Issue with gravity force in Particle Tracing Module

Hello everyone,
I'm trying to simulate a fairly simple process. I have a reactor tube with a ceramic boat containing some particles. I want to know at which initial flow rate the particles will start to move towards the output. However, when adding the gravity force in the Particle Tracing Module, the particle simply vanish in the second time step.
I've tried changing the mesh size, decreasing the time step, change the wall interaction (freeze, bounce, stick). Removing the gravity makes the particles not disasppear, but don't make sense either. Did anyone have the same issue.
In a simulation with really small time steps, the particles seemed to pass through the input wall. I don't know if that is an error in COMSOL or I didn't make the correct inputs.
Best regards,
Artur
