This publication offers a numerical scheme for the answer of box difficulties ruled by means of partial differential equations: the cellphone technique. The procedure lends itself evidently to the answer of multiphysics issues of numerous interacting phenomena. The mobilephone approach, in response to a space-time tessellation, is in detail regarding the paintings of Tonti and to his principles of category diagrams or, as they're these days known as, Tonti diagrams: a graphical illustration of the problem's equations made attainable through an appropriate number of a space-time framework touching on actual variables to one another. the most positive aspects of the mobilephone approach are provided and hyperlinks with many different discrete numerical tools (finite integration concepts, finite distinction time area, finite volumes, mimetic finite alterations, etc.) are mentioned. After outlining the theoretical foundation of the strategy, a suite of actual difficulties that have been solved with the mobile strategy is defined. those unmarried and multiphysics difficulties stem from the authors' study event within the fields of electromagnetism, elasticity, thermo-elasticity and others. eventually, the implementation of the numerical procedure is defined in all its major parts: space-time discretization, challenge formula, resolution and illustration of the ensuing actual fields.
