In this paper, the finite point method (FPM) is presented for solving nonlinear reaction-diffusion systems which are often employed in mathematical modeling in developmental biology. In order to avoid directly solving a coupled nonlinear system, a predicator-corrector scheme is applied. The finite point method is a truly meshfree technique based on the combination of the moving least squares approximation on a cloud of points with the point collocation method to discretize the governing equations. The lack of dependence on a mesh or integration procedure is an important feature, which makes the FPM simple, efficient and applicable to solve nonlinear problems in complex domains. We present numerical solutions for two cases of interest, namely the well-studied Schnakenberg model and the Gierer-Meinhardt model, in various regions to demonstrate the effects of various domain geometries on the resulting biological patterns.
