Better attach your .inp file, the file for the umat subroutine, and the command you used. This way, other people might test it for you.

   我在运行这个例子时，也出现了问题，
在datacheck时出错：提示：

在msg文件中提示为：

  ***ERROR: USER SUBROUTINE UMAT IS MISSING
这会是什么原因，是那儿出了问题咧。

The problem must be here -->
   "***ERROR: USER SUBROUTINE UMAT IS MISSING"

不好意思，是我自己的原因。已经解决。将user忘记了。另外，好像user文件名的扩展必须是.for文件。.f文件还会提示出错。
