### Computing Derivates in Fluent UDFs

To compute the derivatives at cell centers in a user defined function, one can make use of the several macros provided by Fluent, such as C_DUDY(c,t). However, this will not work for the inviscid solver. It will only work when viscous effects are included (laminar or turbulence models). I will expand on this in the articles to follow.
