Simulation Setup

Select optimal solvers for physical simulation, specify model scaling

You choose global, or model-wide, solvers through Simulink®, by using the model configuration parameters. You can also use a local Simscape™ solver for parts of the system, and adjust other options in the Solver Configuration block. For recommended choices, see Making Optimal Solver Choices for Physical Simulation.

Topics

Setting Up Solvers for Physical Models

Explains how to harmonize global, or model-wide, Simulink solvers with local Simscape solvers for physical simulation.

Important Concepts and Choices in Physical Simulation

Provides background information on advanced concepts and trade-offs to consider when you select solvers and configure other simulation settings.

Making Optimal Solver Choices for Physical Simulation

Detailed how-to information on solver selection for physical simulation.

Filtering Input Signals and Providing Time Derivatives

Ways to provide time derivatives of the input signals, required by the selected solver, and benefits of input filtering.

System Scaling by Nominal Values

Improve simulation robustness by providing scale of variables to solver.

Frequency and Time Simulation Mode

Increase simulation speed for systems with a single base frequency.
