hi i got this error, whenever i used smaller dt value:

Courant Number mean: 0.000635282 max: 0.0371593
Time = 4e-09

Note: i am using a volScalarField c; and i am applying a power function of the form
0.25*pow( (1- (c/cm)), -0.8), where cm is a dimensionedScalar called from transportProperties library.

Any ideas ???

thanks
