.... involving either A or B has to be performed, the control is returned to the user (and such a computation can be specialized for particular applications) b) ARNCHEB is an implementation of the Arnoldi Tchebycheff algorithm for the solution of eigenproblems involving non Hermitian matrices [2,3,4]. The package can be applied to problems Ax = Bx where A is real and B = I (a collaboration between CERFACS and Aerospatiale) A complex and B = I, and A complex and B Hermitian positive definite or complex. CG and GMRES type iterative methods or the LU factorization may be used for finding ....

....fields, such as fluid dynamics. However, we show here a problem proposed by the Structural Research and Development Department at Aerospatiale, in Toulouse. It corresponds to the modelling of a flutter phenomenon, with a coupling of a torsional vibration and a bending motion of a wing in flight [2,3,4,5]. In such a case, the equation of motion (5) is corrected to M u Ku = F u (7) where F is nonsymmetric and nonnormal, corresponding to an estimation of the aerodynamic contribution of the discretization points. Then, equation (7) HCM Advanced Finite Elements 7 can be solved through the ....
