"Witryna16 cze 2024 · It is easy to solve this equation by integration and we see that u = Ax + B for some constants A and B. Suppose we have an insulated wire, and we apply constant temperature T1 at one end (say where x = 0) and T2 on the other end (at x = L where L is the length of the wire). Then our steady state solution is u(x) = T2 − T1 L x + T1. " - In 1d steady state problems at x x0 t t0 is a
