Closed Issue # 2181

[sprankleray]

Issue #2181 identifies a bug with O2 limited conditions that was fixed in a post dated the day before V7.7.5 was released. Can you please verify the bug fix was included in V7.7.5?

CFAST 7.7.5 was released on May 4, 2025

This bug was fixed on May 26, 2025, so it was not included in the release.

Can you suggest a workaround that doesn't involve modifying the code as you have done? Does this suggest we can't rely on model results where O2 limiting conditions exist? Can you more clearly define which output parameters are affected by this bug?

[mcgratta]

I did not make the fix, but it is probably a good time to issue a maintenance release of CFAST.

[sprankleray]

We have used CFAST models that show vitiated conditions in several very important calculations. We need to be able to define the scope of this issue (specific output affected) in our calculations in a timely manner. Or, if there's a new release issued very soon, we can run the new version and compare results. Do you have an idea how soon you can issue the maintenance release?

[mcgratta]

We should be able to do it this week.

Excellent!
Thank you very much.

New release is out.
