Is first FOAM tutorial supposed to work flawlessly?

CThib · October 5, 2011, 13:06

Hi all,

Total babe in the woods here. I'm running the first open foam tutorial, and it runs for several iterations before I get a "continuity error" problem. Is there already a discussion started somewhere on this issue? I don't see it addressed in the tutorial. Decreasing the DT made the run go longer.

I'm assuming this is something that worked in previous versions of FOAM without a hitch?

I am running FOAM v2.0.1 on Natty 11.04.

hello CThib,

If you mean the 'time step continuity errors'. They are not faults but differences between the 'true' solution and the calculated solution and they will depend on the tolerance.
