Results is smaller than the analysis grids point + results interpretations #73

Hi @mostaphaRoudsari,

1.I am testing the honeybee sample 05_annual_radiation_gridbased with as inputs a solid surfaces instead of the saple rectangular surfaces. Everything work fine but when I increment the grid density i get the error below ( I have not changed the analysis grid during the calculation and the number of inputs _testSurfaces=_disFromSurface.

Is there something that I am missing?

"ERROR:

Length of the results is smaller than the analysis grids point count [892]. In case you have changed the analysis Grid you must re-calculate daylight/view matrix!

error message:

Traceback (most recent call last): File "", line 43, in ValueError: Length of the results is smaller than the analysis grids point count [892]. In case you have changed the analysis Grid you must re-calculate daylight/view matrix! "

  1. Resuts interpretation (I post it here because it may be only an error in my settings and not an issue). I tested a rectangular facade oriented to south while i was expecting consistent value along the facade some of the mesh has a lower value than what i would expect. result_issue result_issue_01

Thanks Andrea

Hi @andreameneg,

  1. When you change the grid density you're changing the number of test points and because of that you need to re-run the analysis. The way Honeybee is set-up is to re-read the results unless you force it to re-run. Set reuseDmtx to False so the analysis runs for the new test points.

  1. See this topic. Small difference between the values is expected. You can run the analysis with a higher quality if you want to get the exact results for all the test points facing the same direction.

I also suggest to post your questions on (http://discourse.ladybug.tools). That way more people can help you with your questions.
