Mfix solver has terminated unexpectly

Hello, after I added the fluid species to the case, the solver crashed in the calculation (it can run when setting the type), may I ask what might be the cause?

Please attach your files (main menu > create bug report) so someone can take a look.

What do you mean by

?

The stl file 1.stl is missing. It says it’s locationis D:\\Mch\\mfix\\1.stl. The stl file should be copied to the project directory. Is mfix the name of your project directory?

1.STL (684 Bytes)

Sorry, an message error occurred. What I want to say is that the case will work without setting the fluid species.
