wrong results in Daysim

Hi all;
I´m been using Daysim for a few weeks now and I´m getting some strange
results that does´t make sence to me. I´m using ecotect from wicht I export
to daysim and when it´s finish I import the results into ecotect again.
I receiveng 0% DA near a window and 100% inside a close space with no
windows. This seems to happen only when I create a grid inside a space with
a lot of internal subdivisions like walls and pillars. Also seems to happen
only when the grid covers multiple orientations. When is only one (north,
south, etc) this does´n happen either.
Does anyone else experience this using daysim true ecotect???
Anyone knows the problem?

Dear Alejandro,

Daysim/Radiance does not distinguish between simple and simple geometries. (Of course, if a sensor is located in a wall it should yield zero lighting unless your ambient accuracy value is set too high.) My suspicion is that you are reading in a wrong set of sensor points into Ecotect. Ecotect has no intrinsic way of making sure that a DA file actually goes with your current sensor grind. It is up to you to make sure that the two are consistent.
