umat相关

fabcdefg

刚学abaqus，想试一下简单的umat例子，abaqus版本是6.14，vs2013，ivf2013，关联之后全部都是pass，但是提交之后显示10 elements have been defined with zero hour glass stiffness. You may use *hourglass stiffness or change the element type. The elements have been identified in element set ErrElemZeroHourGlassStiffness.

job.log显示的是
C:\Users\singlim\AppData\Local\Temp\singlim_Job-1_7388\Source1.for(1): (col. 18) remark: umat has been targeted for automatic cpu dispatch
End Compiling Abaqus/Standard User Subroutines
Begin Linking Abaqus/Standard User Subroutines
   正在创建库 standardU.lib 和对象 standardU.exp
End Linking Abaqus/Standard User Subroutines
求教各位大神这是哪里出问题了

是不是用的减缩积分单元？element type中hourglass control可选择enhanced，或者选择stiffness 定义沙漏刚度。

谢谢层主，选择了enhanced之后已经解决了
