The script reads integration point data for elbow elements from an output database to visualize one of the following:
The script creates either an ASCII file containing X–Y data or a new output database file that can be viewed using Abaqus/CAE. To use option 2, you must ensure that the integration point coordinates (COORD) are written to the output database. For option 1 the X-data are data for the distance around the circumference of the elbow element, measured along the middle surface, and the Y-data are data for the output variable. For option 2 the X–Y data are the current coordinates of the middle-surface integration points around the circumference of the elbow element, projected to a local coordinate system in the plane of the deformed cross-section. The origin of the local system coincides with the center of the cross-section; the plane of the deformed cross-section is defined as the plane that contains the center of the cross-section. You should specify the name of the output database during program execution. The script prompts for more information, depending on the option that was chosen; this information includes the following:
Before executing the script, run an analysis that creates an output database file containing the appropriate output. This analysis includes, for example, output for the elements and the integration point coordinates of the elements. Execute the script using the following command: abaqus python felbow.py <filename.odb> The script prompts for other information, such as the desired postprocessing option, part name, etc. The script processes the data and produces a text file or a new output database that contains the information required to visualize the elbow element results. Elastic-plastic collapse of a thin-walled elbow under in-plane bending and internal pressure contains several figures that can be created with the aid of this program. |
