Need for Customization

• Capture the existing simulation process

• Make repetitive operations automatic

• Integrate CAE with other in‐house analysis processes

• Make the technology available to a wider group ( CAE )(non CAE experts)

• ….

simulation process, sitting on top of a common framework


Native applications– Built entirely on WB2 Framework

Embedded within the “Workbench” window– Embedded within the Workbench window– Project Schematic, Design Exploration,

Engineering Data– Fully supported by Workbench scriptingFully supported by Workbench scripting– Scripting Language: Python

Data‐integrated applications– Share data and parameters with Workbench,

native applications, and other data‐integrated applications

– Independent UI, window

– e.g., DesignModeler, AMP, FLUENT,CFD Post…

– Scripting Language: HTML Jscript Scheme


6

Scripting Language: HTML, Jscript, Scheme, Perl …

Customization examples..

Example:• Using External Connection, HFSS parameters and properties are available within Workbench

– System acts as proxy for Ansoft HFSS application

Typical Usage:Typical Usage:• Integration of in‐house/third‐party code based on parametric input/output

Example:• Using External Connection, this simple vertical applications is builtvertical applications is built

Typical Usage:• Hosting a customi ed GUI to take• Hosting a customized GUI to take inputs and drive the simulation– Impose restrictions/constraints in input parametersp p

– Allow quick validity check for inputs and results

– Assist user in decision ki / f b hi imaking/perform branching in

simulation process• Integrate Microsoft Excel with Workbench process


8

Workbench process– Serve as a host for user inputs and simulation data management


Example:• Using Jscript add‐in, Wizard ffunctionality is added in DM

Typical Usage:• Add high‐level functionality in DM, Meshing, Mechanical etc.

• Add button/menu for extra features

bl /di bl d i ll– Enable/disable dynamically

Delphi HVAC Tool

Problem Statement:l h d• Design engineers at Delphi used a

FloWizard based customized tool for HVAC applications for more than 6 yearsyears

• Migration to new, Workbench based environment was proposed due to

Clear advantages of Workbench– Clear advantages of Workbench environment over the FloWizardenvironment

• Objective was to develop this new • Geometry and Mesh generationObjective was to develop this new, Workbench based tool and successfully deploy it at Delphi

• Geometry and Mesh generation• Various boundary & cell zone conditions

• Porous and radiator zones• Library of HX characteristics

• Flow and temperature solution

Delphi HVAC Tool – Advantages

• Bi‐directional CAD connectivity

• Optimization and parametric study in Workbench

• Reduction in overall solution time

• Reduced need for support

• No need to be a CFD expert

• Simulation is used upfront in the Design stage


16

Summary

• Automation of the CFD process for HVAC at Delphi

• ANSYS provides multiple methods to extend and customize Workbench• Python scripting Application‐level scripting External Connection add‐Python scripting, Application level scripting, External Connection addin, Workbench SDK

• Different data‐integrated applications also allow different f i itypes of customization

• Power and complexity range from basic scripting to full programmingprogramming

• Choose method that best fits your needs
