hi all,

i'm using UDF
Inlet conditions are mass flow,
and we're using a turbulence (standard k-epsilon) models.

The machine I use is 196 cores.
but initial and iteration too slow..
The grid is 60 million in total.
more than 100 million didn't take this much.

I think my udf's mpi code is wrong, so what can I do to speed up?
Even if it's not a problem with the udf code, what is the way to speed up the calculation? Besides reducing the grid!

give me a lot of ideas to speed up the calculations, you smarts!
thank you :0
