A particular solution Trefftz method for nonlinear Poisson problems in heat and mass transfer
The authors present a collocation method for the nonlinear Poisson equation, based on radially-symmetric particular solutions which have singularities outside the domain of the problem. The nonlinear source term is handled by inverting the collocation matrix for the interior points and using quasi-Newton iterations.
