Hi,

I have modified the pUCoupledSolver to account for transient flows and I have integrated the pressure force from channelFoam to use the solver for simulation of turbulent channel flows.

But if I use the AMG solver for Up I'm getting this error message:

--> FOAM FATAL ERROR: 
Unknown BlockGAMGInterfaceField type cyclic.
Valid BlockGAMGInterfaceField types are :
1
(

)


    From function BlockGAMGInterfaceField::New(const GAMGInterface& GAMGCp, const BlockLduInterfaceField<Type>& fineInterface)
    in file lnInclude/BlockGAMGInterfaceField.C at line 50.

FOAM exiting

The BiCGStab solver is working fine but very slow compared to the original segregated approach when using channelFoam.


Best regards

Matthias

I have added a cyclicBlockGAMGInterfaceField now and doing some simulations if it works.


First tests show that the BiCGStab solver performes better than the AMG solver using the block coupled approach simulating a channel flow.
