What it does
Use this skill to run multiple Simulink simulations in parallel with parsim, batchsim, and DesignStudy. TRIGGER when: user asks for parameter sweep, sweeping/varying parameters across simulations, Monte Carlo study, batch simulation, running multiple simulations, parallel simulations, large-scale multiple simulations, any task involving repeated simulations with different parameter values, user mentions having an existing script/function for parameter sweeps, or user wants to migrate from parfor/set_param/for-loop patterns to recommended workflows.
Running Multiple Simulations in Parallel
Set up and run parallel simulations with parsim, batchsim, or simulink.multisim.DesignStudy.
When to Use
- Parameter sweeps, Monte Carlo studies, batch simulations (local or cluster)
parsim(local parallel),batchsim(cluster offload),DesignStudy(large-scale combinations)preSimFcn/postSimFcncallbacks for setup or post-processing- Live visualization as simulations complete (ValueStore pattern)
When NOT to Use
- Single simulation →
simulating-simulink-models - Pass/fail tests →
testing-simulink-models - Model editing →
building-simulink-models
Prerequisites
If model inspection cannot resolve them, ask the user to provide: the exact model filename, the parameter name and type (workspace variable, block parameter, or model parameter), and the logged signal name(s) to use for metrics. Do not guess any of these values.
Key Functions
| Function | Purpose | Toolbox | Available From |
|---|---|---|---|
Simulink.SimulationInput | Specify per-run parameter overrides and callbacks | Simulink | R2017a |
parsim | Run a SimulationInput array / DesignStudy on a parallel pool | Simulink | R2017a |
batchsim | Offload a campaign to a cluster as a background job | Simulink | R2018b |
simulink.multisim.DesignStudy | Generate multi-parameter combinations (with .Variable / .ModelParameter / .BlockParameter / .ExternalInput / .Exhaustive / .Sequential) | Simulink | R2024a |
parpool | Create a parallel pool sized to the campaign | Parallel Computing Toolbox | R2013b |
parcluster | Query the cluster profile and worker capacity | Parallel Computing Toolbox | R2012a |
Match suggestions to the running release. The "Available From" column is authoritative: before recommending a function, confirm it exists in the release in use (version('-release')) and never propose one introduced later.
