Winning the innovation race for mechatronics products requires a tool set which can support a multi-disciplinary development process from early concept design up to in-service support. Altair Math & System Tools enable the creation of Digital Twins with purpose-driven, adjustable model complexity ranging from 0D-equations, over 1D-block diagrams up to the inclusion of Altair 3D-solvers.This presentation will cover the latest capabilities of the 2020 release and share some recent customer experience in robotics, power management, and e-mobility.
