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 |
