Title of program: ILUBCG2 Catalogue Id: AALX_v1_0 Nature of problem Certain elliptic and parabolic partial differential equations that arise in plasma physics and other applications are solved in two dimensions. The implicit solution techniques used for these equations give rise to a system of linear equations whose matrix operator is sparse - often 9-banded - and generally asymmetric. We provide a fast algorithm for their solution. ADAPTATION SUMMARY: Vol:Year:Page 55:1989:359 "0001ILUBCG2-11" "ILUBCG2-11: solution of 11-banded nonsymmetric linear equati ...
