converge solver slow problem
 

Hello,

I meet a problem when I execlute the converge solver 2.2. When the engine working time comes to embeded, spray and combustion, the processing become very slow and CPU usage decrease to a very low value (about 8%).

But I calculated the same case 6 months ago and got the whole result. Stuck in this problem for nearly half month. I am really confused. :(

I would really appriciate it, if you can give any advices.

Best wishes.

addition
 

about why I use the converge solver 2.2. It is because the model was established long time ago and some valueable data was gotten form the model. I prefer keeping the model in 2.2 rather than established a new model again. It's a huge work and kill the consequence of the old data.:D thank you!
