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 |
▪ | 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 |
o | Beam systems: same as stiffener systems |
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:
• | External (supported just in IGES format) |
Stiffener/ER/Beam Systems Cross Section
The following stiffer/ER/beam system cross sections are supported and created:
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.
