Strain rate in cylindrical coordinates
 

Hey Members,

does anyone know a solution to get or calculate the directional strain rate in the radial-, angular- and axial direction in CFD-Post?

As far as i know, FLUENT and POST does not support a cylindrical coordiante system, so the derivatives (du/dx, du/dy, ...) i can export to CFD-POST pointing to the axes of a cartesian coordinate system.

Is it possible to get the desired derivatives out of FLUENT (i dit not found them) or maybe to transform the cartesian derivatives into cylindrical components?

I am very thankful for your help!
