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.
