hi
im trying to simulate a centrifugal pump with cfx. my final model composed of about 1 million elements and i adopted total pressure as inlet boundary and fixed massflow at outlet boundary.when CFX try to solve problem the residuals would not degrade less than 10-4 and have smooth variation(there is no sharp fluctuation).
is there a solution for this problem?????
thank u in advance...
