Unsteady Simulations - NITA
 

Hey,

I'm interested in using the Non-Iterative Time-Advancement Scheme (http://www.ipt.ntnu.no/manuals/Fluen...ec-frozen-flux) to compute an unsteady flow situation.

However, I'm not sure how to set the convergence criteria in Fluent. When enabling the Non-Iterative Time-Advancement option under define->models->solver->unsteady, the residuals' criteria under solve->monitors->residual are depressed - I can't alter them.

Hence, I was wondering which criteria the algorithm uses to define whether a computation has converged and how I could I change the convergence criteria?

Many thanks,

CC

Define residual tolerences in "Solution Control" panel.
