*HEADING
EXPLICIT RIGID BODY ISOTHERMAL / TEST CFILM AND CFLUX [C3D10MT ]
**
** The temperature varies only in time and the fluxes are zero
** The time increment is specified using Direct User Control
** See ch. 1.11.6 of ABAQUS/Verification Manual
**
** The temperature at all of the nodes decreases exponentially from
** 100 to 20 in the first step, and then increases linearly back
** to 100 in the second step.
