Default Conversion of cell velocity derivatives
Posts: n/a
Hi, In Fluent (UDF), the cell velocity derivatives are given in the cartesian coordinates (C_DUDX, C_DUDY, C_DUDZ, etc.). I want these derivatives in the cylindrical coordinates. Can anyone please help me in converting these velocity derivatives (total 9 derivatives) from the cartesian coordinate system to the cylindrical coordinate system. Thanking you in advance.
