7 PAT312, Section 1, December 2006 S1-7 Copyright 2007 MSC.Software Corporation BUILDING A MODEL USING MSC.PATRAN The Main Form 2 - Import Geometry 1 - Select Analysis Code 2 - Build Geometry 3 - Create Analysis Model 5 - Evaluate Analysis Results 4 - Perform the Analysis

8 PAT312, Section 1, December 2006 S1-8 Copyright 2007 MSC.Software Corporation STEP 1 - ANALYSIS PREFERENCES Appears when creating a new database Also used for specifying global model tolerance Alternative method for specifying global model tolerance is Preferences/Global New Model Preferences

9 PAT312, Section 1, December 2006 S1-9 Copyright 2007 MSC.Software Corporation STEP 1 - ANALYSIS PREFERENCES (CONT.) Select/Revise Analysis Code Preference before defining Materials, Element Properties, or Load/Boundary Conditions Analysis Preferences eliminates the confusion

10 PAT312, Section 1, December 2006 S1-10 Copyright 2007 MSC.Software Corporation l Geometric Modeling: l Import a CAD model from l CATIA l Pro/ENGINEER l CADDS 5 l EUCLID-3 l Unigraphics l Import a CAD model via an IGES, ACIS, Parasolid-XMT, or STEP file l Build the geometry model entirely in MSC.Patran STEP 2 – IMPORT/BUILD GEOMETRY Imported CAD model

11 PAT312, Section 1, December 2006 S1-11 Copyright 2007 MSC.Software Corporation STEP 3 – CREATING AN ANALYSIS MODEL l Finite Element Mesh l Nodes and Elements (connectivity) can be created by: l Mapping Mesher (IsoMesher) l 3 or 4-sided surfaces (displayed as Green) l 5 or 6-faced solids (displayed as Blue) l Paver Mesher l N-sided (edged) trimmed surfaces (displayed as Magenta) l 3 or 4-sided surfaces (displayed as Green) l Auto TetMesher l N-faced solids, B-rep Solids (displayed as White) l 6-faced solids (displayed as Blue) l Sweeping Base Elements Mesher l Mesh Seeds are used to define the node density and spacing Quads swept to Hex Elements X Y Z Mapped Mesher Quad Elements X Y Z

12 PAT312, Section 1, December 2006 S1-12 Copyright 2007 MSC.Software Corporation STEP 3 – CREATING AN ANALYSIS MODEL (Cont.) l VERIFICATION l Check the quality of the finite element model l Element Boundary Checks (crack detection) l Element Nodal Connectivity (Normals, Negative Volume) l Element Distortion Checks (Aspect Ratio, Face Taper, etc.) l Elements are color-coded based on user-defined criteria

13 PAT312, Section 1, December 2006 S1-13 Copyright 2007 MSC.Software Corporation STEP 3 – CREATING AN ANALYSIS MODEL (Cont.) Material Properties The material properties can be manually input or accessed from the MSC.Patran Materials Selector. Manual InputMaterials Selector

14 PAT312, Section 1, December 2006 S1-14 Copyright 2007 MSC.Software Corporation STEP 3 – CREATING AN ANALYSIS MODEL (Cont.) Element Properties Element type and physical properties defined with the Properties application Once the analysis code preference is chosen only permitted physical properties are available If detailed information is needed, the interface manuals are on-line
