[Radiance-general] 答复: Example 2 of three-phase method

[Wang Clarence]

Hi Greg,

I am using "The Three-Phase Method / Five-Phase for Simulating Complex Fenestration with Radiance" by A McNeil, LBNL.

Best,

Clarence

Hi Clarence,

Which tutorial are you using?  A few of the programs have changed slightly, and we generally recommend rfluxmtx over rcontrib for most calculations, as it is much simpler to use and therefore less error-prone.  You should use the new tutorial by Sarith, which was just recently posted to our website:

        https://www.radiance-online.org/learning/tutorials/matrix-based-methods

This is an advanced tutorial, but it starts with the basics and quickly moves through each of the methods.  There is also an associated set of input files here:

Best,
-Greg
