Issue with results from 'Real time radiation Analysis' and grid size

My first problem is that, even though I set the same gridSize, there are much more test points for the complicated geometry (see picture) which leads to a quite high computation time. Why is that?

See this:

None Uniform Grid

Just for the reference here is how I would generate the uniform grid inside Grasshopper without using any plugins. uniform_grid.gh (26.1 KB) [image]

Second: After summing up all the values from the radiationResult from the ‘real time radiation analysis’ I end up having different results that the totalRadiation from the ‘Radiation analysis’ component, for the complicated geometry! For the simple geometry, it works well. (see second picture). I can’t understand it. Is it a bug?

For comparison you have to multiply the values with face area. The total radiation is kWh not kWh/m2. See here:

Measuring units of the Radiation Analysis outputs

This is a reply to a questions from Jacob (and Abraham): “…****which measuring unit does your radiation component output?” There are two different outputs that has two different measuring units: radiationResult is the amount of radiation for each test point in [kWh/m2] Note: each test point is the center of a mesh face and the number represents the amount of radiation per m2 of that mesh face. totalRadiation is radiationResult for each point [kWh/m2] * area of the face [m2] so it is in [kWh…
