Porous media
Hi,
I am trying to introduce a porous media zone in my problem of natural circulation. I know the pressure drop in this zone. But when I am trying to introduce the porous media zone, I have this error message: Error: Internal error at line 562 in file 'amgif.c'. divergence detected in AMG solver Error Object: () Could anyone help me? Maybe anyone knows what FLUENT tutorial treats this problem. Thank you |
Re: Porous media
Your problem isn't stable - some of the variables change rapidly and the solution doesn't converge. May be You will have success by reducing the relaxation factors.

Re: Porous media
Please note that you cannot use the PISO scheme with porous medium.

Re: Porous media
Thank you very much,
I have use another discretization scheme, and it works. Thank you once more |
Re: Porous media
You also have to take in account that if the drop pressure is big - you should run Fluent in double precision
f.e.: fluent -2ddp |
