Vent Open/Close Criterion Table input error

[Joel Lederfind]

Hello,

I have encountered a potential issue with time-based vent openings.  This issue appears in both CFAST 7.7.1 and 7.6.0 (which I was running comparisons against) and occurs with a single or multiple compartment-to-compartment vents.

It seems that if only one Open/Close Criterion Table entry is entered in using the CEdit GUI, the program doesn’t factor the input into the calculation and doesn’t save the input to the .in file.

I can get the input to be reflected in the model and saved in the .in file by duplicating the desired value into the Open/Close Criterion Table (i.e. two identical rows for time and opening fraction). 

Also, if I manually open the .in file in a text editor and enter in just one table entry, the model will run correctly and save the input in the .in file. 

I could not find text in the user’s manual or technical reference to indicate duplicate entries are required.

Any help is appreciated,

Joel Lederfind

It should work in CEdit though we’ve had problems in the past. We’ll take a look.
