Why does ANSYS 10.0 evaluate the polynomial defined below at +/-9999 degrees
and not the two temperatures I specified? ANSYS 7.1 evaluated this polynomial at
0 and 875 degrees as I intended.
In ANSYS 10.0, if you only use two temperatures with the polynomial option
for temp-dependent material property input, the polynomial is evaluated at +/-9999
as would be done for a linear property no matter what temperatures you specify with
MPTEMP. This probably gives a user incorrect results since straight line interpolation
is used between the two evaluated temperatures. The input of a number of temperatures
equal to the order of the polynomial (in the above example 2) will be blocked in ANSYS 11.0.
[Ref: Defect 38335] A workaround is to specify 3 or more temperatures.
