Thanks for your help @Denis Bourgeois. As outlined in your previous instructions, we ran a measure in OpenStudio whic

Edited to provide answers for Denis:

OpenStudio Application version? 1.6.0+53c249a897 (SDK 3.6.1)

does the saved .osm file hold an instance of OS:Site:GroundTemperature:Undisturbed:KusudaAchenbach? No

if so, can you post the .osm excerpt? NA

might as well post the OS:GroundHeatExchanger:HorizontalTrench .osm definition: See below

Thanks!

I created an OpenStudio model with a horizontal ground heat exchanger, but OpenStudio isn’t allowing input of “Undisturbed Ground Temperature Model” in the object “OS:GroundHeatExchanger:HorizontalTrench”. The field is greyed-out and can’t be selected.

The model simulates properly (no crashing) when using default entries for a vertical ground field, but when I switch it for a horizontal ground field and simulate the model it crashes with the following message:

“[BOOST_ASSERT] <2> Assertion modelObject failed on line 175 of class openstudio::model::ModelObject __cdecl openstudio::model::detail::GroundHeatExchangerHorizontalTrench_Impl::undisturbedGroundTemperatureModel(void) const in file D:\OSN\src\model\GroundHeatExchangerHorizontalTrench.cpp.”

Based on this background, can somebody explain what might be wrong with my model to prevent it from simulating a horizontal GSHP field? Is there an input in OpenStudio that will allow me to select an “Undisturbed Ground Temperature Model”? Is the field supposed to be greyed-out?

Can OpenStudio simulate horizontal ground heat exchangers?

(There's a similar question from about 7 years ago--suggesting that there was a problem, but followed by discussion of the problem having been fixed. Perhaps the problem has been reintroduced?)

Thanks for the suggestion!

I have not been able to get PAT to run. I've tried two different computers, I've upgraded to the latest download, I've uninstalled, reinstalled, restarted the computer, etc. I have tried both my own model and measures and an example model and measures. In all cases, I get a "completed datapoint failure" message. I'm new to PAT, so it's possible I'm doing something stupid, but I'm not sure how to go about trouble-shooting this problem. Oh--the model and measures run without errors in OpenStudio.

This is very helpful. Thanks!

I am running multiple PAT runs. The set of design alternatives for each file is very similar, but the base OpenStudio file changes. I don't want to put all runs into a single PAT run. I've been using "save as" to create a new PAT file, and then I tweak the new file appropriately. "Save as" takes a long time--and I'm guessing I am duplicating more than I need to. Is there a quicker way to do this?

I have an OpenStudio Parametric Analysis Tool run that appears to run each measure combination successfully. However, when I hit "View Analysis" so I can download the results.csv file, I get the following error: "Executor error during find command: OperationFailed: Sort operation used more than the maximum 33554432 bytes of RAM. Add an index, or specify a smaller limit. (96)" Any clues?

Alternatively--is there a better way to match the very long string of characters identifying a run in the local results folder with the design alternative I've assigned? I've been pulling the long string of characters/design alternative pairing off the results.csv file.

Thanks!
