各位前辈好
小弟最近使用ANSYS Workbench在做Solid - Shell的接触分析
出现以下错误 使用Conta173 /Targe170
结构则为Solid 187/186 及 Shell 181
请前辈们帮忙看看@@
MPC approach only supports certain bonded/no-separation contact
options. For general contact switch to other contact algorithm.
Contact detection at: nodal point (surface projection based)
Average contact surface length 2.2923
Average contact pair depth 2.1571
User defined pinball region PINB 4.8721
也有些警告想问问前辈怎么修改
警告一
Material number 27 (used by element 3261118 ) should normally have at
least one MP or one TB type command associated with it. Output of
energy by material may not be available.
警告二
Overconstraint may occur for Lagrange multiplier or MPC based contact
algorithm.
The reasons for possible overconstraint are:
*Boundary conditions, coupling, and/or constraint equations have been
applied on certain contact nodes (for example 5997983).
不过我在设定中已经将接触公式改成MPC
也尝试改接触元素的KEYOPT 将其改成Bonded 及MPC
但仍然跑出ERROR
想请问前辈们是否有遇到这样的问题
想寻求能更改的方向
谢谢!
