Dear Developers
Sorry to bother you for some basic questions. although they might seem quite trivial to the experienced OpenFOAMers :-) but I request you to explain them. 1) List<type> is a 1D construct and when instantiated for <type> leads to a List of scalar, vector, tensor etc. The Field<type> is inherited from List<type> and is a 1D construct as well. Please explain how does the two differ conceptually. Both List<type> and Field<type> have some constructors in common, for example: for List<type> // Constructors //- Null constructor. inline List(); //- Construct with given size. explicit List(const label); //- Construct with given size and value for all elements. List(const label, const T&); For Field<type> Field(); //- Construct given size // Used for temporary fields which are initialised after construction explicit Field(const label); //- Construct given size and initial value Field(const label, const Type&); further for class Field<type> constructors then we have various option using mapping between two fields. 2) Further DimensionedField<> builds upon Field<> and dimensionSet but I did not understand how does GeoMesh works. is DimensionedField<> a 1D construct as well. Does it already contains the mesh information and data for the Field<type> associated with it. And with respect to mesh info, does it contains boundaryMesh info as well. 3) Further GeometricField is build upon DimensionField and contains GeometricBoundaryField. Is GeometricField still a 1D construct?. With respect to GeometricBoundaryField I am unable to understand FieldField<patchfield,>. What does PatchField corresponds to ?. Please throw some light on this.I thank you in advance. With Best Regards Jaswinder |
