Change BC during the run?

jx

Hi, all,

Is it possible for me to use some kind of BC seetings to get an initial flow field after certain iterations, and then change the BC and continue the run untill converged?

For example, I use a guessed temperature level at a wall to get an initial solution, and then change the temperature condition for that wall to constant heat flux condition and hope to get the real solution.

I don't know how fluent saves case information, but I feel if I continue the iterations from previous saved .cas and .dat files, fluent always picks up the previous boundary condition seetings and does not take the newly modified BC.

How can I do this?

Thanks,

jx
