Vofi — A library to initialize the volume fraction scalar field

Abstract The Vofi library has been developed to accurately calculate the volume fraction field demarcated by implicitly-defined fluid interfaces in Cartesian grids with cubic cells. The method enlists a number of algorithms to compute the integration limits and the local height function, that is the integrand of a double Gauss–Legendre integration with a variable number of nodes. Tests in two and three dimensions are presented to demonstrate the accuracy of the method and are provided in the software ... Title of program: VOFI Catalogue Id: AEYT_v1_0 Nature of problem The library computes the volume fraction of a cubic grid cell cut by an interface described by an implicit function.
