Intergraph Reader Support

The following entities are supported by the Intergraph reader:

Systems

The following systems, listed in hierarchical order, are supported and created as assemblies or components:

•	Generic systems: an assembly is created for each generic system

o	Root systems: an assembly is created for each root system

▪	Plate systems: a component is created for each plate system

▪	Stiffener systems: by default one or more components (depending on the properties you created) are created for each stiffener child geometry; this behavior can be changed based on the .ini option @CreateMultipleComponentsForStiffeners.

▪	ER systems: same as stiffener systems

o	Bracket systems: an assembly is created for each bracket system

▪	Bracket system child: a component is created for each bracket child

▪	Stiffener systems

o	Beam systems: same as stiffener systems

o	Member systems: by default a component is created for each member part; this behavior can change based on the .ini option @CreateMultipleComponentsForLinearMembers.

Compartments

By default, no compartments are imported. To import them, the @ImportCompartments or @ImportIGESCompartments .ini options should be set.

Topological Properties

By default no topological properties are created; this behavior can change based on the .ini option @ImportTopologicalProperties.

Plate Geometries

The following plate geometries are supported and created:

•

Planar

•

Curved

•	External (supported just in IGES format)

Stiffener/ER/Beam Systems Cross Section

The following stiffer/ER/beam system cross sections are supported and created:

•

Flat bar

•

Angle

•

TBar

•

IBar

•

Channel

•

Round

•	Rectangular

Linear Members

The only member parts that are imported have a straight NURBS as a contour 3D, and a cross section of type round.

Materials and Properties

By default, materials and properties are created for the Nastran solver; a different solver can be selected with the .ini option @Solver.

The following properties are created:

•	For each plate system and bracket child system, a PSHELL property is created.

•	For stiffener/beam/ER system children, the behavior depends on the analysis type (global or local analysis, see “GUI Options”):

o	Local analysis: By default, a component and a PROD property are created for each ER system child, a component and a PSHELL property are created for each web and flange of stiffener/beam system children.

o	Global analysis: By default, a component and a PROD property are created for each stiffener/beam/ER system child; if it is longitudinal, then a PBAR property is also created.

By default these properties are not assigned to the corresponding components; this behavior can be changed by using the .ini option @AssignPropertiesToComponents.

Materials are created for plate systems, bracket, stiffener, beam, and ER children; for the Nastran solver, the material created is of type MAT1.
