hypermesh错误2203怎么改？

如题，貌似是网格的错误。
查看out文件是这样的：
ITERATION 0
Element No. 163 Element Type = TRIA3
WARNING - Outside of recommended range: Vertex Angle = 11.591
lower limit = 15.000
Element No. 164 Element Type = TRIA3
WARNING - Outside of recommended range: Vertex Angle = 11.591
lower limit = 15.000
Element No. 165 Element Type = TRIA3
WARNING - Outside of recommended range: Vertex Angle = 11.591
lower limit = 15.000
NOTE : other similar error/warning messages were suppressed,
use PARAM,CHECKEL,FULL to obtain full report

Element Quality Check Summary

我用element check 检查了以后还是不行啊。。
请问下各位前辈应该怎么改啊？
老是计算出错
谢谢
