Which solver for nonnewtonian flow
Im running a nonnewtonian simulation with the power law model but im having trouble getting the sim to converge. Is either simpiso or piso any better at solving nonnewtonian problems? At the mo i am trying steady state runs, could using transient help me at all?

Hi,
I have modelled a viscoelastic steady state flow with polyflow. This tool is specialised for nonnewtonian fluids. About transient, I should know more details.

Hi Joel,
Are your simulations not converging, or is convergence merely slow? In my experience, the more pseudoplastic, (n < 1) the slower convergence. Btw, the powerlaw model employed by Star is slightly different from the regular textbook (e.g. Bird) definition, Regards, Jasper
