计算报错，有如下警告，求解答！

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.

前面几个是warning吧，这个与剖分等设置有关系

最后一个是failure，这个问题我是没有遇到过，不知道可否上传相关的命令流，让大家跑一下，分析下原因？或者你给出更多的background，让大家来分析分析
