Where can I find the code for operator+, operator-, operator*, operator/ for, say, a volScalarField for example? Surely, these are called when building the transport equations.
Programmer's Guide v1.5 (9 July 2008) says "Algebraic operations can be performed between Fields subject to obvious restrictions such as the fields having the same number of elements" (P-29) I could re-compile Debug and step through, but can someone spare me the trouble? Thanks |

Thanks for the reply, Niels.
Please let me see if I follow the code correctly by using operator/ as an example 1) Field.C includes "FieldFunctions.C" 2) FieldFunctions.C contains the line BINARY_OPERATOR(Type, Type, scalar, /, divide) 3) BINARY_OPERATOR is defined in FieldFunctionsM.C as #define BINARY_OPERATOR(ReturnType, Type1, Type2, Op, OpFunc) part of which compiles as template<class Type> tmp<Field<Type> > operator / ( const UList<Type>& f1, const UList<scalar>& f2 ) { tmp<Field<Type> > tRes(new Field<Type>(f1.size())); divide(tRes(), f1, f2); return tRes; } 4) If that's the case, then where is divide(tRes(), f1, f2); defined? I see a version is ops.H, but I'm not sure if I follow the syntax there. Thanks |
