I use a 64-bit version on a system by 2Gb Ram.could the problem arises from this point?or what?

I would check the source code for
Code:
ePsiThermo<Foam::pureMixture<Foam::constTran sport<Foam::specieThermo<Foam::hConstThermo<Foam:: perfectGas> > > > >::calculate() |

may be this is because of initial condition.I put pressure and temperature zero due to empty channel that should become full.is it incorrect?

for instance see this time step:
Mean and max Courant Numbers = 0.140537 0.296461 deltaT = 1.31579e-07 Time = 4.86842e-06 diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0 diagonal: Solving for rhoUx, Initial residual = 0, Final residual = 0, No Iterations 0 diagonal: Solving for rhoUy, Initial residual = 0, Final residual = 0, No Iterations 0 smoothSolver: Solving for Ux, Initial residual = 1.13168e-05, Final residual = 2.04904e-17, No Iterations 3 smoothSolver: Solving for Uy, Initial residual = 0.00894171, Final residual = 1.97135e-17, No Iterations 3 diagonal: Solving for rhoE, Initial residual = 0, Final residual = 0, No Iterations 0 smoothSolver: Solving for e, Initial residual = 1.43136e-05, Final residual = 1.55745e-10, No Iterations 201 smoothSolver: Solving for omega, Initial residual = 0.000587127, Final residual = 1.92363e-11, No Iterations 2 smoothSolver: Solving for k, Initial residual = 0.00730572, Final residual = 1.34671e-10, No Iterations 2 ExecutionTime = 38.88 s ClockTime = 58 s |
