Who We Are

• Charlie Darney (Team Leader)• Alex Kates• John Connor• Shaw Levin

• David Breen (Academic Advisor - Drexel)

• Kurt Swanson (SME – Drexel)• Ken Brakke (SME – Susquehanna)

Project Overview

• Graphical User Interface for creating liquid-based models

• Complex geometric objects– Solid phase

• Already covered by CAD

– Liquid phase• New functionality

Page 5

Project Overview

• Physics-Based Modeler performs surface evolution

• Integration to VX software

Page 6

Requirements

• Developed as an add-on module for VX CAD

• Functionality accessed via a new toolbar

• VX CAD is used to specify the base geometry of an object and define boundary conditions

Page 7

Requirements

• Toolbar contains the following functionality:– New

• Opens up a new window to allow the user to define specifications and generation procedure

– Run• Starts and displays the

evolution process

– Stop• Halts the evolution

Page 8

Requirements

• Toolbar contains the following functionality:– Rewind

• Steps backwards through the evolution process

– Export• Saves the progress of the

evolution into a selected format

– Restore• Returns the evolved liquid

object to the normal VX CAD workspace.

Social Impact

•Model generated in standard CAD system

•PBM included as utility used to model more complex, biological forms

•Improves user experiencereduces need for in depth-knowledge

•Broad range of uses

Page 14

Social Impact

•Personalization

•Speed

•Improved Results

Life Sciences

Page 15

Social Impact

•Faster development of curved facades

•Opens design possibilities to broader range of creators

Architecture

Page 16

Social Impact

•Current joints are pin and cylindrical.

•New system allows for replication of human joints.

•More lifelike and versatile.

Robotics

Page 17

Social Impact

•Modeling of virus and protein structure

•These surfaces are natural products of PBM

Micro-Biological

Page 18

Social Impact

•Competition / Implementation

•Many companies for CAD software and for PBM.

•PBM companies are very industry specific.

•CAD companies provide platform for introduction.

•VX first, then broader market
