Derivative in CFD-Post
Hi, all.

I need help!!!

Anyone knows how calculate the derivative of a variable in relation to a specific orientation in CFD-Post or in Fluent through a UDF??? For example, I have to calculate the derivative of velocity in relation to normal orientation to the gas liquid interface. I have the velocity and I calculated the normal to interface. Now only remains to calculate the derivative.
