楼主
各位大神，我有一些问题想请教大家。我现在做的是非线性弹簧（combin39）相关的东西，首先先是引入spring(线性弹簧)，接着调用APDL命令（command命令流），将线性弹簧（combin14）改变成非线性弹簧（combin39）。这些都是在workbench中动态结构中完成的。但是刚计算式就报错了。以下是.err文件中得到的信息：
/COM,ANSYS RELEASE Release 18.0 BUILD 18.0 UP20161219 14:55:59
*** WARNING *** CP = 3.494 TIME= 14:56:01
Element shape checking is currently inactive. Issue SHPP,ON or SHPP,WARN to reactivate, if desired.
*** WARNING *** CP = 5.335 TIME= 14:56:02
Material number 13 (used by element 90732 ) should normally have at least one MP or one TB type command associated with it. Output of energy by material may not be available.
*** ERROR *** CP = 9.610 TIME= 14:56:05
Element 90738 (COMBIN39) with input data also in the compression area must have a data point at the origin.
