viscous moment -- CFD Online Discussion Forums

Thierry Guest Posts: n/a	Hello ! I'm simulating a rotating shaft in a cavity full of oil. I want to have both viscous & pressure moments on the rotating shaft. Doing 'Report / Forces / moment', I obtain : pressure moment, viscous moment, total moment, pressure coefficient, viscous coefficient, total coefficient. What is the definition of all these values ? I'm very surprised to see that pressure moment and viscous moment are of opposite sign !! - have you already met this ? Thanks
