Thank you for your reply !
I found this information in ANSYS help:

I have saved data file including wall shear stress components. However, it seems that "the viscous force is added only in the wall boundary".
The pressure force is straightforward. How about the "mass flow force"?
I found the command "force_x()", is it total force? How it can be calculated by ANSYS?
Thank you so much!
