Hello,
You might need to calculate the torque separately or inside an UDF. Check this link [https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v221/en/flu_udf/flu_udf_sec_define_cg_motion.html?q=compute_force_and].
The above link explains how to calculate pressure force on a body. This can be modifed to calculate torque as well.
