Run Test-Case Sweep Using Parallel Simulations
Run multiple Simulink® simulations corresponding to different test cases using batchsim and Parallel Computing Toolbox™. The batchsim function offloads simulations to a compute cluster, freeing up your local machine so you can continue working while the batch job is processing. While parsim is useful for running parallel simulations on local resources, batchsim is useful for running a large number of computationally expensive simulations. If you do not have Parallel Computing Toolbox, the simulations in this example will run serially.
Multiple Simulations Workflow Tips
The goal of this example is to provide helpful tips for running multiple simulations using parallel simulation tools. This example will work even if the Parallel Computing Toolbox™ is not available, but the simulations will run in serial. We will be using the model sldemo_suspn_3dof.
