ansys 14 workbench中瞬态热分析变温情况无法计算

你看看你的温度 是不是超出了你定义的 材料属性时的温度范围了

1
Temperature-dependent properties have not been specified. The
THOPT,QUASI option does not perform equilibrium iterations. Small
time steps may be required to obtain accurate results.
Use Quasi-Linear Thermal Transient Solution
2
Element shape checking is currently inactive. Issue SHPP,ON or
SHPP,WARN to reactivate, if desired.
3
Material number 18 (used by element 34005 ) should normally have at
least one MP or one TB type command associated with it. Output of
energy by material may not be available.
4
Using 1 iteration per substep may result in unconverged solutions for
nonlinear analysis and the program may not indicate divergence in this
case. Check your results.
5
The closed gap/penetration may be too large. Increase pinball if it is
a true closed gap/penetration. Decrease pinball if it is a false one.
6
Pivot failure in ICCG solver. Matrix is indefinite. If the ICCG
solver fails to reach a converged solution efficiently, you may try
switching to another equation solver.

报错，说一个未知错误，但是恒定温度就可以算啊……

无法计算指的是什么情况？是出错还是其他情况，如果是出错，请给出错误信息，如果是其他情况，请详细描述
