The default contact stiffness used for contact pair identified by real
The default contact stiffness used for contact pair identified by realconstant set 3 is affected by defined inelastic material properties,
even if the material properties are inactive.You shoud confirm that
the appropriate contact stiffness was used.
这段话的大意是：
实常数 3 对应的接触对收到非弹性材料熟悉的影响，即使该材料熟悉没有激活。你必须确认确实使用相应的接触刚度。
有可能是材料 3 没有定义过。
你具体是做什么问题？
