Unformatted text preview: problem is axisymmetric only a one-element sector is needed. A small angle Θ = 10° is used for approximating the circular boundary with a straight-sided element. The outer radius ro is arbitrarily selected at a point where the heat source should have negligible effect. Small elements are used adjacent to the heat source where the temperature gradient is the largest. Nodal coupling is used to ensure circumferential symmetry. Triangular and quadrilateral elements are used.
