UDF Source Term with dy/dx or dx/dy's.
 

Hello,

I would like to write a UDF for a source term which includes derivatives like dy/dx and dx/dy. Here y and x are spatial coordinates in 2D. I checked the Fluent manual for a representation of this derivative but I couldnt find one. Do you guys know any way to represent these terms as a UDF?

Thanks in advance.. Seckin
