SUMMARY

The discussion centers on solving the 1-D heat equation for an aluminum cylindrical rod that is 1.0 meter long, connecting two heat reservoirs at a constant temperature of 300 K. The initial condition specifies that the center of the rod is heated to 600 K, while the ends remain at 300 K. The key focus is on determining the appropriate boundary conditions for this system, which are essential for accurately modeling heat transfer in this scenario.

Consider an aluminum cylindrical rod 1.0 meter long connecting two heat reservoirs.
Both of the reservoirs are maintained at T=300 K. Initially, the cylinder is at 300 K,
except for the center point of the cylinder which has been rapidly irradiated to a
temperature of 600 K. There is no heat loss from the rod. Consider the system to be one-dimensional.

How do i find the boundary conditions?
