friendly accessible professional relevant DynLAB EdTech 2004 friendly accessible professional relevant DynLAB DynLAB is a Project Funded under the EU Leonardo Scheme Partners: Czech Republic, Germany, England, Ireland and Sweden Aim: To Develop and Disseminate a Web Based Course on Dynamics and Control of Multidisciplinary Engineering Systems

friendly accessible professional relevant DynLAB EdTech 2004 friendly accessible professional relevant DynLAB Course set out to introduce Modeling Method and then to bring in Control Elements. Hopefully will use Virtual Experiments with Animations of Physical Systems Aimed at three levels of participation. High School Student College Student Practising Engineer

friendly accessible professional relevant DynLAB EdTech 2004 Dynamics Involves: Modelling: Development of Mathematical Equation(s) representing a physical system. Simulation: Using the Mathematical Model to understand and optimise “system” behaviour.

friendly accessible professional relevant DynLAB EdTech 2004 friendly accessible professional relevant Review of Method: Traditional Traditional approach has followed a process as follows Development of Model based on Physical Laws that relate Input to Outputs. So we set up a model by considering the inputs and outputs.

friendly accessible professional relevant DynLAB EdTech 2004 friendly accessible professional relevant Review of Method: New Method Key to DynLAB is a Software Package “Dynast” Multipoles model energetic interactions between a component and the rest of the system assuming such interactions take place at a limited number of energy entrances. Dynast allows for unified modelling and simulation of mixed energy-domain systems based on multipoles.

friendly accessible professional relevant DynLAB EdTech 2004 friendly accessible professional relevant New Method Dynast provides a predesigned set of multipoles. that can be placed as in a CAD package. Dynast also links to Matlab. Free Across the Web in different modes A multipole only has to be formulated once and can be then reused. Can create library of multipoles models for different engineering disciplines.
