compressiblity
hi dear friends
density is a variable of p,T, X rho = f(X,T,p) p = pressure T = temperature X = conversion i changed the pEqn like below to consider compressiblity fvScalarMatrix pEqn ( fvm::laplacian(rhof*rUAf, p) == fvc::dd(rho) + fvc::div(rho,phi) ); but i enocunter very small time step 10 ^-11 OR less do u have any clue to increase time step with keeping courant number bounded? is using simple algorithm help to keep courant number bounded? can i use relaxation for transient solution? |
