UDF to define source term at every grid point
 

Hi!

I want to write an udf, that defines a source term (eg. inertial resistance for a porous zone) at every grid point.

The values are not divided even, so I will load a table, were for every grid point the value is defined.

Now, how to write that udf??

I will read the grid point coordinates in an external programm (matlab) and calculate the value at every point. How that works, I do know...

Any Idea for the other problem??
