If you use prrsol command, I don't think you need multiply the reaction
force with 2*PI, because ANSYS already account this. You can do a small
benchmark say instead of initial displacement, apply a unit force and
see what your reaction force.

Riccardo,

I've tried "prrsol", it gives me the same result as "fsum", so I'm
assuming both commands are usable. The question is now do I need to
multiply the result with 2*PI to get the total force for the
axisymmetric model? Or ansys already took care of the factor 2*PI?

Thanks.
