Hi Spencer and Henrique, We have used "FieldConvert -m interpfield" module to interpolate a field to another mesh by using Nektar++4.4.1, and seems have the similar problem. We found that this problem wouldn't happen in the previous module "fieldtofield". The problem was solved after we deleted <CURVED> .... </CURVED> section in those two *.xml files. Probably because of the high-order mesh we used so that the interpfield module cannot find the proper vertices from one mesh to the another? The interpolate results look good but I'm not really sure if this step OK for further simulation. The screenshots are attached for your reference.

It is not easy to see from this image. Have you also tried 4.5.0? Cheers, Spencer.

While for the most part the result seems to be smooth and correct when visualizing the field in paraview, there are a few odd isolated cells wherein the interpolated values in the new mesh are completely off. The files to reproduce this behaviour are too big to share here, but I'm sending a screenshot to illustrate this. I'm using Nektar++ 4.4.1 and performing the computation in parallel. Any help understanding this would be much appreciated.
