GSHP simulation crashing

Hello All,

I have just modeled a building with a ground source heat pump for the first time and I have been having some issues to get it running properly. When I attempt to simulate the building performance, the model gets about 18% into its simulation at which point it attempts to simulate the affects of the HVAC system and then eQuest can go no further and crashes. To make sure the crash was not due to any other area of the model I changed to HVAC system to another type and it is able to simulate with no problems. Has anyone had this problem before or does anybody have any advice in regards to troubleshooting this problem?

Thanks,

Stephen Parker

Stephen-

I would recommend looking at the sim file for the project that crashed. Try
to determine where the sim file stopped and it should give you an idea of
what is crashing the model. If you are having trouble, email the sim file
and I will try to determine for you.

Thank you Craig,

It turns out that the problem was infact the grout and ground material that I had chosen which was silt. I attempted other soils like sand and I also was receiving the same problems. Finally when I switched to clay and saturated gravel, my problem was solved and the model was able to simulate.

Regards,
