Simplefoam governing equations

WebbThe governing equations of a mathematical model describe how the values of the unknown variables (i.e. the dependent variables) change when one or more of the known (i.e. independent) variables change. Physical systems can be modeled phenomenologically at various levels of sophistication, with each level capturing a different degree of detail ... Webbthan adding additional force terms in the governing equations as, e.g., in the traditional immersed boundary method (IBM). We demonstrate an implementation based on the open source OpenFOAM [2] package. The OpenFOAM-Interactive (OFI) presented here gives access to all internal field variables of the governing equations. This ease and facilitates
