I am calculating a two-phase water vapor flow problem in an open channel, using the VOF model. The error "BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES" is accompanied by "The fl process could not be. This error occurred after I had calculated many steps. After it appeared, all the buttons on the fluent interface could not be used. After I restarted the calculation, the same error was displayed again. How to solve it? I used 2022R1

Once this error is thrown, your Fluent session will be corrupted and will need to start a new one.

Does the error always occur at the same iteration? Try to see what happens with your solution before this error is thrown.

Hello, many error files were generated after an error occurred。Other files contain the following information: Abnormal Exit! How to solve？Even if I turn it back on, it's still a repetitive error that can't be calculated.The content of flunt-0-error is as follows:

The fluent-n-error files are error logs for each CPU used. 

For the original question, does this error always occur at the same iteration?

[Yiqing zhang]

These errors arise when the case is opened. After successfully completing calculations on one computer, upon transitioning to another computer to continue the computation, the issue is encountered upon opening the case. However, other cases listed on this computer do not exhibit this problem.

[Federico]

Are you using the same version between machines?

The first screenshot you shared suggests that the issue does not arise when opening the case. The simulation is running.

[Yiqing zhang]

I previously performed calculations using the 2021R1 version of Fluent. Subsequently, I attempted to use either the 2022R1 or 2023R1 versions of Fluent, but encountered issues as neither of these versions could be opened. Is it possible that this problem arises from the fact that I initially used a computer with an AMD processor and later switched to a computer with an Intel processor?The error that appeared in the first screenshot has been resolved. This is the second occurrence, happening when I transferred the calculations to another computer to continue the process.

[Federico]

That is possible. I suggest you make a new dedicated post for this issue, since the original problem is resolved.
