optiSLang for ANSYS

3 ways to integrate ANSYS and optiSLang for parametric studies

• optiSLang inside ANSYS = Integration of optiSLang into ANSYS Workbench

• optiSLang ANSYS Worbench node (ANSYS inside optiSLang) = Integration of ANSYS Workbench Parameter into optiSLang

• ASCII file based interfacing including optiPlug for interfacing with ANSYS Workbench

7

important features optiSLang inside ANSYS v4.0.5



8

using continue optiSLang only send unsolved designs

Available in optiSLang inside as well: using update at optiSLang container continue or reset can be chosen

Continue crashed session option



9

Recalculate failed designs

• Due to different reasons design evaluations may fail

• With “Recalculate Failed Design Points” you can start them again



10

Update via Python scripting

• ANSYS initialize per default an update mechanism, which updates a complete ANSYS Workbench project

• Mechanism can be overridden via python file

• optiSLang provides this feature for optiSLang design evaluations

• user has full access to his ANSYS model update



11

Support ANSYS HPC Parametric Pack

• Select “Use RSM Mode” to enable parallel design point submission

• Set the “Preferred Number of Design Points in Parallel” to the intended RSM job size



12

Decision Tree for Optimizer Selection

• optiSLang automatically suggests an optimizer depending on the parameter properties, the defined criteria and user specified settings



13

optiSLang inside ANSYS

• optiSLang modules appear in Workbench toolbox

• “plug & play” - add module to project schematic

• wizard driven set up of

• Sensitivity analysis

• Optimization task

• Robustness evaluation

Easy to use



14

WB node (ANSYS inside optiSLang)

• Provide flexibility to extend the process chain



15

important featuresANSYS inside optiSLang v4.0.5



16

optiSLang 4 Integrations

Direct integrations Matlab Excel Python SimulationX ANSYS Workbench

Result Extraction usingExtraction Tool Kit (ETK)

ANSYS Abaqus Adams …

Arbitary connection ofASCII file based solvers



17

• The workbench node directly connects to the workbench project and gets the inputs and outputs from the parameter set

The WB Node (ANSYS inside optiSLang)

18

Input and Response Variables

• Scalar design variables with continuous, discrete and binary resolution and real, integer or string type

• Scattering variables with continuous resolution• Scalar responses with continuous resolution• Vector responses with continuous resolution having variable

length• Signal responses having variable length and several channels



19

WB node (ANSYS inside optiSLang)

• wizard driven setup

• Open existing project or• Connect to running project (anywhere in your network)

• Direct interface to WB parameter set will be created

• Provide flexibility to extend the process chain• add additional pre processor, solution or post

processing steps• add scalar responses or extract responses using signal

processing

Easy and flexible to use



20

important featuresANSYS Parametric Pack Licenses



21

optiSLang inside ANSYS & WB node

•Submit designs to WB design table, as a result ANSYS organize job distribution and license use

support ANSYS Remote Solve Management (RSM)

support use of ANSYS HPC Parametric Packs

• Select “Use RSM Mode” to enable parallel design point submission

• Set the “Preferred Number of Design Points in Parallel” in relation to available hardware and license resources



22

Faster turn around time for multiple jobs

Benefit of ANSYS HPC Parametric Pack

-Geometry update and Result processing will be performed sequentially on local resource

- Meshing, solution, result extraction executed in parallel

Scaling factor depend on:

-time for geometry update

-time for meshing & solution

-hardware environment



23

Get ready for RDO by multiplying base licenses

Benefit of ANSYS HPC Parametric Pack

One base license set can be multiplied by ANSYS HPC Parametric Packs

Now small, medium & large companies can increase significantly the number of parallel jobs!



24

Get ready for RDO using ANSYS HPC Parametric Pack

HPC Parametric pack is available in ANSYS workbench only

all parametric models from ANYS classic needs to be integrated in ANSYS workbench

optiSLang v4 supports integration node for ANSYS workbench including parameterization of additional responses (signals,..)

Dynardo Consulting switched to HPC Parametric Pack for all ANSYS RDO tasks Q2/2013
