Abstract: A unified approach on teaching and modelling 1D dynamic Multiphysics systems has been investigated, re-organised, elaborated and applied. While the presented method is of the system-dynamic kind, a 1:1 equivalence to the tetrahedron-of-state-concept within the well-known bond graph modelling technique can be shown. Gibbs fundamental equation is an essential theme within the demonstrated approach. It constitutes the basis and justification for modelling any Multiphysics system. The method involves a thorough distinction between capacitive- and inductive elements. Furthermore it proposes graphical tokens to represent relevant phenomena. Among the central modelling elements are containers for conservative quantities, capacities, inductivities, potentials, equations of state as well as fluxes of information and physical quantities. While being most practical and efficient for zero- or one-dimensional problems, there is no theoretical limitation towards modelling two or three- dimensional scenarios. Thus the presented concept enables fast instructive representation of linear- and angular-, mechanical-, electrodynamic-, fluiddynamic- and, with limitations concerning inductive processes, also the representation of thermodynamic- as well as thermochemical systems. In this context, selected examples of first order capacitive-inductive, mechanical-, fluiddynamic- and electrodynamic systems will be shown in order to demonstrate the applicability, efficiency as well as validity of the modelling concept in discussion.
