Step 3: Finally, the heat energy for the given inputs will be displayed in the output field.trarily, the Heat Equation (2) applies throughout the rod. 1.2 Initial condition and boundary conditions To make use of the Heat Equation, we need more information: 1. Initial Condition (IC): in this case, the initial temperature distribution in the rod u(x,0). 2. Boundary Conditions (BC): in this case, the temperature of the rod is affected loon salts juice
