Importing Parts into Abaqus/CAE

There is more than one way to create geometry in Abaqus/CAE. The pre-processor (CAE) allows the user to create geometries, parts and assemblies, whether 1D, 2D or 3D. However very complex geometries could be time consuming using the pre-processer, and it is vastly easier using dedicated CAD software. 

Geometries created in CAD software e.g. CATIA V5 can be imported into Abaqus/CAE using the “Import” options.

Parts can be imported into Abaqus/CAE in the following formats:

  • ACIS SAT (.sat)
  • IGES (.igs, .iges)
  • VDA (.vda)
  • STEP (.stp, .step)
  • CATIA V4 (.model, .catdata, .exp)
  • CATIA V5 (.CATPart, .CATProduct)
  • Parasolid (.x_t, .x_b, .xmt)
  • ProE/NX Elysium Neutral (.enf)
  • Output Database (.odb)
  • Substructure (.sim)

 
It is important to note that not only individual parts can be imported. Among the imports available for Abaqus/CAE are the following:

  • Model (Imports a whole model for analysis, including material, mesh, etc.)
    • Abaqus/CAE Database (.cae)
    • Abaqus Input File (.inp, .pes)
    • Abaqus Output Database (.odb)
    • Nastran Input File (.bdf, .dat, .nas, .nastran, .blk, .bulk)
    • Ansys Input File (.cdb)
  • Sketches
    • ACIS SAT (.sat)
    • IGES (.igs, .iges)
    • STEP (.stp, .step)
    • AutoCAD DXF (.dxf)
  • Assemblies
    • Assembly Neutral (.eaf)
    • CATIA V4 (.model, .catdata, .exp)
    • Parasolid (.x_t, .x_b, .xmt)
    • ProE/NX Elysium Neutral (.enf)

 
To import a Part or a set of Parts into Abaqus/CAE, the following steps can be taken:

  1. Go to File > Import > Part

    The Name – Repair tab has naming options. If an assembly is being imported, this provides additional options for either combining or importing as individual parts.

    In the “Part Attributes” tab, Modeling Space and the part Type can be defined. For example, if the part is Axisymmetric, this would be a 2D surface, representing the cross section of a revolved solid.

    The Scale tab allows the user to bring the model in the desired units. Abaqus/CEA does not have units, so the values for any parameter or measure which are input into the software have to be consistent. If the CAD package where the geometry was created was in millimetres but the analysis is to be done in meters, then the model will need to be scaled by 0.001.
     
  5. Click OK
