Hi guys,
I have a problem probably you know how to fix!

Starting from the tutorial of fluidized bed in twoPhaseEulerFoam, I changed turbulentProperties.particles file in kineticTheory to switch on the KTGF, I set U.air at (0 0 0) and the particle diameter to 2.5e-3. Nevertheless in paraFoam I get a small fluidization, whereas with phasePressure model I don't.

How is it physically possible?

Probably I should change some parameters in the KTGF setting, I tried, but nothing!!

Could you help me, please?
