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 計算流體動力學(xué)的解決方案,特別是針對在無結(jié)構(gòu)性的組合上的多種物理學(xué)問題。
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 在計算全部特征值和特征向量的情況下,算法的計算復(fù)雜性為o(n~2r~2),當(dāng)rn時,優(yōu)于壇一一一~一續(xù)攀遨粼望廷二生掣夔lapack的計算復(fù)雜性o(n’)。
