Dear all,

With respect to my previous question, I looked into paraview forum and found similar question and solution to it. The forum link is provided below.

With respect to this, I tried methods which include SPH Dataset Interpolater from the Temperature field parameter or the csv dataset which includes points of x,y,z and T values.

As far as my work, the steps done as follows:

1. Upload stl file obtained from meshlab
2. Upload csv file with Temperature dataset and convert to TableToPoints.
3. Do SPH Dataset Interpolator

From this, I could get extra temperature column but with only 0 and nan values. I actually wanted the temperature data to be on the surface of stl file like a gradient. Please let me know what wrong have I done or is there anything I need to do.

I have attached the images for reference. I have also attached the link for csv file and stl file.
