Abstract
A finite element method involving collocation method with sextic B-splines as basis functions has been developed to solve seventh order boundary value problems. The seventh and six order derivatives for the dependent variable is approximated by the central differences. The basis functions are redefined into a new set of basis functions which in number match with the number of collocated points selected in the space variable domain. The proposed method is tested on three linear and two non-linear boundary value problems. The solution to a nonlinear problem has been obtained as the limit of a sequence of solutions of linear problems generated by the quasilinearization technique. Numerical results obtained by the present method are in good agreement with the exact solutions available in the literature
