Detailed Description

template<typename MemorySpace = Kokkos::DefaultExecutionSpace::memory_space>
struct chemistry::SparseLUPattern< MemorySpace >

The pattern of a reactor Jacobian in (Y_1 .. Y_Ns, T) without its rank-one part, an elimination order, the fill of its LU factors and the operations of a factorization without pivoting, on the device.

The Jacobian splits as J = J_s + u v^T: v_j = 1 / W_j for the species (0 for T), and u_k = W_k sum_i nu_ki dq_i/d[M] (eff_i,default) + ... the part of d omega_k / d C_j that is the same for every species j (third-body concentrations with their default efficiency, and the pressure of PLOG and Chebyshev reactions). J_s keeps the mass-action terms, the extra efficiencies and the T row and column. The species are ordered by minimum degree, T last; the static pattern of L + U of I / (gamma h) - J_s is factored without pivoting (a vanishing pivot rejects the sub-step).
