Openstudio Preview OSM issues related to "Face difference is self intersecting." How should I fix these errors?
I do not understand the error messages, therefore, I do not know how to solve the issue.
I have searched through unmet hours and the openstudio github, and did not find any posts with solutions.
Will these issues cause the simulation and results to be inaccurate?
Please let me know if there are other files or images needed?
I will post images of the error and model below.
It's hard to tell exactly what is wrong without the floorplan.json file. However, there do seem to be some problematic surfaces which would cause incorrect simulation results. Are you able to look at the 3D preview in the OpenStudio Application after converting this floorplan to OSM? Are there missing floors or other surfaces?
Yes. Although the errors appear, I can see the 3D preview. I have gone back to the model to eliminate some of the surfaces that are disconnected/have empty areas between spaces. I have filled in certain areas and tried correcting some of the spaces, but the error persists.
You might need to edit some of your spaces so their footprints are simple convex polygons. For example, you could divide that green corridor space into multiple, simpler spaces. When you do the zoning, you can assign all the spaces in the corridor into the same thermal zone which will have very similar simulation results to keeping the corridor as a single space.
