The relation between radiation results and the geometry

Hey guys,

I use the Ladybug Radiation Analysis component and I get the radiation results(not the total result), it is a series of numbers, also the radiation is plotted on the geometry, but how can I find out which result corresponds to which mesh(or which part) of the analysis radiation?

Thanks in advance,



Hi Zhonghao,

You can deconstruct mesh on your analysis mesh and iterate over the faces. I believe that HB will assign values in the same order as the mesh face order.

Of course some times GH’s ordering is a bit weird and I’m having also issues with this in cases where I want everything to follow a specific direction, e.g. x1y1, x2y1, x3y1, …, xny1, x1y2, x2y2, x3y2, …, where x, y are the length and width of the mesh.

I wonder if Mostapha/Chris have an idea on how we can rearrange this with native GH or how we can have HB manually setting the order in this structured way.

Kind regards,


In addition to Theodoros’s reply, you can also show on screen the results besides each surface.

How can I show the results on each surface?

Is the component also from Ladybug?Sorry, I am quite new at it .


hey, Theodore,

really thanks for your reply.

I will try it .

See attached example.
