해석시 다음과 같은 메세지가 뜸니다

[전은옥]

해석을 하면 다음과 같은 경고메세지가 뜸니다.
There are 5 small equation solver pivot terms.

또한
DOF(e.g. displacement)limitexceeded at time 10
(load step 1 substep 1 equilibrium iteration 1)
Max. absolute value = 5.69751138(limit = 1)
at UZ of node 129
May be due to an unrestrained or unstable model
과 같은 에러메세지가 뜸니다.
무엇이 문제인지 모델링이 잘못된것인지 도움 부탁드립니다.
