Dynamic change of fire simulation parameters about cfast HOT 6 CLOSED

It is not possilbe to stop a CFAST run, change the inputs, and then rerun.

Simply setting the door opening and closing times in the cfast.in input file will not solve the problem because our program works in such a way that only on the basis of the resulting data from CFAST it is determined where people will move in the building and therefore which doors will be open/closed in the next seconds of simulation. The temperature of the layers has no effect on the opening or closing of the door.

We are interested in adding functionality in CFAST to stop simulations, change input data, and resume simulations. We have programmers on our team who could take care of this because we need this feature. Is there anyone among you who is a developer or has experience in the CFAST project and could possibly help us and tell us where we can try to modify the code to add such functionality?

Thank you for your help. Your solution will be effective, but will result in a large number of CFAST simulations. In our software, people's reaction times are randomized according to probability distributions. Additionally, a person passing through the door may close it (with a certain probability). The above means that in a long simulation where many people are leaving the building, you may find that people will frequently pass through doors, closing them and opening them. It will be necessary to count several dozen, several hundred or several thousand CFAST simulations

if CFAST had a function to stop the simulation, change parameters, and resume the simulation, only one simulation would count.

Anyway, thank you for your help. If your solution is not sufficient for us in the future, we will look for another solution

If you want to modify CFAST, the source code is available from this repository. The input_namelist.f90 file contains the input processing. You can use that to see what variables are being set when you read in a vent that changes state at some time and then trace those variables through the code.
