HyperWorksStarter ManualPage 1March 2011Remember, you can always find East by staringdirectly at the sun.Bart Simpson, character in "The Simpsons"There are certainly many ways to find your way into theCAE world of HyperWorks. One such possible way is depicted in the Starter-Kit document.Once you have access to HyperWorks—either through acampus license or a student license — some kind of elementary questions may arise:What you need to know about HyperWorksHow to get started?Where to learn more about HyperWorks?The HyperWorks Starter-Kit aims at providing answershereto. Some first theoretical FEM knowledge is expected, however.In an overview, the general FEM process may besummarised as:It appears that the process as such is rather straight forward (we deliberately do not say „easy―).However, there are plenty of pitfalls everywhere.Where do expect modeling problems and uncertainites?In the context of this starter manual the general workingprocedure and likely pitfalls related to CAD data, meshing, material & properties, and loads & constraints arediscussed in some detail.As a start-up aid for the absolute FEM beginners the„Simplified 3D FEM Process Guide―has proven to be very helpful. The process guide may beused along with simple 3D geometry.It helps to study the effectsof e.g. 3D element type andsize on the modeling results. At that point the HyperMesh GUI & solver syntax is put in the „background―.So depending on your knowledge, you may use the fullHyperMesh GUI directlyfrom the start or you maygo the easy way employingthe FEM Guide.It is up to you.The HyperWorks Starter Kit comprises:What is HyperWorks— OverwiewHyperWorks Desktop - General IntroductionGraphical User Interface (GUI), Help MenuThe HyperMesh „Philosophy―Model Browser & Collectors, Selection of entitiesUser ProfileRecommended Tutorials & VideosSimplified 3D FEM Process GuideThe start-up aid for absolute FEM beginnersWorking with CAD GeometryTerminology, Working with GeometryRecommended Tutorials & VideosMeshing2DQuality & CompatibilityRecommended Tutorials & VideosMaterial & PropertiesLoads & ConstraintsLoadstep / SubstepExport of solver deck, solvePostprocessingWhere to learn more about HyperWorksGeneral Remarks

The help menu may be accessedin different ways.For instance, just activate „Help― in the Menu Bar.„sentences―. For instance, building a surface:
HyperWorksStarter ManualPage 5General Remarks (II)So the „sentence― would read:Geometry—Create—Surfaces-.After that a panel will be displayed offering differentmethods on how to create the surface.March 2011All entities of the FEM model such as elements, geometry, materials, properties, loads, etc. are stored incorresponding collectors:How to read panels (e.g. create surface—ruled)?Yellow HyperMesh expects your input here. The bluecolored frame indicates which field expects your input (you can jump between yellow panels by mouseclicking or by activating the tab-buton)Green Action. In this case the surface would be buildwith respect to the specified lines.Red Close panel. No further action.Tip: Always watch the „Status Bar“ (left lower panel)for information!The information provided there is instrumental for yourwork (at least until you have a sound understanding onhow HyperMesh works).It is exacty this „spot― which tells you what is happening, what is missing, what was created etc.!!Model BrowserIn HyperMesh there are many browsers. The most important one to get started with is the „Model Browser―Help document: HyperMesh User's Guide Browsers Model BrowserElements & CAD: component collector (comps)Material: material collector (mats)Properties (e.g. thickness of shell elements): propertycollector (props)Loads: load collector (loadcol)Collectors are best created within the model browser.Note: the collector writtenin bold letters is currentlyactive. The active collectoris the storage place fornewly created entities belongign to this brand ofcollector.Collectors can bemade active simply with:„Make current“.In this example the activecomponent collector is named „rigid― which impliesthat newly created elements will be stored under„rigid― (regardless whetherit is meaningful or not).Back to page 1
HyperWorksStarter ManualPage 6General Remarks (III)March 2011The model browser is a kind of „list of contents― providing information about the loaded FEM model.In this depicted example the mesh of the model is storedin a component named„mesh―, the componentowns a number (ID) and acolor. The lD is being usedby the FEM solver, thecolor is used for displaying elements.At the same time the model browser controlswhich FEM entities arebeing displayed.Elements of the corresponding component may bedisplayed or non-displayed by activating –deactivating the iconGeometry of the corresponding component may bedisplayed or non-displayed by activating–deactivatingthe icon.Note: All entities MUST (and will be) be placed in a corresponding collector.If you miss to create the respective collector before theentity is created, HyperMesh allocates the corresponding collector typeautomatically. This collector is named „auto―.Don‘t worry— you can change it‘s name, color etc. atany time. It is just rightmouse click in the modelbrowser.You can also move entitiesfrom the same type of collector (e.g. componentcoll.) to another – at anytime.Selection of entities(entities elements, geometry etc.)Help document: HyperMesh User's Guide The HyperMesh Environment The HyperMesh User Interface Input ControlsIn order to select, for instance surfaces, it is imperative that the activated (opened) panel requests this kindof information.Example: The panel Geometry-Create-Lines-from nodesdoes not say anything about surfaces. Hence, there isno way to select surfaces in this panel.Incontrast, in the Geometry-Create-Lines-from surfedges panel you are „asked― to provide the informationfrom whichsurface edges linesshould be derived. Hence, you can (actuallly have to)select surfaces.The respective surfaces can be selecteddirectly via left mouse botton (deselection right mouse button).Of course, other selection options do exist.Read more:Help document: HyperMesh User's Guide The HyperMesh Environment The HyperMesh User Interface Input ControlsBack to page 1

