MotivationNew product in the ANSYS portfolio:

Maxwell, for doing electro-magnitic simulations

Since ANSYS V12 „Maxwell“ can be directly imported to the ANSYS Workbench project page via „External Connection“

The transfer of the Maxwell parameters andthe interface to optiSLang in Workbenchallows a completely automized workflowwhich can be used for stochastical explorations.

Task: Optimization of the force-position signal of a pneumatic outlet

To adjust the volume flow it is important to know the force-path characteristic of a pneumatic outlet.

In this task the objective is to get a predefined characteristic curve where the force on the pusher is defined by a given position.

The signal should be adapted to the given force-displacement curve. This will be realized by changing geometry parameters.

Objective


17

Interface to ANSYS Workbench: Create Workbench Project

The parameters will be transfered to Workbench.

Now changes can be made in the parameter set.

optiPlug – the interface between ANSYS Workbench and optiSLang

Necessary files for optiSLang are created automatically,no scripting..


21

Parametrization of signals

This is done by scripting

à Use Maxwell Script Writer

à Couple „optiPlug Input Parameters“ with „Script Input Parameters“

Parametrization The parameter tree lists the predefined parameters from Maxwell.

By double-clicking on the parameter you can insert an upper and lower bound.

Now the variability of each parameter is defined.

Output

The correlation matrix shows the correlation between Input & Input, Input & Output, Output & Output.

These are the parameters with the most affect on the objective.

à 6 input parameters are taken into account for further evaluations

Signal Data for 45 Designs

For each parameter one force-path characteristic can be obtained. The next step is to optimize the characteristic.
