Since the linear system of rotation operator is degenerate, the matrix is ill-condition. For the pre-condition of conjugate gradient method, the Balancing Domain Decomposition method is employed. Since the subspace of the kernel of rotation, i.e. balancing space, is known as the scalar potential velocity field, we solve the discretized Poisson-like equation with the Shur complement to eliminate the degenerate components., 資料番号: AA0063742014, レポート番号: JAXA-SP-07-016}, pages = {81--86}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {構造メッシュ差分法における任意渦度の流れ場の生成}, volume = {JAXA-SP-07-016}, year = {2008} }
