1-D Oscillating Transient Thermal Analysis

A rectangular plate (0.1 m x 0.01 m) is subjected to a one-dimensional sinusoidal variation of temperature at its right-hand end, constant temperature at its left-hand end, and a uniform initial temperature. Determine its temperature at x = 0.09 m.

In the figure, ω/2π = 0.0125 Hz, θ = 0, a = 1000.

The Y dimension of the model is selected arbitrarily because the problem is one dimensional.
