This publication provides a numerical scheme for the answer of box difficulties ruled by way of partial differential equations: the telephone technique. The strategy lends itself evidently to the answer of multiphysics issues of a number of interacting phenomena. The mobile approach, in accordance with a space-time tessellation, is in detail relating to 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 by way of an appropriate number of a space-time framework touching on actual variables to one another. the most positive aspects of the mobilephone process are awarded and hyperlinks with many different discrete numerical equipment (finite integration strategies, finite distinction time area, finite volumes, mimetic finite transformations, etc.) are mentioned. After outlining the theoretical foundation of the tactic, a suite of actual difficulties which were solved with the mobile process is defined. those unmarried and multiphysics difficulties stem from the authors' study adventure within the fields of electromagnetism, elasticity, thermo-elasticity and others. ultimately, the implementation of the numerical approach is defined in all its major parts: space-time discretization, challenge formula, resolution and illustration of the ensuing actual fields.
