Hello there,

I am having trouble running nonNewtonianIcoFoam.
I modify this solver to include temperature. And I modify the powerLaw viscosity model to make a temperature and shear-rate dependent viscosity model.
I get the following error shown while running my_nonNewtonianIcoFoam.

Courant Number mean: 113.759 max: 584.584

Can someone please explain why this is happening, and how to set it up correctly?
