Lagrange Integration problems
 

Hello!

I am doing a simulation with sand particules using the Lagrange Model. At the end of the run it says that has integration problems. I don't really know what this is. Does somebody know about it!

Thanks!!!

Most of the time, this happens when your particles get into a recirculation area. The particles never leave the domain because of this and can cause problems. Plot particle tracks to see if this is the case. You might also want to go over your integration settings to see if you have set a feasible maximum number of integration steps and max integration time.

Hope this helps, Phil
