fatigue 分析时选择材料提示存在free node错误，不能选择材料的region 提示信息如下，跪求给位高手解答啊
$#     Material region default_group contains MPC related free nodes that have no elements associated with them, and no results. It is required that these be removed from the group for a successful fatigue run

谢谢大神帮助，我按照你说的做了可是又产生新问题：疲劳分析失败，给的提示是
$#     The FATTRANS translation was not successful.  No input file was created.  Check the message file for possible problems.
纯菜鸟看不懂啊，跪求大神帮忙分析啊

补充一点存在的free node 是我加的一个MPC,我通过该MPC加的约束和载荷，貌似去掉这部分的话好像是有点问题啊
