Hello, I am modifying scalartransportFoam to make some multiple scalar properties I need. I first modified to create scalar named 'zeta', by modifying PDE from scalarTransport.c and changing name of scalar from 's' to 'zeta'. Then, i made another code which is also modified version of scalarTransport.c, which uses 'zeta' scalar for transport equation.


So, I tried to make the code gets data of 'zeta' as it does to rho and phi, so I wrote the line 'zetaName_ = dict.lookupOrDefault<word>("zeta", "zeta");' and 'mesh_.lookupObject<volScalarField>(zetaName_);' each below the part they reference rho and phi. However it seems like the code doesn't compile well.



Below is the error code

avgageTransport.C: In member function ‘virtual bool Foam::functionObjects::avgageTransport::read(const Foam::dictionary&)’:
avgageTransport.C:212:5: error: ‘zetaName_’ was not declared in this scope

What may have caused the problem? Do these lookupOrDefault and lookupObject functions work different to rho/phi and zeta? I am not sure about how OF saves and load variable data
