摘要:Through a fictitious time approach, a nonlinear Poisson-type problem is converted into a time-dependent quasilinear problem. This is further approximated by a sequence of time-dependent linear nonhomogeneous modified Helmholtz boundary value problems, which are solved by the method of particular solutions of Delta-shaped basis functions and approximate fundamental solutions. Numerical results are provided to show the accuracy and validity of the computational method.
