness of this routine but it is quite a challenge to get a generalised interpolation of one field to another to be robust. @yumnah can you advise which branch you have been using for your interpolations since it might be good for Kamil to try that branch. Cheers Spencer.
