Hi

I am using eppy to run a series of premade IDF files. I have used the code segment described in "Running in parallel processes using Generators." in the eppy documentation. The code segment works perfectly for smaller series of IDF files, but I start getting errors, then I add up to 10000 plus IDF files in the queue. My error right now:

Program Version,EnergyPlus, Version 8.9.0-40101eaafd, YMD=2022.07.11 15:00,
** Severe  ** <root> - Missing required property 'GlobalGeometryRules'.
**  Fatal  ** Errors occurred on processing input file. Preceding condition(s) cause termination.
...Summary of Errors that led to program termination:
..... Reference severe error count=1
..... Last severe error=<root> - Missing required property 'GlobalGeometryRules'.
************* Warning:  Node connection errors not checked - most system input has not been read (see previous warning).
************* Fatal error -- final processing.  Program exited before simulations began.  See previous error messages.

But the GlobalGeometryRules are in the IDF files for the given file. Therefore I am inclined to believe the error is occurring. Then I run many IDF files (10000+). Therefore I would be interested if anyone knew how to catch these errors in the Eppy foundation before it crashes my program.
