Hi all,
I have a few questions about cgins.
1) I read the Reference Manual "Cgins: A Solver for the Incompressible
Navier–Stokes Equations" and I also looked at the reference "On the smallest
scale for the incompressible Navier-Stokes equations", but I can't figure out
if and how much the artificial diffusion (second order) influence the
simulations.
For example, if I run a simulation with \nu=1.0e-4, is it ok to choose values
for artificial diffusion ad21 = ad22 = 1? How can I know a priori if they're
too big?
2) I'd like to know precisely how the "project initial condition" option
actually work, does anyone know if there's some reference about it, or where
the source code is located in Overture?
Thanks for the help
Alessandro
