Unformatted text preview: IMPORTING GEOMETRY FROM SOLIDWORKS INTO ABAQUS/CAE T5-1 TUTORIAL T5 IMPORTING GEOMETRY FROM SOLIDWORKS INTO ABAQUS/CAE For historical reasons, Abaqus/CAE generally targeted the analyst rather than the designer. With respect to importing CAD geometry, it had featured only a general CAD interface method, i.e., one in which /CAE was not so tightly coupled to CAD systems. Most CAD designs could and still can be imported for analysis by /CAE using this standalone method. 1 When an acceptable geometry file of a part or assembly does not exist at the beginning of a finite element analysis project, one must decide whether to use either a CAD package or Abaqus /CAE to generate the geometry for purposes of analysis. Before deciding one should consider that use of perhaps a more familiar or convenient CAD package could result in a file that requires special handling including geometry repair after it has been imported into /CAE. This should be weighed against avoiding importation of a CAD file, when possible, and using /CAE to generate the geometry of the part or assembly directly so that geometry repair is less likely. Alternatively, it is possible that an acceptable CAD geometry file exists at the outset, or that previously generated geometry in the form of a mesh from an Abaqus/CAE input or output database file exists. In the former case, the geometry is imported from the CAD system, and in the latter case, it is imported as an orphan mesh part (not discussed; see Section 11.6, ABAQUS/CAE User's Manual). Tutorial T5 demonstrates the two basic methods for importing CAD geometry files into Abaqus/CAE: (1) a standalone CAD interface method, and (2) an associative import (AI) interface method. Method (1) is illustrated with earlier versions of Abaqus/CAE and SolidWorks in Example T5-1. Method (2) is a more method that tightens the coupling of CAD packages to /CAE. This method is illustrated in Example T5-2. It requires Abaqus/CAE Teaching Edition version 6.7EF or higher, and SolidWorks, version 2008 or higher. 2 Geometry repair is needed when imported geometry is either invalid or imprecise. It is demonstrated in Example T5-3. 1 The reader is referred to Ch. 10 of the ABAQUS/CAE Users Manual, Importing Geometry with ABAQUS/CAE from a CAD System. 2 Abaqus academic licenses include the SolidWorks AI interface. IMPORTING GEOMETRY FROM SOLIDWORKS INTO ABAQUS/CAE T5-2 Example T5-1 Importing Geometry using a SolidWorks Geometry Translator The Abaqus/CAE Teaching Edition version 6.6 did not in general support geometry importation from CAD systems (an Expanded Teaching Edition of version 6.6 did). That is, it did not provide for the necessary geometry file translators. However, version 6.7EF or higher does support geometry file importation (e.g., from SolidWorks)....
