Hello FOAMERS,
I am running aHello FOAMERS,
I am running a les-VOF simulation of a liquid jet of 200 bar injected into a chamber. I have been provided with the set up files which were sucessfully used to run such simulations in OF 1.4. But when I use the same set up files to run on OF 1.5. It gave me the following errors: 1. gammaCompression 1.0 , this scheme is not identified and OpenFOAM gave me a list of schemes available to solve the gamma equation, since I could not find the scheme gammaCompression 1.0 in the list, I chose interfaceCompression to solve the gamma equation. 2. Then when i tried to run the solver after this change, it solves the velocity equations for the 0 time step, but while starting to solve the pressure equation it gives me a error message as pated below: Create mesh for time = 0 Reading environmentalProperties Reading field pd Reading field gamma Reading field U Reading/calculating face flux field phi Reading transportProperties Selecting incompressible transport model Newtonian Selecting incompressible transport model Newtonian Calculating field g.h Selecting LES turbulence model oneEqEddy time step continuity errors : sum local = 0, global = 0, cumulative = 0 DICPCG: Solving for pcorr, Initial residual = 0, Final residual = 0, No Iterations 0 time step continuity errors : sum local = 0, global = 0, cumulative = 0 Courant Number mean: 0 max: 0 Starting time loop Courant Number mean: 0 max: 0 deltaT = 1.1904762e-08 Time = 1.19047619e-08 MULES: Solving for gamma Liquid phase volume fraction = 0.00033350008 Min(gamma) = 0 Max(gamma) = 1 MULES: Solving for gamma Liquid phase volume fraction = 0.00033350008 Min(gamma) = 0 Max(gamma) = 1 MULES: Solving for gamma Liquid phase volume fraction = 0.00033350008 Min(gamma) = 0 Max(gamma) = 1 MULES: Solving for gamma Liquid phase volume fraction = 0.00033350008 Min(gamma) = 0 Max(gamma) = 1 DILUPBiCG: Solving for k, Initial residual = 1, Final residual = 1.1917548e-15, No Iterations 2 bounding k, min: 0 max: 100 average: 1.2078798e-06 DILUPBiCG: Solving for Ux, Initial residual = 0, Final residual = 0, No Iterations 0 DILUPBiCG: Solving for Uy, Initial residual = 1, Final residual = 4.882832e-13, No Iterations 2 DILUPBiCG: Solving for Uz, Initial residual = 0, Final residual = 0, No Iterations 0 DICPCG: Solving for pd, Initial residual = 1, Final residual = 0.034418455, No Iterations 1001 keyword pdFinal is undefined in dictionary "/home/kumar/OpenFOAM/kumar-1.5/run/test/Offset100um_200into10bar/system/fvSolut ion::solvers" file: /home/kumar/OpenFOAM/kumar-1.5/run/test/Offset100um_200into10bar/system/fvSoluti on::solvers from line 27 to line 32. From function dictionary::lookupEntry(const word& keyword) const in file db/dictionary/dictionary.C at line 213. FOAM exiting I can see that there is no definition of Pd in the fvSolution file. But the same setting worked for OF-1.4. so is there any major change in OF-1.5 in solving the pressure equation. Any comments are welcome with regards K.Suresh kumar |
