3 PAT312, Section 17, December 2006 S17-3 Copyright 2007 MSC.Software Corporation ELEMENT PROPERTY DEFINITION l Element Property for is used to specify: l Element type and formulation l MSC.Thermal:3D Solid : Hex8… l MSC.Nastran:Lumped Point Mass: CONM2… l ABAQUS:Solid/Standard formulation: C3D8… l Cross-section properties l 0-D:Inertia, Mass, Node Type… l 1-D:A, IYY, IZZ, J, Mass Flow, Conduction l 2-D:Thickness, Plate Offset, Material Orientation l 3-D:Material, Material Orientation l Pre-define Material Property Specification l Fields may be used to define variations: l e.g. Thickness = 0.10 * Y * X **2
4 PAT312, Section 17, December 2006 S17-4 Copyright 2007 MSC.Software Corporation ELEMENT PROPERTIES l Property forms are specific to application code, element type, and configuration l Properties can be associated with: l Geometry l FEM l Properties associated with geometry will be re-applied to new mesh after re-meshing, editing, etc.
5 PAT312, Section 17, December 2006 S17-5 Copyright 2007 MSC.Software Corporation PROPERTY DATA IS ENTERED IN CODE SPECIFIC TEMPLATES l Data templates are code, element, and configuration specific l New data templates can be custom-made for in-house Analysis codes l Fields and material properties should be defined first
6 PAT312, Section 17, December 2006 S17-6 Copyright 2007 MSC.Software Corporation VARIABLE PHYSICAL PROPERTIES l Variable Physical Property (ie. Thickness) can be specified as a function of Spatial Variables defined previously in the Field Option l Data is entered as: l In-Line PCL Expressions l Complied PCL Functions l Tables l FEM Results data l Data can be entered in the Physical as well as Parametric Coordinate Systems
7 PAT312, Section 17, December 2006 S17-7 Copyright 2007 MSC.Software Corporation SHOWING PHYSICAL PROPERTIES l Any created Physical Property may be verified using the Show Option: l To Show Physical Properties, you must: l Select the Property (i.e. Thickness,...) l Select the Display method l Tabular Spreadsheet Format l Scalar Color Fringe Plot l Marker Plot Icons designate various properties l Select Groups for which properties are to be shown l Select Apply
8 PAT312, Section 17, December 2006 S17-8 Copyright 2007 MSC.Software Corporation MODIFY/DELETE PROPERTIES l Any created Element Property Set may be Modified or Deleted l Modification can be made to any of the data corresponding to the Property Set
9 PAT312, Section 17, December 2006 S17-9 Copyright 2007 MSC.Software Corporation MASS PROPERTIES l Mass Properties application is available under Tools for 2D and 3D calculations l Can be calculated for selected groups, and can include Geometry, FEM, or both l Data can optionally be output to a text report l Output includes mass, volume, center of gravity, principal inertias at the center of gravity, the radii of gyration corresponding to the principal inertias at the center of gravity l A user specific coordinate frame may be used l Offsets and non-structural mass are ignored as well as material densities defined with fields
