Two months ago, the simulation of 2d reaction converged fast. In order to know the three-dimensional effect of the reaction, I had a simulation of 3d reaction. Of course, the grid number grew to 1.5 million. The model is species transport. The turbulence-chemistry interaction is eddy-dissipation concept. The integration method is ISAT. The ISAT error tolerance is 10-7. The max storage is 107mb. The error tolerance is 0.05 in chemistry agglomeration. At first, one step of iteration time was 100 seconds. But it cost almost 24 hours to iterate one step. I do not know what is wrong. I really need your help!
