import手册例题inp却显示无法读入模型（User-defined elements and/or super elements

我做的是Abaqus Example Problems Manual
  2.1.15 Seismic analysis of a concrete gravity dam
读入第一个inp文件koyna_freq.inp运行正常
读入第二个inp文件koyna_std.inp， abaqus显示错误如下：
The model "koyna_std" has been created.
AbaqusException: An input file containing User-defined elements and/or super elements cannot be imported by the input file reader.  This occurred while creating deformable part PART-1. The part will not be created.
WARNING: Part instance PART-1-1 references an empty part. A new part named PART-1-1 will be created from the mesh data in part instance PART-1-1.
WARNING: Empty part instance PART-1-1. This occurred while processing part PART-1. Neither the original part nor the part instance PART-1-1 contain mesh data.

我仔细检查了inp文件，确实没有多余空行空格。相关的inp文件也都存在默认目录下。
清高手指教，这个模型怎么读入才可以正常运算？（已上传inp文件）

回复 1# ayy8999
我刚才把koyna-std中的以下内容删去，
*USER ELEMENT, NODES=2, TYPE=U1, PROP=3, COORD=2
1, 2
*ELEMENT, TYPE=U1
10001, 1, 101
*ELGEN, ELSET=ADDED_MASS
10001, 36, 100, 1
*UEL PROPERTY, ELSET=ADDED_MASS
91.75, 91.75, 1000.0

就可以生成模型
请问user element 和 uel property指的是什么？在手册的哪些章节有介绍？我用手册搜索功能没搜到有用信息，还望高手指教！
