Hello,
I am doing a porous medium simulation in CFX and I have a convergence problem, in which I have to give very small time steps , so that my simulation does not diverge. However I want to give very small time steps for the beginning and the make it larger , so that the simulation runs faster. But I do not know how to do that. Should I use expressions ? |
