interpolate 3D data into a source term
 

hey guys!

I've data in a txt file in the following format:

x1 y1 z1 q1
x2 y2 z2 q2
...

Where qi is a heat source determined in HFSS (units = W/m3 and (x,y,z) are the coordinates of the mesh, which are not the same as the mesh coordinates in FLUENT.

So I suppose I have to
1) interpolate data into a function f
3) create a UDF using DEFINE_SOURCE and link that function to the grid in FLUENT

I really don't know how to implement the first step.

Thank you!
