[FLASH-USERS] V-cycle not converging

[Seyit Hocuk]

Hi,

In some of my simulations after some time into the simulation, I get a 
lot! of V-cycle warnings. What is the best way to avoid these and how 
bad are these warnings. I mean should I restart simulations or can I 
waive this warning.

Is changing "mgrid_max_residual_norm" a good option? Or should I use 
better optimizations. At the moment I am not using optimizations, but I 
noticed that using -03 reduced these warnings. How can I avoid them.

I bet you all will say that FLASH3 will solve my problems :)

Thanks,
Seyit
