2OptiSLang Extension: IPG Automotive

optiSLang Extension for IPG Automotive software

3OptiSLang Extension: IPG Automotive

Installation:

1. Extract archive to extension directory of your choice:e.g. C:\OptiSLang\Extension or to standard optiSLang installation*

2. Add location to optislang settings / optislang.ini

*OptiSLang extensions: C:\Users\Public\Documents\Dynardo\ANSYS optiSLang\7.4.0

(please restart optiSLang after any update of the settings)

4OptiSLang Extension: IPG Automotive

Preparation of IPG *Maker project:parameterization

• Use so called named selections to define the variational parameters• Format: $NAME=DEFAULT_VALUE• Enter named selections either in the *Maker GUI or directly into the

project files

Named selection for Mass [kg]$m=1020

5OptiSLang Extension: IPG Automotive

Preparation of IPG *Maker project:response values

• OptiSLang is parsing *Maker result files of .erg or .dat format• You need to configure the output quantities in *Maker, exporting

quantities relevant for the variational study in optiSLang• OptiSLang converts .erg files to ascii files using resutils application

that comes with the installation of *Maker

Result file conventions:

• The output files needs to beexported to the „SimOutput“ directory

• The name of the test run needs to be part of the result file name

• Example:SimOutput\%D\%t%D: Date, %t: test run name

6OptiSLang Extension: IPG Automotive

Create solver chain using wizard

• Drag and drop solver wizard onto the scenery and select „IPG Automotive“ solver

• Follow the wizard steps to setup first solver chain (Parameteric solversystem):

1. First time you are using the solver wizard, you are asked for the*Maker installation

2. Select the test run file

Select solver Resulting parametric system

8OptiSLang Extension: IPG Automotive

Configuration of the IPG Automotive integration node: Settings

Name Default value Description

general.xmaker_path Please insert the path to the Maker executable Define the location of your CarMaker executable.

general.resutil_path Please insert the path to the resutil executable

Define the location of the resutil executable. Usually

it is located in the same folder as the CarMaker

executable.

general.xmaker_port 16660Define the port that will be used for the socket

connection.

general.xmaker_buffer 1024Define the buffer size for the communication with the

CarMaker application

general.xmaker_speed 5.0 Define the simulation speed for CarMaker

general.xmaker_purge 1Set this flag if the copied project directory should be

cleaned up after execution

9OptiSLang Extension: IPG Automotive

Configuration of the IPG Automotive integration node: Parameters & Responses

• Registration of the input parameters and responses

10OptiSLang Extension: IPG Automotive

(Optional) Configuration of the IPG Automotive integration node: Signals

- Use response vectoras internal variable

- Add new variable in theVariables tab and enterexpression of the followingnature: signal(Time, Values)

- Drag and drop new signalvariable to add it to theresponse list

11OptiSLang Extension: IPG Automotive

(Optional) Variation studies, e.g. Sensitivity analysis

• Once the parametric solversystem is created, optiSLang‘scapabilites for Sensitivity, Optimization and Robustnessanalysis can be used

• Example: creating field meta-models (Signal MOP) to learnabout time-dependentsensitivities of the inputparameters on the ouputsignal
