Maplesoft's multidomain physical modeling and simulation software, called MapleSim, is built on a foundation of symbolic computation technology. The tool efficiently handles all of the complex mathematics involved in the development of engineering models, including multidomain systems, plant modeling, and control design. MapleSim reduces model development time from months to days while producing high-fidelity, high-performance models. Working to develop high-fidelity models of hybrid-electric and electric vehicles and the batteries, researchers Thanh-Son Dao and Aden Seaman partnered with John McPhee, the NSERC/Toyota/Maplesoft Industrial Research Chair for mathematics-based modeling and design. According to the company, they chose MapleSim because they have found the symbolic approach in MapleSim to be an effective way to develop simulation models that have fast real-time speeds for hardware-in-the-loop testing and very high fidelity compared to models created in conventional modeling tools. The system equations for the multidomain model of a hybrid-electric vehicle are generated automatically by MapleSim.
