MISC options for EVAC in FDS 6.7.5 #8707

Closed scireNam closed 4 years ago

scireNam commented 4 years ago

Hi everyone. I would like to report that since FDS 6.7.5, maybe was introduced an error in starting a simulation with these 2 parameters in MISC namelist: EVAC_TIME_ITERATIONS and EVAC_PRESSUREITERATIONS, normally 50 by default. If written in &MISC will cause FDS to throw following error: ERROR: Input line 8 is not formatted properly; NAMELIST: MISC_

Previous versions work perfectly. Bye.

@scireNam Can you upload a small inputfile so we can reproduce the problem?

With this example (issue8707.fds), I can't reproduce your problem.

Can you show your &MISC line?

I'm sorry, but for unexpected reasons my script wrote a tab after namelist name, this lead to Error : not formatted properly. So no problem with that parameters, but i didn't know that a tabulation "\t" could lead to this format error:

Thanks for the feedback.

See the User Guide for details (section 5.2):

Parameters within a namelist record can be separated by either commas, spaces, or line breaks. It is recommended that you use commas or line breaks, and never use tab stops because they are not explicitly defined in the namelist data structure.

@scireNam Can you close this issue?
