Question: Consider the two-dimensional geometry below; default thickness is 1.0 m. Boundary conditions are: 1. T = 100 C along edge AB 2. Zero heat

Consider the two-dimensional geometry below; default thickness is 1.0 m. Boundary conditions are: 1. T = 100 C along edge AB 2. Zero heat flux along edge DA 3. Convection along edges BC and CD with 0 C ambient temperature and a surface convective coefficient of 750 W/m/degree C. The material conductivity is 52 W/m/degree C. Find the smallest bilinear mesh and biquadratic mesh necessary obtain the reference value temperature at point E of 18.3 C, within a tolerance of 3 percent. This is a test recommended by the NAFEMS, the National Agency for Finite Element Methods and Standards. Note: Provide detailed comments on your solution approach and interpretation of results. Note that the SMALLEST mesh is being asked, i.e. lowest number of finite elements/nodes.
