How can I export a variable pr
How can I export a variable profile on a boundary patch ?
More precisely, how can I expo
More precisely, how can I export the content of a fvPatchField (either <double> or vector<double>) to a file ?
To better understand how class
To better understand how classes work, I tried to play a little. What I do not understand is why this code :
Info << "c(1) = " << c << endl;
gives the result c(1) = 5
since in the member functions of List I can not find the operator +

Not sure what else you have expected: 2 + 3 = 5.
Here, you created 2 lists of size 10, then assigned all elements of first list to 2 and all elements of the second list to 3 and summed them up.
The actual operator+(...) you are using is:
operator Op(const UList<type1>& f1, const UList<type2>& f2);
Beware of the macros...
Why are some operators impleme
Why are some operators implemented via member functions and others via macros ? It seems to me that macros are harder to find in the documentation ?
Because of code re-use and con
Because of code re-use and consistency. Templates, (of course, you mean templates! rather than member functions) are preferred whenever possible - in fact you will see that the macro I've showed you actually defines a template.
Other possible question you may be asking is why is eg. operator+= a member and operator+ a friend. There are VERY good reasons for it, to do with automatic type conversion on the rhs argument. A good C++ book will tell you why.
