operating on a specific cellZone ???
Hi.
I have been able to create cellZones in my mesh, which as best as I can tell are simply sets of cell indices. My question is about how-to: How do I make use of cell zones?? For example, I want to give a value to a field only in a certain cellZone. I imagine this operation to be akin to defining boundary conditions on only specific patches, but so far I have been unable to find any example code for cellZones. I found something relevant looking in a file called mixerFvMesh.C, shown below: const labelList& cellAddr = cellZones()[cellZones().findZoneID("carboxen")]; forAll (cellAddr, cellI) { k_ads[cellI] = k0_ads*Foam::exp(-E_ads/(R_gas*T[cellI])) ; // rate of adsoption of HCHO onto carboxen [1/s] } Are there some .H files or other preparations I would need to get this code to compile?? A compile library?? my error output is: cEqn.H: In function âint main(int, char**)â: cEqn.H:5: error: no matching function for call to Foam::cellZone::cellZone()â any help greatly appreciated. |
An in-house colleague kindly sorted this out for me.
The syntax is: const label cellZoneID = mesh.cellZones().findZoneID("carboxen"); const labelList& cellAddr = mesh.cellZones()[cellZoneID]; etc etc... |
