Hello Marshall,
maybe you have to save your project in an folder on drive C:\.
If you run your simulation from another participated drive (e.g.
D:\) or from an server-drive, I guess there are problems with the
maxheatload-calculation.
Kind regards, Daniel
Mit freundlichen Grüßen

Betreff: [TRNSYS-users] Max heat load calculation
Hello
TRNSYS users,
I have two questions:
1.
I am trying to use the "Max heat load calculation" feature in
TRNBUILD. Everything appears to work fine until the last stage where a
window appears displaying "Calculation Terminated" and I have to
choose "No" or "Run TRNSYS". I click the "Run
TRNSYS" button and then I get an error that says "File C:\Program
does not exist". I have checked and rechecked the directories under
the OPTIONS \ SETTINGS menu and my file directory for TRNSYS is correct.
The folder where I have my TYPE 56 shows that maxheatload files (.b16, .bld,
.d16) have been created.
What is the problem? Is there another way to set up the simulation?
2.
I am using the American library for my walls, layers, and windows in
TRNBUILD. I am curious to know how the conductivity for layers are
calculated. Say I want to use R-13 insulation, what would be the
corresponding conductivity? Does R-13 already exist in the library?
When I try converting from English units (R-13 = 13 ft^2 F h / BTU) to SI units
and inverting to obtain the U value I am left with an extra meter in the
denomonator (ie. kJ/(h k m^2)). Does TRNBUILD use some standard length to
eliminate a meter unit?
Thanks,
Marshall
