CATIA - ELFINI STRUCTURAL ANALYSIS 2 Product (EST)

General Issues

Multi Processing Capabilities (Windows only)
  •  If the HOME environment variable is defined, it must contain an existing and writable directory path. Otherwise you will have the following error message:
    Error in xcoexe/xcocall, IER = -1
  • If the HOME environment variable is not defined, the default temporary CATIA path is automatically used.
Computed Masses and External Storage Clean-up Once you have cleared computation data using the External Storage Clean-up command, computed masses are automatically re-computed in the following cases:
  • Generating images on computed masses.
  • Activating images on computed masses.
  • Creating inertia sensors.
  • Opening a document which contains at least one activated image on computed masses.

Those operations lead to the creation of a CATAnalysisComputations file which needs to be saved.

Composite Properties
  • The composite document may be modified the first time you launch a Mesh Only computation on an analysis document containing an imported composite material defined by plies.
  • The analysis results are incorrect in the following cases:

    Workaround:

  • The previous design constraints are also valid for composite materials defined by plies:
    • Do not use a surface join as ply group support.
    • Use a simple and closed contour as ply contour.
  • When you apply successively an imported composite material defined by zones on a mesh part, then an imported composite material defined by plies on another mesh part, the computation may not be launched.
  • Post-processing and composite:
    • Zone approach: the values of stress images in Average iso mode are incorrect for all the nodes common to different composite zones. The results are correct for the internal nodes belonging to a same zone.
    • Ply approach: the values of stress images in Average iso mode are potentially incorrect because the number and the order of the layers may vary from an element to an other.

    Generally, it is strongly recommended to use the Discontinuous iso mode for the images belonging to the stress physical type in a composite context.
