Divergence or no convergence in porous environements
 
Hello everyone !

I got a pbm with a porous environment :

I'm searching the permeability of a porous environment that i created with Fluent but when i applicated these parameters :

- Viscosity model : Laminar
- Fluid material : water liquid

-> there is no convergence after many iterations

- Viscosity model : k-epsilon/omega

-> divergence in AMG solver : epsilon/omega

I don't know if i have to change the nut or something else, please help me !

Thanks

Max

The problem is with your inputs, not the porous media

What did you mean with "imputs", what parameter should i change ? The solution controls ?

I just re-made my mesh, and it has converged !!

Thank you

Max
