Re: [TRNSYS-users] Error Shading matrix



This error occurs when a mismatch between shading matrix and radiation input for this surface is detected.

The radiation matrix contains a marker when the sun is behind the surface, thus no direct solar radiation can strike the surface.

If this is the case, but radiation input for direct radiation is greater than zero the error message is displayed.

 

This is likely to happen if the azimuth / slope of the orientation is different from the azimuth / slope of the surface
in the geometrical model in Trnsys3D.

 

Did you modify azimuth angles by rotation or so?

 

If you still have trouble a deeper look into your project is required.

Did you contact your TRNSYS distributor?

Betreff: [TRNSYS-users] Error Shading matrix

 

Hi all!

 

I'm having a problem with the church I'm currently modeling in the Sketchup plugin.

I've succeeded in creating a model that is convex and that will not generate a stack overflow when I simulate it. When I simulate one day, I have no problems, yet when I try to simulate over a longer period I get the following error:

 

Error Shading matrix. Direct solar radiation surface   2 with orientation  11 is not zero.

 

What does this mean?

 

Any advice would be very helpfull
