prikeyma is on a distinguished road

I would like to calculate the WSS gradients in a curved pipe geometry using the CEL expressions in CFX-Post. Since I am using a curved pipe geometry I cannot compute the derivative using the global coordinate system. I need to define a local coordinate system and compute the derivative based on the local coordinate system.

Does anyone know if it is possible to compute spatial derivatives in CFX based on a local coordinate system (i.e. not the global coordinate system)?
