[求助] 求大神帮忙：ANSYS模拟钢筋混凝土板并考虑粘结滑移，无法求解（附命令流）

建模是利用分离式建模并在钢筋混凝土间施加弹簧单元，但在这一块理解不到位很可能出错了。
求解出现的警告和错误主要是说约束不足和出现大位移。

*** WARNING ***                      CP =    54.141 TIME= 17:41:19
There is at least 1 small equation solver pivot term (e.g., at the UZ
degree of freedom of node 1) which may indicate a numerically unstable
model.  Please check your results carefully.

*** WARNING ***                      CP =    61.250 TIME= 17:41:23
An extremely large pivot ratio has been detected by the sparse solver.
This usually indicates a very ill-conditioned matrix or possibly
rigid-body motion.  The solution may be inaccurate or even erroneous.
Please check your results carefully.

*** ERROR ***                         CP =    61.391 TIME= 17:41:23
The value of UZ at node 238 is 1.695793158E+23.  It is greater than the
current limit of 1000000 (which can be reset on the NCNV command).
This generally indicates rigid body motion as a result of an
unconstrained model.  Verify that your model is properly constrained.

*** WARNING *** SUPPRESSED MESSAGE CP =    163.281 TIME= 17:42:23
The unconverged solution (identified as time 1 substep 999999) is
output for analysis debug purposes.  Results should not be used for
any other purpose.
