[Paraview] Field variable interpolation on different meshes

In the spirit of estimating the error of a numerical scheme (using Richardson's extrapolation), I computed a cell-centered solution on two different 2D meshes of size h1 and h2, where h2 > h1. Now my question is: how can I interpolate the solution (say density) A1(h1) on the finer mesh h2 so to obtain A1(h2)? Then how would I subtract both fields likewise: A2(h2) - A1(h2)?
