[TRNSYS-users] TRNSYS crashes after several runs

[David BRADLEY via TRNSYS-users]

Victor,

   I have never run into something like this before. It is a little odd 
that it is the Simulation Studio crashing; the Studio doesn't really do 
anything when the simulation is progressing. Once a simulation is 
launched the Studio is idle. Also, when the Studio crashes, does TRNExe 
continue to run? The two aren't linked in any way so if one crashes the 
other ought to continue on.

   My only guess is that there is some output file that is accumulating 
from run to run. It is possible to set some of the printer components so 
that they append to an existing file instead of overwriting the file on 
each new run (for example Type25 parameter 7). Unless there is some 
reason to keep all the results in a single file, you can select the 
"overwrite" option. One easy way to check if the problem is one of the 
printers would be to make some consecutive runs after temporarily 
deleting all the devices that write to output files.

kind regards,

  David
