OdbError –
TypeError – This function takes no keyword arguments.

minEnvelope()[source]¶

Retrieve the minimum value of an output variable over a number of fields.

Returns:¶

A sequence of two fieldOutput objects. The first fieldOutput object contains the minimum value. The second fieldOutput object contains the index of the field containing the minimum value. The index follows the order in which fields are positioned in the list of fieldOutput objects provided as the argument to the function.

Return type:¶

Raises:¶

OdbError –
TypeError – This function takes no keyword arguments.

openOdb(path, readOnly=0, readInternalSets=0)[source]¶

This method opens an existing output database (.odb) file and creates a new Odb object. You typically execute this method outside of Abaqus/CAE when, in most cases, only one output database is open at any time. For example:

import odbAccess
shockLoadOdb = odbAccess.openOdb(path='myOdb.odb')

Note

Check OdbCommands.openOdb on help.3ds.com/2024.

Parameters:¶

path¶: A String specifying the path to an existing output database (.odb) file.
readOnly=0¶: A Boolean specifying whether the file will permit only read access or both read and write access. The initial value is False, indicating that both read and write access will be permitted.
readInternalSets=0¶: A Boolean specifying whether the file will permit access to sets specified as Internal on the database. The initial value is False, indicating that internal sets will not be read.

Returns:¶

An Odb object.

Return type:¶

Odb

Raises:¶

OdbError – 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 –
opened. – If the output database was generated by a newer release of Abaqus, and the installation of Abaqus needs upgrading.

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')

Note

Check OdbCommands.upgradeOdb on help.3ds.com/2024.

Parameters:¶

existingOdbPath¶: An String specifying the path to the file containing the output database to be upgraded.
upgradedOdbPath¶: An String specifying the path to the file that will contain the upgraded output database.

Raises:¶

OdbError – If the output database upgrade fails.
