The SpaceDim C++ integer constant specifies the dimension of the Chombo library to be built. It is initialized to the value of the macro CH_SPACEDIM. Hence it will have one of the values 1, 2, or 3.
C++ code that depends on the dimensionality of the problem that you're trying to solve should be cast in terms of this constant, instead of the CH_SPACEDIM macro, if possible, as constants are visible to debuggers while macros are not.
