Hi Foamers,
As in fluent we can fix the values of a field variable in a fluid/solid zone as in like setting up a BC for the cell values for that particular zone. As in fluent, the transport eqn for the particular variable in that zone is not solved. Is there a way in OF to model this. Thanks Sumeet |

As in like MRF and porous zones we add source terms to Ueqn and then adjust the boundary conditions.
Can we do it in similar fashion -- Call the fixed zone in solver like fixedzonesimpleFoam while solving lets say U equation (fixing the values of U variable) Fixedzone. - don't solve for that variable (UEqn) Adjust zone - interpolate the internal zone using fixed values as input Adjust BC's, fix the value in the patches (interfaces between zones) I did a search but couldn't find anything related Any suggestions. ?? |

Hi Foamers,
I have managed to define a new fixed value zone on the terms of porous/MRF Zones. However I need to compile this zone so that OF understands this new zone. Compilation methods for applications (solvers), BC's, trubulence models, etc are available. Is there any guidelines available to compile a new zone. I'll try for myself, any suggestions are welcome. Thanks, Sumeet K. |

Hi,
I also want to handle a porousZone as a zone with a fixed value for k, becaus I want to define it with k=0 as a laminar zone. So can you help me how I schould do it. Best Regards Chrisi |
