solidThinking Activate enables product creators, system simulation and control engineers to model, simulate and optimize multi-disciplinary systems to ensure that all design requirements are successfully met while also identifying system level problems early in the design process.
Activate’s intuitive block diagram environment empowers users to rapidly build demonstrations of how real world systems function and easily try new ideas without any need to build prototypes.
The first release of solidThinking Activate 2016 provides the best-in-class, modern user experience including:
Improve system level performance
Simulate and improve the dynamic behavior of any multi-disciplinary system using Activate. Activate makes it easy to model, simulate and validate smart systems where users can incorporate functions of sensing, actuation and control coming from diverse components.
Design for robustness
Model based development using Activate provides an efficient approach for establishing a common framework for communication throughout the design process. Perform what-if analyses at the system level to quickly test several designs and investigate the interactions of all components in a system.
Gain functional insight early
Activate empowers users to identify system level problems early in the design process while ensuring that all the design requirements are met. Activate provides its users with a standard set of predefined blocks that can easily be combined to model unique systems. Activate users can easily leverage the large library of Modelica physical components to further describe the plant and the controller.
Build diagrams intuitively
Model and simulate continuous and discrete dynamic systems.
Real-world systems are multi-domain in nature. Activate allows users to model and simulate the combined system behavior of real world systems with support for multiple domains such as mechanical, electrical and others.
Hierarchical & Parametric Modeling
Built-in block-based model libraries
Activate includes a large variety of predefined blocks that are available in a library system of palettes. Users can also create their own custom blocks in C or math scripts and save them to new or existing libraries.
Physical Component Modeling Using Modelica
Easily extend the capability of Activate using Modelica. A better way to model physical components is to use implicit blocks in which the behavior of the blocks is specified through symbolic equations. Modelica, which is a standard in component level modeling is supported natively in Activate for acausal modeling.
Easily create components and assemble custom applications. Use Activate’s library manager to create and edit custom libraries. Activate also provides an IDE along with API functions for users to further leverage library management.
Activate’s simulator provides users with several high performance numerical solvers that accurately and robustly solve dynamic systems including continuous, discrete-time and event based behaviors.
|Solver Type||Stiffness||Solver Name|
|Fixed step-size||Non-stiff ODE||Forward Euler
|Stiff ODE||Backward Euler
|Variable step-size||Non-stiff ODE||CVODE-BDF-Functional
RADAU-IIA for ODE
RADAUV-IIA for DAE
Formulate optimization problems to improve the system parameters and design robust control strategies via:
Model exchange and Co-simulation via Functional Mock-up Interface (FMI)
Activate supports FMI 2.0 standard for both model exchange and co-simulation of dynamic systems including the ability to import and export FMU (Functional Mock-up Unit). FMUs can be used in context to model exchange or co-simulation.
Co-simulation with Multi-body Dynamics
The co-simulation interface lets users simulate a complex system that includes a multi-body system (MBS) and one or more control subsystems. In order to effectively simulate the entire system, the MBS is simulated with MotionSolve while the control subsystem is simulated with solidThinking Activate.
Activate allows users to create linear models from Activate blocks by linearization. The operating point can be computed either by running the simulation at a given time instant or by computing a steady-state point by imposing constraints on inputs, outputs, states and state derivatives.
Compiling models into executable code
Activate supports code generation for system performance and IP protection.
