Abstract
In the context of a multimaterial domain, the GFM for the Laplacian operator is reformulated from an algebraic perspective, where operators are represented by matrices. From this perspective, a whole new level of analysis can be attained. Namely, conceiving mass, heat and momentum transfer applications, the discretization of both value and flow discontinuities is discussed, with particular emphasis on extreme contrast interfaces, such as those arising in liquid-vapor mixtures. Regarding ¿ow dis...
