Hi everybody, I create a me
I create a mesh in ansa with prisms and tetraheda.
my question now, how set and interpret I the nNonorthogonalcorr ? how much is to set ?
how to interpret the residual of p.residual5, is this a convergens criterion,of p ? And how is the convergence of U when I set many nNonorth., the convergence of U is than a lot slower than convergence of p.redidual5?
much HOWs , too much !
Im really thankful for every post,
Thanks a lot
Thats the part of the log, nNonortogonal 4, relTol 0.001 tolernce 10^-6 steadystate:
DICPCG: Solving for p, Initial residual = 1, Final residual = 0.000964752, No Iterations 41
DICPCG: Solving for p, Initial residual = 0.107244, Final residual = 0.000107028, No Iterations 117
DICPCG: Solving for p, Initial residual = 0.0217492, Final residual = 2.09976e-05, No Iterations 276
DICPCG: Solving for p, Initial residual = 0.00645185, Final residual = 6.32917e-06, No Iterations 232
DICPCG: Solving for p, Initial residual = 0.00203466, Final residual = 2.03374e-06, No Iterations 528
p almost convergence with 2.03e-6 , thats the first Iteration step ( deltsT 1 ) ??
