Hi all,
I am trying to study the instability of boundary layer flows by modifying icoFoam solver to create the LNSE solver, I have made the following changes to the standard icoFoam solver, where U is the perturbation term and UB the base flow velocity dirIcoFoam.c: (modified part in icoFoam) Code:
fvVectorMatrix UEqn ( fvm::ddt(U) + fvm::div(phiB, U) + fvc::div(phi, UB) - fvm::laplacian(nu, U) ); Code:
Info<< "Reading field UB\n" << endl; volVectorField UB ( IOobject ( "UB", runTime.timeName(), mesh, IOobject::MUST_READ, IOobject::AUTO_WRITE ), mesh ); surfaceScalarField phiB ( IOobject ( "phiB", runTime.timeName(), mesh, IOobject::READ_IF_PRESENT, IOobject::AUTO_WRITE ), fvc::flux(UB) ); Current methodology to approach the problem:
Also, i would appreciate if anyone found an error in my code and made me aware of it! Thank you |
