3-D Thermal Solid Elements (SOLID70) Input Listing: vm118.dat Test Case
Determine the centerline temperature and the surface temperature Ts of a bare steel wire generating heat at the rate q . The surface convection coefficient between the wire and the air (at temperature Ta) is h. Also determine the heat dissipation rate q.

The problem is solved first using conducting area elements (PLANE55) and then using conducting solid elements
(SOLID70). Since the problem is axisymmetric, only a one-element sector is needed. A small angle Θ = 10° is used
for approximating the circular boundary w...
