Altair Activate software is an open & flexible tool for rapidly modeling and simulating products as multi-disciplinary systems in the form of 1D models (expressed as signal-based or physical block diagrams), optionally coupled to 3D models. Leverage a flexible spectrum of simulations throughout your development cycle – ranging from early concept design (with models involving more abstraction and typically shorter simulations) to later detailed design (with less model abstraction & longer simulations).
