I have done internal flow simulation for one of the control valves in fully opened condition. The inlet and outlet pressure are 3.5 kg/cm2 and 2.5 kg/cm2 respectively and i have applied local mesh near valve cross section. While solving the analysis I observed that there is much oscillations in Goal convergence graph. Is there anyway by which we can get smooth convergence graph for goals.

The goal plots and mesh plots are attached.

can anyone help me with if  you have come across this issue in solidworks flow simulation.

Thanks in advance..
