Doubts residue criterion CFX

TallesC · May 25, 2016, 09:15

guys,

guys, I'm conducting state gas leakage simulation steady for the environment all variables converge perfectly around 1,000 interactions but wall boundary and scale not converege and ends up delaying the simulation does anyone know if it possible to determine a residue of higher convergence for this variable (eg 10-3), the studies did she not influence the final result.

Thanks

Not sure if I'm right but since I'm simulating with CFX the wallscale will always remain constant at around 5e-5 after about 3 iterations. So is that what you think is a problem?
Also, in CFX Convergence only the u,v,w-Momentums are considered for the target.

in my case parking just above 1E-4 remaining constant until the end of the simulation that for the interactions of number of criterion (2000), while all other reaches 1E-5 residues in about 1300 interactions.
