Understanding MP-PIC implementation in OpenFOAM

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. WebFor surface and direction, phi=U can be used for determining the fluxes. In case of mode=cellZoneAndDirection, faces bounding the cellZone are extracted and processed. … Web2.3 Breaking of a dam. In this tutorial we shall solve a problem of simplified dam break in 2 dimensions using the interFoam .The feature of the problem is a transient flow of two fluids separated by a sharp interface, or free surface.
