Numerical Analysis of Drug Diffusion in Human Dermal Region with Linear Shape Function

The present model discusses the drug distribution in the layers of human dermal parts. We have considered tissue absorption rate of drug is decreasing function of drug concentration, also considered linear shape functions for approximating element wise approximate solution by Finite Element Method (FEM).In this method each region is referred to as an element and the process of subdividing a domain into a finite number of elements is referred to as discretization. Elements are connected at specific points, called nodes, and the assembly process requires that the solution be continuous along common boundaries of adjacent elements. MATLAB Software used for numerical calculation.
