How to use subprocess to get multiple data outputs in desired folder?

[3SG14]

HI,

I am using subprocess to automate my Trnsys simulation for multiple inputs.

The problem I am having is each run should produce multiple results which its not producing? it moves to next run after giving me the first output for one objective (leaves others without showing any error and moves on).

Another issue: I have is that I want to store the results in folders(being created by python)for each and numbered for that run. So that I can avoid sorting them at the end of the process (having to avoid doing it manually).

my code is like this:

You don't really need to keep the modified deck open. You just need to write it and then complete the writes so that other processes can read it. So doing all that work in the with on line 48 seems wrong. You should exit that context immediately.

I have no idea what is meant by the multiple results. Can you have it just try to do one and then debug if it's giving you the correct results? If it is not doing so, provide more details and we can suggest what might be wrong.
