Reply To: convergence problem

Unfortunately, these results don't last till convergence criteria. The paper I need to validate uses steady-state for this model. Due to computational power, I'm using a slightly coarse mesh. Somebody suggested me to play around with courant number and other parameters but that doesn't help me either. The sudden increase in residuals vanishes everything. I don't know how fmg-initialization works, but I was suggested to see if it works. I'll switch to transient as well. nn
