In the source of nonNewtonianIcoFoam solver I've found this equation:
fvVectorMatrix UEqn ( fvm::ddt(U) + fvm::div(phi, U) - fvm::laplacian(fluid.nu(), U) - (fvc::grad(U) & fvc::grad(fluid.nu())) ); It's all OK, except last operand "(fvc::grad(U) & fvc::grad(fluid.nu())".. Why do we need to do bitwise AND with grad_U and grad_Nu ??? |
