Workbench or one of the components may crash such that restart files are available but they are not recognized or populated in the Workbench project.
See Recovering from a Workbench Crash for the steps needed to recover a coupled analysis after a Workbench crash. You will also need the information below about Mechanical, as well as information specific to the other participant systems connected to System Coupling. For other participant systems connected to your System Coupling system, see Supported Coupling Participants for System Coupling in Workbench for a list of supported systems and references to their corresponding documentation regarding restarts.
The result files from the run that crashed may reside in either the system’s solution folder or in the _ProjectScratch directory. The _ProjectScratch directory is a temporary directory used by the Mechanical APDL solver. This directory contains the latest structural results and restart points written during the System Coupling run before Workbench crashed. Mechanical will need to read these file to recover the project using the steps below.
Note that the .backup directory contains the original version of any files which have been modified since the last save. These files are useful to recover the last saved state, but they are not useful for restarting your analysis.
To recover Mechanical's restart point after a workbench crash:
In the Project Schematic, double-click Mechanical's Setup cell. In the Mechanical interface, select the Solution entry from the tree.
From the Solution Context tab, select the Read Result Files option from the Tools group.
Browse to the location of the result files (which may be the systems solution directory or the _ProjectScratch directory) and select file.rst. Uncombined result files from a distributed-memory parallel solution can also be used instead of a single combined result file. In order to use the uncombined result files, the result file chosen must be file0.rst. Mechanical will now patch itself into a state consistent with the results files, with restarts points (if they were written) available for selection in Mechanical.
Select the restart point in Mechanical as in Specifying a Restart Point in Mechanical above.
Once you have selected Mechanical's restart point, in the Project Schematic, right-click Mechanical's Setup cell and select Update.
