Part II of this paper demonstrates how the method has been used to provide a very accurate fit to a corneal measured data set. All calculations and generation of graphics were performed using the R language programming environment, and RStudio, the integrated development environment (IDE) for R, both of which are open source and free to download. Pepper, Department of Mechanical Engineering, University of Nevada, Las Vegas, 4505 Maryland Parkway, Las Vegas, NV 89154-4027. The results show good agreement with published corneal data and allow back calculations for estimating certain physical properties of the cornea, such as tension, and elasticity coefficient. The meshless method yields close approximations to results obtained with mesh-dependent finite-difference, finite-volume, and finite-element techniques. It also provides an alternative to corneal topography modeling methods requiring accurate material parameter values, such as Young's modulus and Poisson ratio, that may not be available. Stationary approximation:Scale the shape parameter 'according to thell distance(or meshsize) h so that we end up using. meshless and are based on collocation in a set of scattered nodes. This new approach does not rely on radial symmetry or other simplifying assumptions in respect of the cornea shape. In this paper the RBF approximation methods are briefly described, a new approach to. A full two-dimensional nonlinear thin membrane partial differential equation (PDE) model is introduced and solved using the multiquadratic (MQ) and inverse multiquadratic (IMQ) RBFs. Whereas other works focus almost entirely on theoretical aspects or applications in the engineering field, this book provides. We discuss the solution of cornea curvature using a meshless method based on radial basis functions (RBFs). Meshfree approximation methods are a relatively new area of research, and there are only a few books covering it at present.
