Hello out there!
I am testing an interface between fluid flow (groundwater) and a soil deformation FE-model. Due to differences in the constitutive laws there are different discretization requirements within each of the FE models. Therefore I am looking for a fortran routine/code that will perform a kind of (linear) interpolation (or simple kriging) from the node values of the finer mesh on the coarser one.
There are some routines around that interpolate on a regular grid, bit I want an interpolation from the fine trinagular mesh to the coarser other triangular mesh.
Anybody any hints on where to find a routine that will known read x,y, value and interpolate on a new x_n, y_n field?
Regards
Hector
