I want to use this commend to calculate the friction losses and slip losses by the program

I used this command, the final prestressing force not logic as the difference between the forces in the cables at deviatros very small, it is mean the program not consider the friction losses at deviators so i think i using this command incorrectly so in need ang example to understand how i can use this option correctly
