[求助] 求助：ANSYS求解板四面受弯的问题，代码已求解但是有错误信息，希望大神帮看一下

错误信息是：
*** WARNING ***                      CP = 1083.474 TIME= 21:13:08
Material number 12 (used by element 8657 ) should normally have at
least one MP or one TB type command associated with it.  Output of
energy by material may not be available.

*** WARNING ***                      CP = 1083.942 TIME= 21:13:09
Some MPC/Lagrange based elements (e.g.8658) in real constant set 12
overlap with other MPC/Lagrange based elements (e.g.9165) in real
constant set 16 which can cause overconstraint.

*** WARNING ***                      CP = 1083.942 TIME= 21:13:09
Overconstraint may occur for Lagrange multiplier or MPC based contact
algorithm.

我的模型是一个五层的层压板，荷载是四周受弯矩。
