[TRNSYS-users] TRNSYS crashes after several runs

Dear David,

I have tried deleting all the devices that generate output files, as you
suggested, but the model still crashes at second run.
I think Simulation Studio does not manage to start TRNExe, because as soon
as I press the "Run" button the window turns white and closes (as usually
do programs in Windows) with a standard message "A problem caused the
program to stop working correctly. Windows will close the program and
notify you if a solution is available.".

Maybe this is a Windows problem or a compatibility problem? But this is not
happening when I delete all the files except the .tpf and the .b17 (the
.dck, .bld, .log, .inf, etc).
As far as I know none of these generated files (the .dck, .bld, .log, .inf,
etc) are needed to start the simulation, but they appear to be the reason
of the crash.

Regards,
Victor
