ASSIGN FINE MESH VALUES TO A NEW COARSER MESH

Hello,

I am having an excel sheet with fine mesh coordinates and corresponding loads (around 6000 coordinates). However, I wanted to assign these fine mesh coordinates loads to a new coarser mesh coordinates (around 2000 coordinates) based on the nearest coordinate values. Is there any possible way to solve the problem?

Thanks in advance.

It depends on how your mesh is. Is unstructured or structured. If structured mesh you can use interp2 or griddata. If it is unstructured have a look on knnsearch.

Also have a look on scatteredInterpolant.
