iIntroductionTo the InstructorThis document introduces SolidWorks users to the SolidWorks Flow Simulation flow andheat transfer analyses software package. The specific goals of this lesson are to:1 introduce the basic concepts of fluid flow analyses and their benefits2 demonstrate the ease of use and the concise process for performing these analyses3 introduce the basic rules for computational fluid dynamics analyses and how to obtainreliable and accurate results.This document is structured similar to lessons in the SolidWorks Instructor Guide. Thislesson has corresponding pages in the SolidWorks Flow Simulation Student Workbook.Note: This lesson does not attempt to teach all capabilities ofSolidWorks Flow Simulation. It only intends to introducethe basic concepts and rules of performing flow and heattransfer analyses and to show the ease of use and theconcise process of doing so.Education Edition Curriculum and Courseware DVDAn Education Edition Curriculum and Courseware DVD is provided with this course.Installing the DVD creates a folder named SolidWorksCurriculum and Courseware 2011.

IntroductionSolidWorks Simulation Product LineWhile this course focuses on the introduction to flow analysis using SolidWorks FlowSimulation, the full product line covers a wide range of analysis areas to consider. Theparagraphs below lists the full offering of the SolidWorks Simulation packages andmodules.Static studies provide tools for the linear stress analysis ofparts and assemblies loaded by static loads. Typical questionsthat will be answered using this study type are:Will my part break under normal operating loads?Is the model over-designed?Can my design be modified to increase the safety factor?Buckling studies analyze performance of the thin partsloaded in compression. Typical questions that will be answered using this studytype are:Legs of my vessel are strong enough not to fail in yielding; but are they strongenough not to collapse due to loss of stability?Can my design be modified to ensure stability of the thin components in myassembly?Frequency studies offer tools for the analysis of the naturalmodes and frequencies. This is essential in the design or manycomponents loaded in both static and dynamic ways. Typicalquestions that will be answered using this study type are:Will my part resonate under normal operating loads?Are the frequency characteristics of my components suitablefor the given application?Can my design be modified to improve the frequencycharacteristics?Thermal studies offer tools for the analysis of the heattransfer by means of conduction, convection, and radiation.Typical questions that will be answered using this study typeare:Will the temperatures changes effect my model?How does my model operate in an environment withtemperature fluctuation?How long does it take for my model to cool down or overheat?Does temperature change cause my model to expand?Will the stresses caused by the temperature change cause my product failure (staticstudies, coupled with thermal studies would be used to answer this question)?SolidWorks Flow Simulation Instructor Guide3

IntroductionDrop test studies are used to analyze the stress of movingparts or assemblies impacting an obstacle. Typical questionsthat will be answered using this study type are:What will happen if my product is mishandled duringtransportation or dropped?How does my product behave when dropped on hard woodfloor, carpet or concrete?Optimization studies are applied to improve (optimize) yourinitial design based on a set of selected criteria such as maximum stress,weight, optimum frequency, etc. Typical questions that will be answeredusing this study type are:Can the shape of my model be changed while maintaining the designintent?Can my design be made lighter, smaller, cheaper without compromisingstrength of performance?Fatigue studies analyze the resistance of parts and assembliesloaded repetitively over long periods of time. Typicalquestions that will be answered using this study type are:Can the life span of my product be estimated accurately?Will modifying my current design help extend the productlife?Is my model safe when exposed to fluctuating force ortemperature loads over long periods of time?Will redesigning my model help minimize damage caused by fluctuating forces ortemperature?Nonlinear studies provide tools for analyzing stress in parts andassemblies that experience severe loadings and/or large deformations.Typical questions that will be answered using this study type are:Will parts made of rubber (o-rings for example) or foam perform wellunder given load?Does my model experience excessive bending during normal operatingconditions?Dynamics studies analyze objects forced by loads that vary in time.Typical examples could be shock loads of components mounted invehicles, turbines loaded by oscillatory forces, aircraft componentsloaded in random fashion, etc. Both linear (small structuraldeformations, basic material models) and nonlinear (large structuraldeformations, severe loadings and advanced materials) are available.Typical questions that will be answered using this study type are:Are my mounts loaded by shock loading when vehicle hits a large pothole on the roaddesigned safely? How much does it deform under such circumstances?SolidWorks Flow Simulation Instructor Guide4

IntroductionMotion Simulation enables user to analyze the kinematic and dynamicbehavior of the mechanisns. Joint and inertial forces can subsequently betransferred into SolidWorks Simulation studies to continue with thestress analysis. Typical questions that will be answered using thismodulus are:What is the correct size of motor or actuator for my design?Is the design of the linkages, gears or latch mechanisms optimal?What are the displacemements, velocities and accelerations of the mechanismcomponents?Is the mechanism efficient? Can it be improved?Composites modulus allows users to simulate structuresmanufactured from laminated composite materials.Typical questions that will be answered using this modulus are:Is the composite model failing under the given loading?Can the structure be made lighter using composite materialswhile not compromising with the strength and safety?Will my layered composite delaminate?SolidWorks Flow Simulation Instructor Guide5

2Basic Functionality of SolidWorks Flow SimulationGoals of This Lesson Introduce flow analysis as a tool predicting characteristics of various flows over andinside 3D objects modeled by SolidWorks and thereby solving various hydraulic andgas dynamic engineering problems. Upon successful completion of this lesson, thestudents should understand basic approaches to solving hydraulic and gas dynamicengineering problems. The students should see that the analysis of the flow overcomplex objects can influence the objects' design and performance, significantly savetime and money by performing a properly stated comprehensive CFD analysis withSolidWorks Flow Simulation instead of conducting extremely time-consuming andexpensive experimental works. Associate SolidWorks Flow Simulation flow analysis as "a chess game", in which it isvery easy "to arrange the figures over the board before the game", some effort isrequired "to obey the game rules", and it will be necessary to apply some strategy "towin the game", i.e. to obtain correct and accurate results. The students should see that,due to SolidWorks Flow Simulation's clear and well-structured interface, it is relativelyeasy "to arrange the figures over the board before the game", therefore the user willhave more time to develop a strategy of solving the engineering problem, specify theboundary conditions properly, and study the obtained results for a possible change instrategy. So, this step shows how "to arrange the figures over the board before thegame" in SolidWorks Flow Simulation. Show the students the proper ways of correctly simulating real objects and flowphenomena with SolidWorks Flow Simulation.The results of analysis may vary slightly depending on versions/builds of SolidWorksand SolidWorks Flow Simulation.SolidWorks Flow Simulation Instructor Guide6
