Authors: Kiran S, Dhananjayamurthy B V, Shivaram K T


This paper presents, numerical solution of partial differential equations over a triangle domain, which   are approximated by generalized Gaussian quadrature rule, discretize the triangle domain into three linear convex quadrilateral elements and jocobian is same expression for three quadrilaterals elements by transformation of global coordinates into local coordinate system, the performances of the method is illustrated with numerical examples
