Hi everyone

i am use the same mesh to do the calculation of a pump impeller in CFX and OF1.4.1.But i got quiet different result of torque.

X CFX-SST OF-SST

torqueZ@blade -0.452 0.1678

torqueZ@shroud -0.0161 -0.16478




would any one could tell what is wrong with my reuslt? for at blade.one is negative and one is positive?and for at shroud the OF value is too large which will cause the shaftpower to zero to sum from all rotation part.

any way the basic result was quiet simimlar as shown in p for both
CFX result

OF result


your wayne
