Hi, everyone. I met this error while running. I would like to consult you about the possible cause of this and what I need to modify to solve it.Looking forward to your answer!

Hi. Running the job here did not lead to ‘NaN detected’. But it failed to converge (DT < DT_MIN).

Note the large number of warnings.

I’m seeing a large number of this warning:

Velocity exceeds limit:   100.00

To change the limit, adjust the scale factor MAX_INLET_VEL_FAC.

and this message:

The sum of mass fractions is not equal to one.

Note that you can scroll through the messages with the arrow and TAB keys.

The MAX_INLET_VEL_FAC message has been discussed here before, it most often is due to poor mesh quality. I suggest searching the forum for MAX_INLET_VEL_FAC.

Okay. Thank you very much.
