Convergence problem fludized bed
4 Attachment(s)
Hello. I'm trying to simulate a 3D fludized bed using a eulerian-eulerian approach. When I restrict the inlet area, fluent diverges and show me the message: floating point exception. I'm using gidaspow for granular viscosity and drag coefficient.
inlet velocity: 0.12 m/s diameter of particles: 0.000163m density: 2820 kg/m3 base radius: 0.073m inlet radius: 0.01m step size: 0.001 element size: 0.005 If my inlet area is the base area (0.073m of radius) the is no problem, but when I put the named section with 0.01m of radius, the problem diverge after 20 interections. Thank you very much in advance |

A general advice, in the tui you can type /report/mphase-summary and select 1 for verbosity. It will give you all sorts of recommendation and suumary |
