[TRNSYS-users] Errors of temperature divergence and convergence

[Marion Hiller]

Pauline,

No, I don’t think you need a compiler.
I have the value that your building is getting a “bad” value as input and as a consequence
Type 56 can’t calculate correct temperatures and outputs NaN instead.


I recommend to start replacing one user input of Type 56 after the other by a constant value
and check if the simulation runs and reasonable temperatures are calculated..
For setting an input value of Type 56 to a constant value simply disconnect  the input and define a “good” value as initial value.

Hi, so sorry to fill your boxes with my emails but in my search for explanations for errors described in my previous mails, I just realize that they can come from the fact that my TRNBUILD temperatures outputs are equivalent to NaN (Not a number).
I understood that to find the source of the issue we had to work with a compiler.
Unfortunately I do not control that.
Can you give me ideas of sources of errors like or instructions to avoid these problems?

Thanks a lot again.
Hoping you can give me some clues.
Best Regards.

Hi,

Following my mistakes difference of temperature (see previous mail, and although trying to change the type of glazing, values ​​of convection, frame percentage...), I wanted to test the simulation without window: new errors were occurred, and the calculation appeared infinitely long (only 20 hours simulated on 8760 during 4 mins), with the following statement. These units correspond to the type 87 (unit 23 = TRNBUILD) and 93 (31/32/33 = Input value recall) as used in previous projects without any problem. I have absolutely no idea of solution to resolve these errors. Do you have any clues for me?

Hi,

on my current project, I have a blocking problem that seems to come from windows (please find below the problem statement). But the windows used are identical to those I use on other projects without ever having this error.. Do you know where it can come from?

Thanks a lot for your help.

Best regards.

Pauline
