Designing with Parameters in Defined Variations

Explore and evaluate alternatives using parameters. By defining physics and geometric parameters, you can automate the simulation and exploration of the variations while retaining your original design. This allows you to investigate parameterized geometry changes or changes to physics conditions.

A defined variation (DVn) is an instance of the simulation that uses a set of values for all defined parameters. Output parameter values are calculated for each variation that is solved. Create new variations (manually or generate automatically) to solve all or selected variations, and then explore the solved variations in the variations chart.

In Discovery, you can make interactive modifications to the geometry and perform interactive solves, or you can set the current defined variations to revert to a set of defined parameters. The defined variations toolbar gives you complete control over any of your variations to optimize your simulation.

You may see the following tabs:

Script Parameters: Modify parameter values of parameters defined in scripts
Parameters: Manage parameterized values such as physics parameters and geometric driving dimensions
Test Cases: Create test cases by grouping physics parameters
Variations: Design alternatives using defined parameters

Note: Changes may cause some output parameters to go out-of-date. These will require an update by solving. The out-of-date icon may appear in the table or the chart and will resolve once the variation is solved.

Note: When working with time-dependent simulations, specify a time duration (Simulation > Physics > Simulation Options) before solving for all variations.
