Thermal Elements Jake Blanchard Spring 2008
Thermal Elements These elements calculate temperatures in solids There are 1-D, 2-D, and 3-D elements All have just 1 DOF per node Properties are thermal conductivity (k) for steady state analysis and density ( ) and heat capacity (cp) for transient analyses Boundary conditions can be temperatures, heat fluxes, or radiation Volumetric heating is also possible
