How to Automate Parameter Changes in ANSYS Discovery Live

Real-time design analysis in ANSYS Discovery Live is now more automated. Previously, you needed to manually change each parameter to see a new simulation result.

When you had multiple parameters to adjust or were curious about all possible permutations, the process of manually iterating through the parameters could be time-prohibitive.

This is where Discovery Live’s parameter study feature comes into play. It allows you to rapidly explore numerous design possibilities by automatically cycling though geometric or simulation parameters.

ANSYS Discovery Live Parameter Studies

Setting up a Parameter Study in Discovery Live

The new feature includes a menu that lets you decide which parameters to adjust and how you want to adjust them.

Parameter studies chart values

This menu lets you set each parameter’s:

  • Minimum value.
  • Maximum value.
  • Step size between each iterated value.

You can then select a target output to study based on the changing parameters.

The software will then create a 3D representation of each iterated design, instantly solve the simulation for each iteration and plot the targeted output in an interactive chart. This allows you to determine which variables and values have the greatest effect on the desired outcome.

The interactive chart can also help you better understand the trade-offs between design goals and the input parameters.

For instance, say you are designing a heat sink. You will need to decide how to make a trade-off between costs and increasing the heat sink’s surface area and resultant material consumption.

Solving problems — like this heat sink example — requires data to adequately analyze all design variations.

Using parameter studies, you can gather that data to determine which variables have the greatest impact on your design goals. This information is critical to finding an optimal design.
