TFM simulation of a spouted bed always diverges

Hello,
I am trying to simulate a rather simple case of a 3D spouted bed with a solid inlet. I have already tried many combinations of settings and mesh properties, but the simulation always diverges after a few simulated hundredths of seconds. Any suggestion will be very appreciated.
Thanks,
Filippo
