Inconsistent crash without error log

asked 2023-04-26 05:39:00 -0600

updated 2023-04-26 10:50:11 -0600

hi

My simulation is crashing halfway through, and the error log is empty, completely blank. I'm using EnergyPlus 22.2. I've checked multiple times the IDF and I can't seem to find any reason causing this. I've tried with an original EPW and another one modified through Elements. Both crashed.

Please find attached the IDF and the epws. https://we.tl/t-twcYLtNGjU

has anyone experienced something similar? any help would be really appreciated.

kind regards, Olivier

I got the same message as @Denis Bourgeois. After fixing that (when not running using EP-Launch), by running ExpandObjects.exe and then changing expanded.idf to in.idf, the file ran successfully with these results. If you are running the file and not getting these results you may have a memory issue.

Failed to launch altogether, not halfway through. An excerpt of the generated "eplusout.err" file (when running the IDF with either EPW file):

** Severe  ** GroundHeatTransfer:* objects [...] not supported directly by EnergyPlus.
**   ~~~   ** You must run the ExpandObjects program on this input.

As mentioned elsewhere (e.g. here and here), you need to first run the Basement preprocessor program.
