I am trying to interpolate mesh sizes for the two different geometries each with slightly different mesh sizes. I would like to interpolate the data from these different meshes into one common sized mesh with some certain number of grid points. For example a mesh with 200,000 nodes and a mesh with 175,000 nodes are interpolated into a mesh of 150,000 nodes. The same number of grid points is critical since I will then use proper orthogonal decomposition to compare different aspects of the geometry. I have attempted the interpolation function in Tecplot but the same number of grid points remain after inverse wight or Kriging. Is Tecplot capable of changing this parameter? Any suggestions would be appreciated.
