Hello Friends!
I was trying to understand the code for rhopimplefoam. I was stuck at Ueqn i.e. Code:
tmp<fvVectorMatrix> tUEqn ( fvm::ddt(rho, U) + fvm::div(phi, U) + MRF.DDt(rho, U) + turbulence->divDevRhoReff(U) == fvOptions(rho, U) ); But in above we don't have values of neither rho^{n+1} nor u^{*}. Despite from this fact we know that it solves for U^{*}. So, my question how this is happening and from where is the value of rho^{n+1} is coming into the picture. I hope someone will reply. Thank You! regards |
