提示水下爆炸对结构损伤分析中接触面出错，该如何修改？

胡老师：您好！在学习了您的水下爆炸对结构损伤的分析课程后，我对照着您请的内容，做了一遍，在将inp文件放入job中检查时，提示出错，未见设置的两个接触面，如下：

Surface definition assembly_surf-waterjiechu not found.

Surface definition assembly_surf-boxjiechu not found.

The surface assembly_surf-waterjiechu has not been located

The surface assembly_surf-boxjiechu has not been located

Analysis Input File Processor exited with an error.

向您请教是哪个环节出了错，如何修改？谢谢！
