Hei, i was wondering since in MRF the Velocity is expressed in the absolute coordinate system if i have to use rotatingPressureInletOutletVelocity at the patch where pressure is defined and rotatingTotalPressure with static pressure p0=0. with the omega of the roating frame.
When i do this i get a lot of oszialltion at the residual for p.... Am i right on this? and what would that at SRF? there is U given in relativ coordinatesystem. so i thin pressureinletoutletvelocity für U and fixedvalue 0 for p is enough? |
