How to prepare geometry for Cyclops?

Hi Cyclops Team,

I am having trouble figuring out how to prepare my Scene Object meshes. All the tutorial files work properly on my system but when I try to create an analysis of my own, for example a Point in Time Daylight Analysis, I get absurd lux values of more than 10k+. My guess would be that this is happening because the mesh might have some tiny holes that are getting missed? The profile of the building does have degree 2 curves so maybe there is some issue in the meshing step.

Hi @Kyuubimode,

A few things.

  • I would recommend that you work in meters. That is the standard unit in EPW files.
  • The analysis points are directed down towards the floor. The direction should normally be orthogonal to the surface you’re analysing, meaning upwards in this case.
  • The analysis points are placed coplanar with the floor geometry. They should be moved slightly above the floor to avoid the risk of rays intersecting with the floor.

Also I don’t believe a 10k+ lux value is absurd in direct sunlight.

Sweet, thanks a lot! Completely missed the analysis points being in the wrong direction. Thanks a lot for your help.

I forgot to say that I meant 10k+ LUX everywhere in the building as opposed to just near the windows. I was just looking at the numerical bounds of the daylight analysis result to check if the analysis was working.
