[Equest-users] GSHP simulation crashing

[Stephen Parker]

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.

Stephen: That happened to me and it took me awhile to play the rat-in-a-maze game until I discovered that it crashed when I tried to simulate a certain geology or grout (sand, wet or dry, I can’t remember) for the water-side of the system…weird. Good luck---

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,
