[esp-r] Re: shading & insolation analysis with new *.geo format

[Jon Hand]

The traditional approach to doing automatic shading and insolation
calculation was to assume all applicable surfaces were included for
shading and insolation. If you wanted to be more specific you had
to re-calculate with a manual selection.

There is an additional dialogue in the project manager
when working with the new geometry format that allows
you to pre-specify which surfaces to include in shading
as well as which insolation sources you want. Ish will
then use these directives.

This issue described probably is related to this dialog
in the project manager - prj is expecting you to give
an opinion prior to running the shading calculations.
The automatic translation to the new format probably
does not fill in these values unless a shading analysis
has already been done.

If after upgrading the geometry format your opinion
about shading and insolation is defined then ish
should run without that warning. 

It should be possible to extend the logic to check
as the user is requesting a shading analysis for
these directives.

Subject: [esp-r]  shading & insolation analysis with new *.geo format
 
Dear all,

 

did anyone tried the shading & insolation analysis with the new *.geo format?

 

My model is a simple box with one glazing (exterior). I create this with vs. 3412 and get the old *.geo format. The shading insolation was no problem. But when I change into the new format style, I get the message "No insolation source surface found!".

 

This problem appears when I create the geometry, change into the new format and try the insolation. 

If I make the geometry, do insolation, change into the new geometry style and do the insolation again, then the insolation is ok. It depends on the sequence!

 

 

Old *.geo format

#  X co-ord, Y co-ord, Z co-ord

      0.00000     0.00000     0.00000  # vert   1

      5.00000     0.00000     0.00000  # vert   2

      5.00000     3.00000     0.00000  # vert   3

....

 

 

new *.geo format

# tag, X co-ord, Y co-ord, Z co-ord

*vertex,0.00000,0.00000,0.00000  #   1

*vertex,5.00000,0.00000,0.00000  #   2

*vertex,5.00000,3.00000,0.00000  #   3

....
