Hi all;

I recently noticed the mistake i have made when doing the convectiveOutlet simulation. I defined the startFrom in the controlDict as latestTime. Now, i have fixed it, and the results...

Hai pU|,

I have run the simulation again, and this time i was using backward second order time discretization scheme. No problems arise this time and i got smooth force oscillation.

I think...

Hi Foam'ers,

I hope i was not to late to join the discussion.

Currently i was doing simulation of flow over a square (2-D) at Re = 150, low Mach number. I defined the outlet as...
