Interested readers +can obtain fundamental informations about full-core calculations in Chapter~5 +of Ref.~\citen{PIP2009}. The multigroup +and multidimensional form of the diffusion equation or simplified $P_n$ equation +is first discretized to +produce a consistent matrix system. This matrix system is subsequently solved +using iterative techniques (inverse or preconditioned power method with +ADI preconditioning) and sparse matrix algebra techniques +(triangular factorization). The actual implementation of TRIVAC allows the +discretization of 1-D geometries (slab and cylindrical), 2-D geometries +(Cartesian, cylindrical and hexagonal) and 3-D geometries (Cartesian and +hexagonal). Many discretization techniques are available, including mesh corner +or mesh centered finite difference methods, collocation techniques of various +order and finite element methods based on a primal or dual functional +formulation. TRIVAC also permits the equations of the generalized +perturbation theory (GPT) to be solved as fixed source eigenvalue problems. +Finally, several implicit numerical schemes are available for the solving of space-time +neutron kinetics problems. + +\vskip 0.15cm + +The execution of TRIVAC is controlled by CLE-2000.\cite{cle2000} It is +modular and can be interfaced easily with other production codes. -- cgit v1.2.3
