Hello, I've started using gmsh recently, and I wonder if there is a functionality to interpolate data.
I have a mesh, and a value associated with each element of the mesh (electric potential)*. I want to use this mesh to calculate the value of the electric potential on a uniform cartesian grid specified by points (= (x, y, z) ; known in millimeters; = same unit as in $nodes) I'm guessing some sort of interpolation is needed...how would I go about it? I tried using MATLAB functions to interpolate, but they all use triangulation techniques which work for convex volumes. My volume is non-convex (it has a U-shape)...how would I do the interpolation? Does gmsh have a function to interpolate? Thank you, Mayank *I have the original mesh (containing $nodes, $elements, and $elementdata) in .msh format.
