Type

enum mfem::Ordering::Type

Ordering methods:

Enumerator
byNODES	loop first over the nodes (inner loop) then over the vector dimension (outer loop); symbolically it can be represented as: XXX...,YYY...,ZZZ...
byVDIM	loop first over the vector dimension (inner loop) then over the nodes (outer loop); symbolically it can be represented as: XYZ,XYZ,XYZ,...
