5 phase simulation method

For the first two parts of 3 phase simulation, why we choose ‘glazingvmtx.rad’ rather than ‘glazing.rad’ as the receiver surface for the V matrix and the sender surface for the D matrix? Is it related to the material ‘glow’ ?

Yes, and also because it contains the directive for rfluxmtx (#@rflux… ) that hemispherical sampling is for a full klems basis (kf, 145x145).

@lee

In the direct sun coefficient simulation part, what object should replace the ‘blindsWithProxy.rad’ if there is just the double insulating window not the window with blinds?

It would just be the glass material and polygon then. The fifth phase would then be similar to the direct-sun part for the “DDS” workflow.

@lee

As for the ‘blindsWithProxy.rad’ , the material is BSDF and the geometry is the combination of the glazing and blind. How to make similar file if I have the XML file of the insulating window from the software WINDOW? What about the thickness of the material BSDF? The thickness of the insulating window is 24 mm, is it reasonable to create a file ‘glazing_bsdf.rad’ like this?

@Taoning_Wang1 , what do you think?

@lee

When generating the material map, why we choose ‘GlazingvmtxBlack.rad’ to make the window black? And ‘Map5Phase.oct’ and ‘Map3PhaseDirect.oct’ is not identical, which one is true?

It should be materialMap5Phase.oct and not materialMap3PhaseDirect.oct. These lines in the tutorial script and the corresponding Page 80 of the tutorial reference the incorrect octree.

@lee

Why we have to get the ‘illuminance sun coefficients for images’ and ‘luminance sun coefficients for images’ respectively and combine them together later by the material map?

The rationale for doing so is explained in this paper.
