OpenStudio Intersection Error

asked 3 years ago

Hello,

I just want to ask if I can ignore all the errors ("Initial area of surface does not equal post intersection area") in OpenStudio? Because I cannot find a way to come around those no matter how hard I tried to execute.

Recently some logging was added to API output for methods that alter geometry for diagnostic purposes. Most users shouldn't see this unless they are looking at raw output. Generally the change in area should be very small (well under 1%). If you see a larger delta please post an issue at the OpenStudio repo, or in the repo for the measure you are using that sees this. In either case sharing a pre-intersected model will be helpful for us to replicate the issue.

Can I ask what do you mean by "the change in area" and the "pre-intersected model"?

The delta between the area of a single surface prior to intersection versus the combined area of multiple surfaces that result after intersection. The result is sometimes is a very small non-zero number, even though it ideally would be zero.

I didn't notice any deltas because I drew each floor based on the previous one. Yet, the loggings appeared after I merged the model in FloorSpaceJS. Is there a way that I can send anyone the osm file to see the issue?
