NAFEMS Benchmark: One-dimensional heat transfer with radiation

Problem Description

Figure 1 shows a one-dimensional bar. The temperature is maintained at 1000 K at one end (point A). The other end at point B is exposed to radiation to an ambient temperature of 300 K. 10 elements in the length direction are used to model the bar. The temperature at the point B is obtained solid elements and compared with the reference solution given in NAFEMS.
