  We present a hybrid mimetic spectral element formulation for Darcy flow. The
discrete representations for 1) conservation of mass, and 2) inter-element
continuity, are topological relations that lead to sparse matrix systems. These
constraints are independent of the element size and shape, and thus invariant
under mesh transformations. The resultant algebraic system is extremely sparse
even for high degree polynomial basis. Furthermore, the system can be
efficiently assembled and solved for each element separately.
