Start CATIA V5.

Select Tools>Options from the menu bar.

The Options dialog box appears.

Select the Analysis & Simulation category in the tree to the left, then click the Nonlinear and Thermal tab.

The complete list of options is as follows:

• Job Submission: These options provide the path to the installation directory where the Abaqus analysis product files used for running Abaqus jobs reside and the port number used for receiving messages from Abaqus jobs.

  For example, if your Abaqus installation resides in the directory C:\Abaqus\aba_version and the analysis executables reside in C:\Abaqus\aba_version\exec (where aba_version is the version-specific parent directory), the Solver Directory setting would be C:\Abaqus\aba_version. This option must be set before you can submit an Abaqus job.

  The default port number is 3421; however, you can specify any open port number. If the specified port is in use by another process, Abaqus for CATIA V5 will check the next 10 successive port numbers for an available port and display an informational message indicating that a different port has been chosen.

• Computation and Results Data: This option provides the path to the directory where Abaqus analysis jobs are actually run.

  Note:  You can also select Save Computation and Results Data to the Model directory if you want to specify that Abaqus analysis jobs be run and their output saved in the same location as the model files you use in the analysis.

• Temporary Data: This option provides the path to the scratch directory used for storing temporary data.

• User Subroutine Library: This option provides the path to the directory containing the compiled .dll file for all user subroutines that are referred to by the model. You should define the user subroutine library as solver_directory/code/bin, where solver_directory matches the Abaqus installation directory defined in the Job Submission options.

• Storage Manager: This option provides the path to the external editor used for viewing job text files from the Storage Manager (for example, xemacs or notepad).

• Solver Controls: The term overconstraint refers to multiple constraints acting on the same degree of freedom. By default, overconstraint checks are suppressed in each analysis step. If you toggle on Enable solver overconstraint checks, Abaqus will attempt to remove as many redundant constraints (constraints that are consistent with each other) as possible. When it is not possible to remove a redundant constraint or when an inconsistent overconstraint is detected, a detailed message is issued identifying the constraints contributing to the overconstraint. See Overconstraint checks in the Abaqus Constraints Guide for more information.

• Input File Writing: These options specify the format of the input file that is generated when you submit a job to Abaqus.

  By default, Abaqus for CATIA V5 combines all of the parts in the model into a single part and writes an input file with an assembly containing this single part. You can use this default behavior in conjunction with tools in the Advanced Meshing Tools workbench to merge coincident or adjacent nodes into a single node. Alternatively, you can toggle on As an assembly of separate parts to generate the input file as an assembly of separate part instances, where unconstrained nodes from each part instance are free to move relative to nodes from other part instances. When Abaqus for CATIA V5 writes the Abaqus input file, coincident nodes that are shared between separate part instances are treated as separate nodes that can move independently of each other. See Specifying the Input File Format for more information.

  Abaqus for CATIA V5 uses the CATIA sequential numbering scheme for all nodes and elements. However, third-party applications may allow you to replace the CATIA sequence numbers with “user numbers” for nodes and elements. By default, Abaqus for CATIA V5 replaces the sequence numbers if user numbers are available. You can toggle on Use only sequence number of nodes and elements to prevent the sequence numbers from being replaced.

  Note:  If user numbers are not applied to the entire model, there is a potential for conflicting node and element numbers. Selecting this option prevents any numbering conflicts from affecting the analysis.

• Abaqus Solver Units: This option specifies the units used for length, mass, time, and temperature when you write an Abaqus input file or import an Abaqus output database. You should use the Abaqus Solver Units option if you sometimes perform pre- and postprocessing tasks on the Abaqus input file or Abaqus output database, respectively, outside of Abaqus for CATIA V5.

  CATIA V5 always saves model data internally in the International System (SI) of units (meters, kilograms, seconds, and degrees kelvin), regardless of the units you choose to display. (To set the displayed units, select the Units tab from the Parameters & Measure category of options.) By default, the Abaqus Solver Units option is also set to SI units. If you change the solver units, Abaqus for CATIA V5 converts the model data into the selected units when you create an Abaqus input file or submit an analysis. Abaqus for CATIA V5 writes the solver units in the heading of the Abaqus input file when you create an input file or submit an analysis.When you import an Abaqus output database file, Abaqus for CATIA V5 converts the output database from the current solver units back into SI units for storage and displays your results using the selected CATIA units.
