Chapter 5: Solution • Total Strain • Elastic Strain • Thermal Strain • Creep Strain • Thermal Gradient • Thermal Flux • Electric Field • Electric Flux Density • Magnetic Field Intensity • Magnetic Flux Density • Magnetic Forces • Pressure Gradients • Body Temperatures • Densities for Topological Optimization Because the PGR file is constructed without resynchronizing the .db file, the following items will not provide valid data to the PGR file: • Sourc36 Elements • Super Elements • Circuit Elements 5.5.2. Selecting Information for the PGR File The information you choose in Solution will be stored in the PGR file. Although you can create or append a PGR file in POST1 (by accessing the .rst file), choosing the information during Solution will provide the greatest speed/accessibility benefits. You designate the PGR solution data by accessing the unabridged Solution menu (Main Menu> Solution> Unabridged). From the unabridged solution menu, you select Output Cntrls, and then PGR File. The following PGR File Options dialog box appears: 110 Release 13.0 - © SAS IP, Inc. All rights reserved. - Contains proprietary and confidential information of ANSYS, Inc. and its subsidiaries and affiliates.
Figure 5.2 PGR File Options From this panel, you can designate the location and the name of your PGR file, the type of data you wish to include in the file, the type of averaging scheme(s) for the data, and whether or not to include data from the interior portions of your model. You can change any of the items you wish to include in your PGR file up until the first solution. After you solve (even just one load step) you cannot make changes. See Appending to an Existing PGR File in POST1 (p. 170) for information on how to append your file after solution. The options available from the PGR File Options panel correspond to the PGWRITE and POUTRES commands, and to some extent, the AVRES command. You can access the following operations from the PGR File Options Panel : Write PGR file during solution - Checking this box creates the PGR file. If you are restarting a solution, you will overwrite the existing PGR file. PGR filename - From this location, you can provide a specific name for your PGR file and designate an alternate directory location to create it in. The default file name is Jobname.pgr, and the default location is the working directory of the current analysis. Select PGR result items - You use this list box to select the items you want to include in your PGR file. You can hold down the Ctrl key to select multiple items individually, drag your mouse across multiple select items, or use the Shift key to select the boundaries of inclusive lists. The following items can be included in a PGR file (the available items will change according to the context of your analysis): • Nodal Solution Data • Stress • Structural nonlinear data • Contact data (3-D only) • Total Strain • Elastic Strain Release 13.0 - © SAS IP, Inc.
