Hi everybody,
I create a meHi everybody,
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 ) ?? checkMesh: Mesh stats points: 210406 faces: 1550050 internal faces: 1440066 cells: 697760 boundary patches: 3 point zones: 0 face zones: 0 cell zones: 0 Number of cells of each type: hexahedra: 0 prisms: 189689 wedges: 0 pyramids: 9387 tet wedges: 0 tetrahedra: 498684 polyhedra: 0 Checking topology...
