residuals error by MRFSimpleFOAM
 
hi everyone,
i use MRFSimpleFOAM to simulate a centrifugal pump impeller,it iterate 4500 steps,and the hydraulic head calculated by OpenFOAM is 65m,while the experimental head is 136m.i don't know why? and the residual as follows looks very strange,could someone mind helping me?
