Detailed Description

Compute the local time step and add the Courant and Fourier number to the log.

When using an adaptive time step (idtvar = 1), coupling syncronization and update (incrementation) of the time step is done in the function (rather than earlier) as soon as the required information is available.

This function has access to the boundary face type, except for the first time step.
