Hi.
How can I match to the viscous force by UDF? I need to sum pressur force and viscous force. The command to obtain the pressur force is F_P(), what's the command to obtain the viscous force? Otherwise,are there any other way to obtain it?

thanks!

I solve my own problem with

Wall_Shear_Force_X = F_STORAGE_R_N3V(f,f_thread,SV_WALL_SHEAR)[0];
Wall_Shear_Force_Y = F_STORAGE_R_N3V(f,f_thread,SV_WALL_SHEAR)[1];

( I find these funcions on the web; they are NOT on UDF manual!!!! )
