[TRNSYS-users] trnbuild error in generating the shading/insolation matrix

Tue Mar 22 01:16:50 PDT 2011

Dear Stefano,

I apologize for the delay. I was deeply involved with project worked and
… .

The problem is the “VirtualSurface” between 

CHURCH_NORTH and MAIN_CHURCH

CHURCH_SOUTH and MAIN_CHURCH

A “VirtualSurface” is very special. It is drawn in order to close a
volume, but it isn’t imported as heat transfer surface and doesn’t
appear in TRNBuild anymore.

The insolation matrix calculation uses the Data of TRNbuild and since
the virtual surfaces aren’t there the error appears. The
“VirtualSurface” in the 3D mode 

should be used in conjunction with multi-airnode zones only.

I solved the problem by the changing the “VirtualSurface” into an
“adjacent wall” in the zones (see attachement).

If you need to transfer the radiation from CHURCH_NORTH into MAIN_CHURCH
you can place a window on the adjacent wall.

This window might be the “no window” with a solar transmission of 100 %.

Cheers,

Marion

Dear Marion,

I have managed to solve the software problem for the generation of the
shading/insulation matrix.

The fact is that when I let the radiation model as standard the matrix
generator give me no errors; on the contrary, with the detailed model I
get one error readable in the log file.

Do you have any idea?

Thanks a lot

Stefano

Dear Stefano, 

iI imported your IDF to TRNbuild and created a shading matrix without
problems. 

Did you turn on the detailed model for beam radiation of a zone? Which
one? 

Best, 

Marion

Dear Stefano, 

if you send me the IDF / b17 file I can have a look at it. 

Cheers,

Dear users, 

I am facing the following crashing of TRNbuild when generating the
shading/insolation matrix 

Pleae find a screenshot of the error in the attached jpg! 

Thanks for your help and suggestion! 

Stefano