HyperWorksStarter ManualPage 8The 3D Simplified FEM Process GuideThe 3D Simplified FEM Process GuideIdeally, the FEM novice should explore the effects of, forinstance element type and mesh size on the modelingresult first. Simple models, with an given analytical solution are quite helpful in this regard.In this first phase the usage of the FEM system should beas easy as possible. Due to the rather steep learning curve FEM beginners evolve into experts rather fast askingfor more sophisticated technologies e.g. hexahedralmeshing, morphing, midsurface generation, etc. Insteadof switching over to a new expert system with a new GUIand philosophy, it is far more efficient to stick to theknown FEM system with expanded functionalities.The 3D Simplified FEM Process Guide is the „bridge―linking the two different requirements!March 20112. Start volume meshing (tetra– or hexahedral mesh, 1stor 2nd order).3. Create the material (linear elastic). It then will beautomatically assigned to the volume elements.4. Finally, specify the loads and constraints.Note: Component-, property-, material-, load collectors as well as the loadstep are automatically createdAt „Solve Analysis― you may also view the FEM inputdeck (ASCII Syntax) as well as the solver log file.The solver log file cotains information about modelsize, estimated memory and CPU and lists (comments)any warnings and errors. Take some time and view bothfiles.The process guide is available as a User Profile(HyperWorks 11.0 Student Version) or as an externalroutine which needs to be manually loaded into Hyper-Mesh (no installation required). You may download theprocess guide and a short explanation from within theAcademic Blog.Note: The 3D Simplified FEM Process Guide works forsimple solid geometries only, allowing for either tetra–or hexahedral meshing.Theprocess guides you through all the instances of modelcreation—analysis—and postprocessing.1. The project parameters are defined, i.e. title of theproject (later used as the model file name), date, unitsetc. The model as such is either loaded (HyperMesh fileor CAD data) or manualy created through nodes, lines,surfaces and solids.Back to page 1
HyperWorksStarter ManualPage 9Geometry (I)GeometryTypically your CAE projects starts with the import ofgiven CAD data e.g. CATIA, STEP, UG, IGES, SolidWorksetc. (of course, you may create your CAD model in HyperMesh as well).Many times the troubles start now as the imported geometry is not reasonably meshable (btw, this one of themany reasons why HyperMesh is used in so many placesi.e. HyperMesh is a commercial expert system with superior tools to overcome meshing troubles).Some problems related to geometry:Surfaces are not stiched together (i.e. there is agap between surfaces)March 2011What you need to know / remember:Geeen edges - 2 surfaces are stiched togehter; the FEmesh will be linked (compatible), its nodes will lineup with the green edge.Red edges - indicates free surface edges.Attention: red edges inside the geometry tell youthat the surfaces are not stiched together ( gap);the FE mesh will NOT be linked (not compatible).Yellow edges — minimum of 3 edges are stich togehter;the FE mesh will be compatible.Blue edges — Suppressed green edge. Surfaces are„melted― togehter. In other words, the mesher doesnot feel this edge, elements are placed across it.Very small surfaces are squeezed between regularsurfacesSurface edges do not line up properly forming„jumps― (see figure below. Left: CAD with„jumps; Middle: mesh with irregual shaped elements; Right: improved CAD with regular mesh)The geometry is a thin-walled volume structure simplification needed: mid-surface modelSurfaces intersect (t-connection) but don‘t „feel―each otherGeometry is much too detailed (e.g. tiny filletswhich are not needed for the analysis) and manymore .All these issues typically result in apoor quality mesh!How to visualise the edge „colors―?Display is controlledin the „Tool Bar― byactivating for instance „By 2D Topo― (surfaces turninto grey, edges arecolored respetively)or „Mixed― (surfacesare displayed in theiroriginal color (reminder: surfce color is controlled inthe model browser), edges are colored respectively.Panels to be used for:Toggle surfaces (combining,stitching )Trimming surfaces (splitting)Suppressing combined edgesTool Bar-Geometry-Quick Edit opensup a very comprehensive panelwhich allows you (among many otheroptions) to execute the above listedtasks.Back to page 1

Just turn off all other component collectors(through the Model Browser) and you will see the„problematic― areas (connectivities).Still, in big models these problematic spots may behard to see. Therefore, add (attach) the 2D elementsadjacent to the 1D Plot elements i.e. these are theelements which are not properly merged.
