Dear Foamer,
I'm trying to use the interFoam to simulate the mixing of two fluids. I've uploaded the test case: 1. When running the blockMesh there is no errors. 2. After that for runing the setFields (no errors) : please do not forget to do the cp0/alph1.org 0/alpha1 before runing the setFields 3. runing interFoam : I think that there is some issues with the initialisation or may be the mesh, but I could not figure out what it is exaclty : the error message is : ---------------------------- Create mesh for time = 0 PIMPLE: Operating solver in PISO mode Reading field p_rgh Reading field U Reading/calculating face flux field phi Reading transportProperties Selecting incompressible transport model Newtonian Selecting incompressible transport model Newtonian Selecting turbulence model type laminar Reading g Calculating field g.h No finite volume options present time step continuity errors : sum local = 1.47059e+292, global = 1.47059e+292, cumulative = 1.47059e+292 DICPCG: Solving for pcorr, Initial residual = 1, Final residual = 5.19085e-11, No Iterations 66 time step continuity errors : sum local = 7.63557e+281, global = -5.03459e+279, cumulative = 1.47059e+292 Courant Number mean: 2.23052e+293 max: 1.58306e+294 Starting time loop Courant Number mean: 0.0704495 max: 0.5 Interface Courant Number mean: 0 max: 0 deltaT = 3.15844e-298 Time = 3.15844e-298 MULES: Solving for alpha1 Phase-1 volume fraction = 0.939827 Min(alpha1) = -0.114728 Max(alpha1) = 1 MULES: Solving for alpha1 Phase-1 volume fraction = 0.938477 Min(alpha1) = -0.229443 Max(alpha1) = 1 #0 Foam::error:rintStack(Foam::Ostream&) at ??:? #1 Foam::sigFpe::sigHandler(int) at ??:? #2 Uninterpreted: --------------------------------------- As you can see the sum local is too high, I think taht in the beginig of calculation some dividing by zero occured Honestly, I don't know how to fix it, do you have any ideas it would be really appreciated ! Many thanks Krimo |
