Modelling Solutions Claytex Modelling Solutions | www.claytex.com Claytex - Software, Consultancy, Training Introduction Claytex is an engineering consultancy that specialises in In today’s automotive companies Modelica enables a single on this standard we can easily the discipline of systems model to include mechanics, couple plant models developed systems engineering, modelling and simulation. Our core engineering is growing rapidly electrical, thermal, fluid and in Dymola and controller models competency is in the modelling and simulation of complex in importance and it is common control systems. This enables developed in Simulink. This multi-domain systems, such as cars and aircraft, using practice to use many different the interactions of these systems approach enables the model models and simulation tools to be captured in the model development in Dymola to Dymola and Modelica. to support this process. These and therefore the design of focus on delivering high quality tools rarely interoperate and the complete system can be physical models and control there is usually no model optimised rather than working engineers to continue working that represents the complete on each domain in isolation. on the development of the behaviour of the vehicle. control system using Simulink. The FMI standard is an open What makes the situation worse standard for model exchange is that this lack of interoperability and co-simulation. Building means that departments working on different aspects of the vehicle will all have to spend time creating models of the parts of the vehicle they are not responsible for. This means there is a large duplication of effort and wasted resource. Claytex is a specialist partner Claytex is based in Royal Claytex also develops a number At Claytex we believe there is a for Dassault Systèmes focusing Leamington Spa (UK) and we of Modelica application libraries better way by using simulation on their range of products for have been working with Dymola and FMI based tools. Our tools that are built on open systems engineering. These and Modelica since 1999 on Modelica solutions are for standards and allow the whole include Dymola, Reqtify, CATIA a wide variety of customer modelling engines, powertrains, vehicle to be modelled in one Systems, AUTOSAR Builder and projects.
