When I was running this reactor, the pulse frequency was 6 Hz, the average gas velocity was 1.4 m/s, and it could operate with low amplitude without any errors. However, when I was running at a frequency of 4 Hz, the speed was between 1.2-1.6, and it did not run, or it ran very, very slowly. May I ask what caused this

Can you please elaborate on what you mean by " it did not run, or it ran very, very slowly"? I have been running your setup (I had to edit the first line of the keyframe data file to “161, 1” because the original files don’t have the specified number of data points) for 2 hours and reached 3.5 seconds of simulation.
You are right, I have made the changes and it is indeed the issue.
Secondly, at 6hz, if the air velocity is between 0.6-2.2m/s, this problem will also occur, similar to:
MFiX running, simulation time: 0:00:0.832 elapsed time: 4:45:28
MFiX running, simulation time: 0:00:0.832 elapsed time: 4:46:29
MFiX running, simulation time: 0:00:0.832 elapsed time: 4:47:29
MFiX running, simulation time: 0:00:0.832 elapsed time: 4:48:30
MFiX running, simulation time: 0:00:0.832 elapsed time: 4:49:30.
I made the changes like this, changing the values of the solids young’s model and not checking all the particle properties in VTK.
