[TRNSYS-users] TRNSYS3D Rendering shadows question

[Lampros Karalis]

Dear All, 

 

I have to study a building which is located next to a quite large warehouse.

I did created the skp  and idf files  properly , and I also created the .eso
files as described in the tutorial

 

However when I select Rendering à by datavalue, the shadows from the near by
building is not displayed. 

 

(I have to note that when selecting Rendering à by surface, the shadows are
displayed properly, but this does not help be because it doesn’t present the
temperature values.)

 

Am I missing something? 

Is there a way to achieve the temperature presentation, with the shadow
influence of the nearby building?

 

 

Best Regards

Subject: TRNSYS3D plugin question

 

Dear All,

 

I am working with the latest version of the TRNSYS 3d plugin on windows XP
and using the trnsys 17.00019 version of the simulation Studio.

 

I already have sketched my building and defined the zones in it, as
described on the manual. 

The most common problems I have met so far have to do with some error
messages when I try to use the skp file. However I read Mr. ‘s Duffy note
that we should only use the idf file, and therefore I did not worry.

 

My main problem begun when I started drawing the shadow objects that affect
my building.  I did defined the objects as noted on the tutorial (version
June 2010) and on the Outliner Window I could see two Shading Object groups,
(one for the nearby building that affect mine and one for a second
construction that is attached to my building) Please see attached skp file.

 

When I saved and reopen the idf file, Outiner window showed 17 shading
objects (!) see attached idf file. Even though I believe that it
automatically created one object per surface, it is important to know

1.       Is this normal?

2.       Does this affect my calculations?

3.       Can I do something to make it behave properly?

4.       Why does outliner window of my skp,  even though it produces
errors, shows the shading objects properly?

 

Any help would be most appreciated, specially on questions #1, #2

 

Best Regards
