This article will give a brief introduction to ANSYS Workbench SwiftComp GUI: An ANSYS Workbench Extension for Multiscale Modeling.

1. Introduction

Based on the recently invented Mechanics of Structure Genome (MSG), SwiftComp™ provides an efficient and accurate approach for modeling composite materials and structures. It can be used either independently as a tool for virtual testing of composites or as a plugin to power conventional FEA codes with efficient high-fidelity multiscale modeling for composites. SwiftComp™ implements a true multiscale theory which assures the best models at a given level of efficiency to capture both anisotropy and heterogeneity of composites at the microscopic scale or any other scale of user’s interest. SwiftComp™ enables engineers to model composites as a black aluminum, capturing details as needed and affordable. This saves orders of magnitude in computing time and resources without sacrificing accuracy while enabling engineers to tackle complex problems effectively.

To facilitate the use of SwiftComp™, a simple graphical user interface (GUI) based on ANSYS Workbench, called ANSYS Workbench SwiftComp GUI is developed as an extension for ANSYS.

2. Overview

2.1. SwiftComp systems at Toolbox

After ANSYS Workbench SwiftComp GUI is successfully installed in ANSYS Workbench environment, SwiftComp Homogenization and SwiftComp Dehomogenization systems will be available in Toolbox at the Workbench project level.

2.2. Toolbar in DesignModeler

In the DesignModeler, SwiftComp toolbar with Common 1D SG (Structure Genome), Common 2D SG and Common 3D SG will be available

2.3. Toolbar in Mechanical Environment

In the Mechanical environment (Model), SwiftComp toolbar with Homogenization, Structural Analysis, Dehomogenization, and Failure Analysis is available.

3. Common SG

ANSYS Workbench SwiftComp GUI provides a convenient way to create some common SG models in DesignModeler. Users can easily create the geometry of these models by input the parameters for these models. Currently, ANSYS Workbench SwiftComp GUI provides the following common SGs:

4. Homogenization

In homogenization analysis, constitutive modeling over the SG is performed to obtain the constitutive models needed for structural analysis.

For example, the figure below shows the homogenization for Solid Model.

5. Structure Analysis

In structural analysis, macro structure is analyzed by applying the homogenized material properties determined through homogenization analysis as sectional properties for beam/shell element or material properties for the solid model.

You can import homogenization result from homogenization analysis to perform structural analysis as shown in Figure below.

 

6. Dehomogenization

In dehomogenization analysis, a specific element composing the macro model is extracted to get the macro displacement, macro rotation and macro strain for determining local field, i.e. the local displacement/stress/strain for the SG.

For example, the figure shows the dehomogenization for Beam Model.

7. Failure Analysis

In failure analysis, you can perform failure strength analysis, failure envelop analysis or failure index analysis to get the strength, failure envelop or failure index/strength ratio of the SG. Note, a corresponding homogenization analysis must be run before carrying failure analysis. 

8. Download 

ANSYS Workbench SwiftComp GUI can be download from ANSYS App store: https://catalog.ansys.com/?creator=AnalySwift

You can also download it from cdmHUB (need login): https://cdmhub.org/resources/1726

Please be advised that what you download is the GUI only. You have to fill the form at  https://analyswift.com/software-trial/ to request SwiftComp from AnalySwift LLC for performing the analysis.
