Altair Activate enables you to model and simulate systems (including systems-of-systems) using native 1D models in block diagram form. It also provides the option to couple to 3D tools (such as MotionSolve, Flux, FEKO, etc) using multiple approaches (e.g., co-simulation) – for true multi-disciplinary system simulation. Altair Activate is especially useful for simulating “smart” mechatronic systems involving the combination of mechanical subsystems (as plant models) and electrical subsystems (as controller models) together with sensors & actuators. Your 1D models can be constructed using either a signal-based method or a physical method (based on Modelica). You can also easily import and include other subsystem models defined as Functional Mock-up Units (FMUs) using the standard Functional Mock-up Interface (FMI).
