computational fluid dynamics ( cfd ) solver aimed to solve multi-physics problems on unstructured grids ( inviscid euler, navier-stokes flows, heat transfer ) . f90 based . mpi, cgns, metis, lapack libraries used 计算流体动力学的解决方案,特别是针对在无结构性的组合上的多种物理学问题。
an eigenvalue interlacing theorem is given and proved . each eigenpair is computed by bisection and generalized rayleigh quotient iteration . for computing all eigenvalues and eigenvectors is o ( n2r2 ), it is less than o ( n3 ), which is the computational complexity of lapack, when r n 在计算全部特征值和特征向量的情况下,算法的计算复杂性为o(n~2r~2),当rn时,优于坛一一一~一续攀遨粼望廷二生掣夔lapack的计算复杂性o(n’)。
