3.3 Incorporation of the output database join process into the driver

Products: ABAQUS/Standard  ABAQUS/Explicit  

Benefits: You can now use ABAQUS execution procedures to join output databases generated from the original and restart runs of an analysis or to combine the output databases generated from a substructure analysis. This functionality was available in earlier releases in the example programs odbjoin.c and substructurecombine.c, but this enhancement improves the accuracy and performance of these operations and makes them easier to access.

Description: The abaqus restartjoin utility appends an output database (.odb) file produced by a restart analysis of a model to the output database produced by the original analysis of that model. Combining the original and restart output database files into a single file enables you to examine all of the output data for the analysis in ABAQUS/CAE.

You can append output database files from analyses that restart between steps and from analyses that restart in the middle of a step. For an analysis that stops and restarts between steps, ABAQUS simply appends the output from the new steps to the output from the existing steps of the original analysis. For an analysis that stops and restarts in the middle of a step, the original and restart analyses overlap because the restart analysis resumes at the beginning of the interrupted step. In this case the abaqus restartjoin utility retains the results for any completed steps in the original analysis but replaces the results for the interrupted step with the output data produced by the restart analysis.

The abaqus substructurecombine utility combines the model and results data produced by two of a model's substructures into a single output database (.odb) file. By combining all of a model's substructure analysis output database files, you can display all of the data produced by a substructure analysis in ABAQUS/CAE. ABAQUS combines output data by adding the contents of the second file you specify (the copy output database) directly into the first file you specify (the base output database). Because this process changes the base output database, consider backing up your data before using this utility.

If your model includes more than two substructures, you must run the abaqus substructurecombine utility multiple times to create a single output database from an analysis with more than two substructures. Combine data from two of the substructures first, then repeat the operation to combine the resulting output database file with data from each remaining substructure.
