Dear all;
I want to calculate moments on the ship hull (image attached) along z axis with center (3. 6,0,0). I want to get the viscous moments (due to viscous forces) and pressure moments (due to pressure forces) separately. I have used Fluent to do this, but now I want to use CFX for this purpose.
Is there any way to get the viscous and pressure moments separately along z-axis with center (3.6,0,0).
Waiting for a kind response

Use the CEL expressions force() and torque() to return the forces and torques. Have a look in the documentation on the details of the force and torque functions.

I think his problem is with separating viscous shear stress and pressure dependent stress .he made new question for me too!! Do you think is there a way to separate this two kind of force?

Oh sorry, misread the question.

There is a post asking this exact question on the CFX forum. Do a search for it.

In short you can use CEL expressions to integrate the wall shear to get the viscous moment and pressure to get the pressure moment.
