hi
I wanted to solve a problem of a non-Newtonian fluid through an expansion of a 2D tube. I set a timeVaryingInletOutlet for velocity at the inlet and a time series for pressure at the outlet using timeVaryingFixedValue. viscosity model is BirdCarreau. I do not know what the problem is but the thing printed in the terminal is:
Courant Number mean: 0 max: 0

Floating point exception
anyone knows how I can fix the problem?
