is their any Code for just 1 tank?

Hello
I wanted to analyze just one tank which has hydrogen in it ( no transfer line just one tank). Is their any code on this. Could you help me on this. I tried to edit the available code but nope getting errors and I am beginner in MATLAB which makes it worst.

Thanks for your time .

The issue does not identify a MATLAB file, test, or entry point, and the existing code is only described as a transfer simulation. First clarify the intended single-tank behavior and the errors encountered when editing the available code. Done would require an agreed scope and a reproducible single-tank analysis with verified results.
