Multibody models can generate large systems of differential algebraic equations (DAEs). These equations can take a significant amount of time to solve numerically and often the modeller needs to make difficult decisions between model fidelity and simulation speed.

This webinar presents some of the benefits of a general purpose symbolic computation environment when constructing and generating simulation code for multibody, multi-domain systems.  Specifically, it considers how tools provided by these environments can be harnessed to generate highly efficient simulation code through coordinate selection, symbolic manipulation, and expression optimization.

MapleSim, a modeling and simulation platform that is based on the Maple symbolic computation engine and the Modelica® modeling language is used as the investigative tool.  As a case study, different approaches to an inverse dynamics solution of a Stewart-Gough platform are modeled and exported to C-code for simulation and timing.




Presenters:
