warning的實例教程
在我們使用Workbench 仿真時，經常會遇到軟件提示“Errors and Warnings”，大多數人會覺得遇到Warning就可以忽略，所以只要是Warning一概不管，其實這是一種非常不嚴謹的態度，因為在我們的Warning中，有一些Warning不解決的話，會嚴重影響我們的求解進度。
比如今天講解的這個警告，內容如下：One or more MPC contact regions or remote boundary conditions may have conflicts with other applied boundary conditions or other contact or symmetry regions. This may reduce solution accuracy. Tip: You may graphically display FE Connections from the Solution Information Object for non-cyclic analysis. Refer to Troubleshooting in the Help System for more details.
上面警告的大致意思就是模型中有存在過約束的幾何，導致邊界條件沖突，出現Warning,那么如何解決呢？要修復Warning，只要在某一邊界條件下去除該幾何即可！具體案例如下

展開 個人認為如果使用beam161一定會出現兩個警告，一個是哪些節點是無質量節點，另一個是無質量節點的個數，我的兩個Warning附在最后，對照節點號進入模型查看，發現這些節點都是beam單元的方向節點（原文是beam element orientation）。
查了相關資料了解到，這個警告的初衷是防止自底向上建模時出現有不屬于單元的獨立節點問題，我遇到的顯然不是這個問題，搞清楚了問題的緣由就可以放心的忽略不計了。
我們總希望計算完成彈出一個Solution is done，但如果有警告就不會這樣，我們也不用著急，只要分析清楚警告的原因，理解它。就可以該改的改，該忽略的忽略了。

*** Warning:
The left side rotation is equal to zero.
Therefore, the front view swing arm length will equal zero.
acar/asfvsl
*** Warning:
The right side rotation is equal to zero.
Therefore, the front view swing arm length will equal zero.
acar/assvsa
*** Warning:
The left vertical deflection compliance terms are equal to zero.
Therefore, the side view swing arm angle will equal zero.
acar/assvsa
*** Warning:
The right vertical deflection compliance terms are equal to zero.
Therefore, the side view swing arm angle will equal zero.
acar/svsl
*** Warning:
the left side rotation is equal to zero.
therefore, the side view swing arm length will equal zero.

(3) 點擊【Submit】，提交作業，查看作業監控窗口，確保無錯誤（Error）或警告（Warning）提示，等待計算完成。
四、結果后處理（Visualization）
4.1 查看變形與應力分布
(1) 計算完成后，點擊【Results】進入可視化模塊，默認顯示最后一步的結果。
設置網格劃分方式
圖19 將網格劃分方式設為Advancing front
12）劃分網格
圖20 分割應力集中區域后，使用Advancing front算法生成的網格
13）檢驗網格質量
圖21 網格檢驗結果
如圖21所示，在模型中沒有單元顯示為黃色或紅色，且窗口底部信息區中顯示數據為0 Analysis errors和0 Analysis warnings

WARNING: No cached password or password provided.
Such SPCs will be skipped in an implicit simulation and a warning issued.</p><p><strong>我們強烈建議您不要將節點約束（例如，通過 *BOUNDARY_SPC_OPTION）應用于剛體的節點，因為在顯式模擬的情況下，這樣做可能會損害預期的約束。在隱式模擬中將跳過此類 SPC 并發出警告。
