Hi.


I have a simulation adapted from simpleFoam for a chemical separation process. It was working fine in an old OpenFoam version, but our server has to be updated, and we are trying to get it to run with v2212.


Many problems have already been corrected, mainly involving adding more specific header files, as well as adding more items to the options file that the system seems to specifically seek.


We are now stuck with the following error, where the compiler won't accept an assignment statement for an inlet velocity on a surface patch. This kind of line was fine for decades, not sure why it's suddenly a problem.


>>>

Does anyone know how to get a v2212 compiler to accept this line? Do we need header files in v2212 related to fvPatchField? Normally, this was all part of standard OpenFoam internals that a simpler user didn't have to be concerned about.


thanks !

figured it out !!



there were two header files required that were in createFields.H rather than in the .C file in my example, so they went unnoticed.


added:
#include "createMRF.H"
#include "createFvOptions.H"

to my createFields.H file, and the code compiles !!




thanks.

actually, I was wrong, the problem persists, openfoam v2122 will not allow:


U.boundaryField()[patchIn][0].component(0) = Umax*(1.0 - r2);


it seems to report something like a casting error.

Strange, since this kind of assignment always worked in the past.


Any ideas on how to make that assignement I'm seeking??


thanks.
