....already available in the modeler s workbench . In this way, we can leverage the ongoing investment in model processing and simulation tools, and their further development. The use of a generic model description has been proposed by others as well, at various levels of abstraction, e.g. DSblock [14] for computational models and more recently Modelica [7] for mathematical models and their composites. 2.4 Assembly of Models A complete model of a system is assembled from individual model fragments by moving between the three viewpoints and inserting the proper model fragments at each layer. ....

....method, which was adapted from RADAU5. 3 Design of the SLICOT Standard Interface It is not easy to standarise currently available libraries in non linear systems. Neither the algebraic expression, nor the parameters involved are compatible in every system. Initially, a DSblock like interface [7, 8, 9, 14] was proposed. This interface deals with nonlinear control systems expressed in terms of ODEs x(t) f(x(t) u(t) p; t) y(t) g(x(t) u(t) p; t) or DAEs, f( x(t) x(t) u(t) p; t) 0 y(t) g( x(t) x(t) u(t) p; t) where x(t) 2 IR n is the state vector, u(t) 2 IR m is ....

....Graph theoretical algorithms are used for the structured analysis needed to determine causalities. Computer algebra is used to solve equations for their unknowns and performing partial evaluation at compile time, Cellier and Elmqvist, 1993) Interfacing to numerical routines is described in (Otter and Elmqvist, 1995). An new efficient mixed symbolic numerical approach for solving differentialalgebraic equations is presented in (Elmqvist, et al. 1995) 3. MATRIX EQUATIONS In mechanical modeling, matrices are essential to represent position vectors, coordinate transformations, etc. In chemical engineering ....
