Shearrate solver

Post by hamed »

Dear Elmer
Hi
I'm using shearrate solver, however I found that it needs a too fine mesh to give accurate results. Is there any way to optimize this solver and use it effectively with a coarser mesh?
Thanks

Hi

This is a postprocessing solver. If you have solved N-S solver then this is the best presentation of the shearrate to the nodes. If you want smoother shearrate there is really no shortcut than to use denser mesh also for the N-S equation.
