Question:
A finite element mesh consisting of a linear triangular element (element 1), a linear quadrilateral element (element 2) and 5 nodes is shown in the figure below. Unit of the nodal coordinate is meter. Temperature boundary condition T = 20°C is applied to the left and bottom edges. Heat flux boundary condition q̅ = 10y W/m is applied to the right edge. Heat flux boundary condition q̅ = 5 W/m is applied to the top edge. Isotropic thermal conductivity of material in the triangular element 1 is k1 = 5 W /°C. Isotropic thermal conductivity of material in the quadrilateral element 2 is k2 10 W/°C. Heat source through the whole domain is uniform and constant s = 2 W/m2. Please calculate the conductance matrix
