Full MultiGrid setting
 
Hi,

I'm trying to set FMG inputs in fluent command console, and it gives me invalid command error.

> solve/initialization/set-fmg-initialization
invalid command [set-fmg-initialization]

do you know why?:confused:

Regards,

I think you need a slash between set and fmg-initialization.

solve/initialization/set/fmg-initialization

Thanks,

The command is right, but the problem was from solution initialization.
I restart the fluent and in solution initialization, by redoing the "initialization"...the command the same as I mentioned was working...

I think you need an exsiting solution to make that fmg initialisation work. Apart from that, using fmg initialisation sometimes cannot drop residual more than 3 orders in my 3D external flow cases. So be careful of it, I find hybrid initialisation is somewhat good enough.
