Nastran Interface 2021.1 Release Notes
Nastran Interface
New Features
- Contact Browser Enhancements Nastran (NX)
-
- Contact browser supported in Nastran (NX) interface similar to Nastran (MSC) interface.
- Auto contact tool support extended to Nastran (NX).
- BCTSET, BGSET contact types are supported through contact browser for auto creation and manual creation.
- BSURF card migrated to set entity.
- BSURFS card migrated to set segment entity.
- ID Pool for Elements
-
- Connector elements (RBE2,RBE3,RJOINT,RBE1, GENEL,etc), Aeroelasticity panels, and structural elements can share same ID space in Nastran.
- To handle Nastran behavior, the interface now supports ID pool for structural and connector elements.
- Duplicate ID's are supported for elements, properties, aeroelasticity panel, and HyperMesh entities in the Nastran (NX) interface.
- A new solver option added in import browser, “renumber the ids to match solver ids,” for elements with shared id space are synced with solver ids during import process.
- Mechanism Browser
-
- Support of Mechanism Browser is extended to Nastran interfaces.
- Create and articulate a kinematic mechanism based on FE mesh using available joint types in the Mechanism Browser.
- In HyperWorks, the browser is invoked through Mechanism tool on the Assembly ribbon.
- LoadStep Inputs Entity
-
- New entity to migrate Nastran bulk cards from loadcolletor to loadstep inputs entity with engineering configuration.
- Some of the bulk cards, for example EIGRL, EIGRA, EIGC, NLPARM, and so forth, are migrated to loadstep inputs entity.
- Visualization Support for LOADADD
-
- LOADADD card is mapped to the loadcollector entity which is defined with a scale factor for each load in the list.
- Visualization of LOADADD is possible as a vector plot or contour including the scale factors from the Solver Browser.
- Load referenced in LOADADD must be new load management entity.
Enhancements
- General Enhancements
-
- Enable Large or Standard format export setting for individual includes.
- TABLED1/TABLES1/TABLEM1 cards with large precision are exported in comma-separated format by default.
Resolved Issues
- HyperWorks was missing “export DMIG in large format” option.
- NLPCI import issue with undefined type in NLPARM card.
- CTRIAR missed component organization on export.
