I would like to interpolate data from an UnstructuredGrid on some points:
I’ve tried the ResampleWithDataset filter, but the interpolation fails on some points:
I’ve tried increasing the tolerance manually or changing the cell locator, but that didn’t change anything.
Are there any known pitfalls with the ResampleWithDataset filter ?
These failures seems to be linked with the kind of source mesh.
The source mesh contains quadratic cells.
It seems that using the “Extract Surface” filter to get a linear source mesh solve this issue.
It seems that the ResampleWithDataset filter is not very reliable with quadratic cells. I’ve open an issue with all data needed to reproduce this issue :
