Hi everyone,

I am running a transient heat transfer simulation. I looked for but can't find a solution that satisfies me.

In solution settings, I have options to set both Courant # and time step size seperately. Considering my constant velocity, constant mesh size and CFL equation ( CFL#= V*deltat / deltax ); time step size and CFL number should be related. If I enter irrelevant values for them, which parameter is used by the software ?

It is similar to the question that; if I can enter time step size, why there is an option to set CFL or vice versa? (for fixed mesh and velocity)

vinerm will become famous soon enough
Refer the following

wrong solution at LOW CFL number
