Abaqus Output Database

The Python ODB API commands are used to read and write data from an output database (.odb) file. The path to the Odb object can be via the session.odbs repository or via a variable. In this chapter the Access and Path statements refer to a variable called odb that represents an existing Odb object.

It is important to note the difference with MeshElement object of MDB where the connectivity is node indices instead of node labels.

getNormal(faceIndex, stepName='', frameValue='', match=CLOSEST)[source]

This method returns the normal direction for the element face.

Added in version 2017: The getNormal method was added.

Parameters:

Returns:

A tuple of 3 floats representing the unit normal vector. If the element face is collapsed such that a normal cannot be computed, a zero-length vector is returned.

Raises:

This method opens an existing output database (.odb) file and creates a new Odb object. This method is accessed only via the session object inside Abaqus/CAE and adds the new Odb object to the session.odbs repository. This method allows you to open multiple output databases at the same time and to use the repository key to specify a particular output database. For example:

import visualization
session.openOdb(name='myOdb', path='stress.odb', readOnly=True)
Parameters:
name

A String specifying the repository key. If the name is not the same as the path to the output database (.odb) file, the path must be specified as well. Additionally, to support backwards compatibility of the interface, if the name parameter is omitted, the path and name will be presumed to be the same.

path=''

A String specifying the path to an existing output database (.odb) file.

readOnly=0

Returns:

An Odb object.

Return type:

Odb

Raises:
  • OdbError – The database is from a previous release of Abaqus, If the output database was generated by a previous release of Abaqus and needs upgrading, Run abaqus upgrade -job <newFilename> -odb <oldFileName> to upgrade it.

  • OdbError – Abaqus installation must be upgraded before this output database can be opened, If the output database was generated by a newer release of Abaqus, and the installation of Abaqus needs upgrading.

  • AbaqusError – If the file is not a valid database.

upgradeOdb(existingOdbPath, upgradedOdbPath)[source]

This method upgrades an existing Odb object to the current release and writes the upgraded version of the Odb object to a file. In addition, Abaqus/CAE writes information about the status of the upgrade to a log (.log) file. You can access this method using either of the following techniques:

  • From a script running outside Abaqus/CAE. For example:

    import odbAccess
    odbAccess.upgradeOdb(existingOdbPath='oldOdb', upgradedOdbPath='upgradedOdb')
    
  • From the session object in Abaqus/CAE. For example:

    import visualization
    session.upgradeOdb(existingOdbPath='oldOdb', upgradedOdbPath='upgradedOdb')
    
Parameters:
existingOdbPath

An String specifying the path to the file containing the output database to be upgraded.

An String specifying the path to the file that will contain the upgraded output database.

Raises:

OdbError – If the output database upgrade fails.
