Ansys An unexpected error ( SIG$SEGV ) has occurred

进行瞬态分析遇到如下问题：不知什么原因，哪位大神能告诉小弟一下
*** WARNING *** CP = 8.720 TIME= 22:26:30
Some of the defined and selected elements did not require fluid solid
interface. Use the SFELIST,ALL,FSIN command to view a list of
elements that did have fluid solid interface stored.
*** WARNING *** CP = 10.062 TIME= 22:26:30
Some of the defined and selected elements did not require fluid solid
interface. Use the SFELIST,ALL,FSIN command to view a list of
elements that did have fluid solid interface stored.
*** WARNING *** CP = 11.154 TIME= 22:26:31
Element shape checking is currently inactive. Issue SHPP,ON or
SHPP,WARN to reactivate, if desired.
*** WARNING *** CP = 31.465 TIME= 22:27:45
The closed gap/penetration is larger than the pair based pinball.
Please verify the pinball carefully.
*** WARNING *** CP = 31.465 TIME= 22:27:45
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.
*** WARNING *** CP = 18.767 TIME= 22:26:33
Material number 12 (used by element 242891 ) should normally have at
least one MP or one TB type command associated with it. Output of
energy by material may not be available.
*** WARNING *** CP = 3422.818 TIME= 22:51:04
The closed gap may be too large. Increase pinball if it is a true
closed gap. Decrease pinball if it is a false one.
