This program is a thermal Finite Element Analysis (FEA) solver for transient heat transfer across 2D plates. The program numerically solves the transient conduction problem using the Finite Difference Method. The program displays a color contour plot of the temperature of the plate for each time step.
Results are shown for a square 2D plate with specified boundry conditions.
The model assumes transient 2D conduction with constant properties throughout the simulation. A stable time step must be set by taking into account the physical time constant. Selecting unstable time steps may lead to inconsistent results.
