How to smooth data (and not the mesh)?

Hi everyone,

I have a surfacic mesh with a scalar field (let’s say a temperature). I would like to apply some smoothing procedure on the temperature field, leaving the mesh unchanged. For instance a Laplacian smoothing.

I have looked at the Smooth filter but it is not clear to me if it smooths the mesh or the data. Furthermore, it has no effect on my case (even with big values for Number of convergence).

Is this possible with Paraview?

Thank you

With the TTK plugin that is shipped in the nightly and in the release starting to the really soon to come ParaView 5.10, you can use the TTKScalarFieldSmoother filter

Thank you Nicolas, I’ll try as soon as the pluging is shipped in the release.
