Consider a quadratic heat-conduction line element with three equally spaced nodes as shown in Figure 12.26:

Posted: January 9th, 2022

(a) Using the quadratic element, determine the heat conduction matrix.

(b) Using one linear element for the left portion, and one quadratic element for the right portion of the wire shown in Figure 12.25, determine the heat flux at point A and both ends of the wire.

(c) Comment on the results by comparing with the results of Question 3.
