When I am solving a fluidized bed reactor without reaction. I found this error:

Undefined value found.

- Detail: NaN or Inf found when solving linear system using Vanka.

can someone help me on that?

I think you should change the flow rate of fluid which you are using in simulation as well the viscosity of the fluid and try to get the results.
