WebThe units of phi (volume flux) are m 3/ (m2 sec) which are m/s which is velocity. How phi is used specifically is related to the finite volume implementation in OpenFOAM. As i mentioned, in order to linearize the momentum equation you need to have an explicit component and not a non-linear implicit UU component i.e. U_explicit * U_implicit. WebThe recently introduced schemes in the OpenFOAM 8 work great for me: interface diffusion is removed, see attached figures.

WebicoFoam solves the incompressible laminar Navier-Stokes equations using the PISO algorithm. The code is inherently transient, requiring an initial condition (such as zero velocity) and boundary conditions. The icoFOAM code can take mesh non-orthogonality into account with successive non-orthogonality iterations. WebOpenFOAM is a computational fluid dynamics tool used in scientific research in academia and industry to solve a wide variety of complex fluid flow problems. OpenFOAM can be used to develop and test new solvers and physical models. The parallel capability is good for running research-level problems that need large resources.
