[問題] ANSYS分析上的問題

[linefong (下一站天王)]

想請教一下~
我在分析ANSYS的時候
出現了以下的錯誤訊息
但是我不太懂他的意思

 *** ERROR ***                           CP=     62.531   TIME= 13:36:27
 The value of UY at node 8694 is 3.733233267E+10.  It is greater than
 the current limit of 1000000.  This generally indicates rigid body
 motion as a result of an unconstrained model.  Verify that your model
 is properly constrained.

 *** ERROR ***                           CP=     63.062   TIME= 13:37:03
 *** MESSAGE CONTINUATION ---- DIAGNOSTIC INFORMATION ***
 If one or more parts of the model are held together only by contact
 verify that the contact surfaces are closed.  You can use the CNCHECK
 command to check the initial contact status in the SOLUTION module.

希望有高手可以幫幫我唷
謝謝~~

→ ac0118:應該是你的接觸面設錯了…兩者可能沒有接觸…
→ ac0118:去help看看CNCHECK這個指令吧…應該有解決方法…
→ ac0118:ANSYS的HELP做的不錯…在發生問題時很有幫助的…
推 skygogo:大大好厲害阿..但是我想請問一下唷..
→ skygogo:CONTACT　有一定要接觸嗎..還是可以有GAP? 謝謝
推 ac0118:那要看你是做什麼分析…像掉落試驗就有gap
→ ac0118:理論上應該是要你的問題而定…
