Agenda – Simulation Driven Design (SDD) WhatIs Simulation Driven Design? Why Do it? SDD Myths & Risks How To Do it SDD Training & Resources Demo of Creo Simulate and CreoSimulation Live2

What is Simulation Driven Design (SDD)? SDD is “Design engineers using simulation tools throughout the designprocess to influence and guide the design” Also called – “CAD-Embedded Simulation” or “Democratization ofSimulation (DoS)” or “Finite Element Analysis (FEA) for Design Engineers”SDD is NOT NOT - “Design it, then throw it over the wall to Analysis and wait” NOT - “We don’t need FEA analysts anymore”This presentation focuses on SDD enabled by Creo Simulate & CreoSimulation Live3

Why do SDD? Improve Quality Prevent problems or find problems sooner Stop “throwing bad designs over the wall“ to analysisDesign Faster Iterate and Analyze designs faster and earlier in the design cycle “Simulation results in seconds rather than months”Reduce Cost Reduce weight and cost by removing material in low-stress areas and reinforcing highstress areas Explore Options & Optimize DesignsOthers are doing it “Recent trends in the simulation industry are allowing for the democratization of CAEtechnology.” “Using simulation tools targeted for non-experts, engineers can test their designs earlier inthe development process”5

SDD Myths & Risks SDD Myths Myth 1: “It’s too Hard; only Analysis experts should do it!” Hopefully this presentation & demo will dispel this myth But managers don’t want the “Wild West” where designers are doingtheir own thing and not consulting with expertsMyth #2: “It’s Easy! Anybody can do it!” “It’s very easy to make pretty pictures that are completely wrong”Risks Consider the “Risk of new tools and techniques being used incorrectly” vs.“Risk of not adopting new methods and getting left behind” Risks should not paralyze us but motivate us. Mitigate Risk with training, expert consultation, and testing/validation6

How To Do Simulation Driven Design History of SDD Hand Calcs & FBDs – Still Valid Engineering Judgement - Still Valid Advanced High-end Finite Element Analysis – Still Valid Design it, then throw it over the wall to Analysis - ObsoleteSDD Software Tools Creo Simulate, Creo Simulation Live, Creo Flow Analysis, othersTraining and mentoring Design Engineers need to know engineering fundamentals (Strength of Materials, etc) Recommend Basic FEA class from NAFEMS There is a need for practical training and guidance! Everyone is busy, so management support is critical7

How To Do SDD - Best Practices Don’t just dive in! Plan and document the project first Write a simple scope document and list the project goals Fix the CAD model first! Start simply with a small analysis project Learn simple analysis methods first before progressing to more advanced methods Check boundary conditions Use comparative analysis to predict trends “Assume results are wrong until proven correct” Automate as much as possible (Creo mapkeys, report writing, etc)8

The students also need toquickly put the training to use on pre-planned projects, so the training is not forgotten. Develop list of potential projects to be analyzed before starting training PTC University & PTC Learning Connector for online Creo training classes and tutorials NAFEMS – Basic FEA Training9

Demo – Creo Simulate & Creo SimulationLive Creo Simulate is a full FEA program intended for design engineers working on lowto-medium complexity analysis projects. Creo Simulation Live (CSL) is a new real-time simulation (FEA) tool intended fordesign engineers that gives near-instantaneous FEA feedback to help engineersquickly evaluate design options. Best practice: Use Creo Simulation Live for initial design exploration, then switchto Creo Simulate for more detailed analysis, if necessary. Pre-processing work done in Creo Simulation Live will transfer over to Creo SimulateDEMO – Accumulator Mounting Bracket12
