Enhanced Support for Modelica
Modelica is an open standard for describing physical models and components. Many components in MapleSim are from the Modelica Standard Library. By using this open standard, engineers have full visibility into their models and the ability to modify the functionality of existing components to best suit their needs. The latest version of MapleSim increases its support for the Modelica open standard.

• Modelica Import. MapleSim users can now access new collections of components using the Modelica import feature, seamlessly including third-party Modelica libraries and their own custom Modelica components in their MapleSim models. Libraries, components, and models based on the electrical, 1-D mechanical, signals, and thermal heat flow domains from the Modelica 3.1 Standard Library can be easily imported into MapleSim and included with standard MapleSim components and models.
• Modelica 3.1 Support. MapleSim 4.5 is based on Modelica 3.1, the latest version of the Modelica Standard Library. By using the latest version, MapleSim incorporates Modelica’s improvements to many of its components. In addition, initial conditions can now be specified for all Modelica-based components, where appropriate. MapleSim 4.5 automatically converts older existing MapleSim models to use the Modelica 3.1 Standard Library, so that they can also take advantage of the latest improvements.

Increased Speed and Modeling Capabilities for Continuous Systems with Discrete Events
MapleSim 4.5 includes an improved simulation engine that can readily simulate continuous models with discrete events. The enhanced engine handles a much larger class of these systems than earlier versions, and shows significant performance improvements for existing hybrid discrete and continuous models.

• MapleSim 4.5 can efficiently simulate a wide variety of hybrid models, such as automotive clutches, electric amplifiers, active filter models, automotive stability controllers, and contact models. With the improved engine, MapleSim can now handle models that include hundreds of events.
• Models with discrete events will often run 10 times faster than in MapleSim 4, with some models running over 100 times faster.
• The improved simulation engine also results in reduced formulation times for large continuous models, shortening the time the engine requires to prepare the model for simulation.

Expanded Tool Collection
The expanded collection of tools available in MapleSim 4.5 simplifies parameter set management and provides a convenient mechanism for modeling linear discrete systems.

• MapleSim 4.5 allows customers to use Microsoft® Excel® to manage their parameter sets, so that they can easily view and access them from outside MapleSim. All parameter sets for a model can be stored in a single file so they are easy to manage, compare, share with colleagues, and access using other software in the toolchain.
• With MapleSim 4.5, engineers can easily create custom components for linear discrete systems, simply by entering the corresponding equations. Both transfer functions and state-space equations are supported. With this ability, engineers working in areas such as control system design, filter design, and system identification can easily create discrete models from their data.
