| ANSYS Structural的接觸分析功能，包括了變形體對變形體(deformable-to-deformable)接觸，和剛體對變形體(rigid-to-deformable)接觸，而接觸元素(contact elements)的類型有點對點(node-to-node)、點對面(node-to-surface)、面對面(surface-to-surface)元素。ANSYS Structural除了可處理一般實體元素的接觸分析之外，亦可處理殼元素對實體元素(shell-to-solid)、殼元素對殼元素(shell-to-shell)、樑元素對殼元素(beam-to-shell)和樑元素對樑元素(beam-to-beam)的接觸問題。 |
| |
| 針對外形變化太大的分析，例如鍛造、擠製和橡膠產品變形等，ANSYS Structural可採用網格重劃(rezoning)技術，防止元素過度扭曲所產生的發散問題。 |
| |
許多工程問題並無法單純簡化為線性問題，例如連接器端子變形、IC封裝之錫球變形、塑性加工、橡膠產品等，這時採用ANSYS Structural的結構非線性分析，是最佳的選擇。 |

| ANSYS Structural與CAD的整合 |
| |
| ANSYS Structural可搭配ANSYS Geometry Interfaces與ANSYS Workbench，進行CAE/CAD整合。ANSYS Workbench為新一代的ANSYS操作界面，有別於傳統界面，下圖為兩者的比較： |

| ANSYS Geometry Interfaces是ANSYS與CAD系統之間的介面，可將CAD軟體的實體模型直接讀入ANSYS，再進行分析，ANSYS Geometry Interfaces可支援的CAD軟體與檔案格式如下： |
| |
1. CAD System Integration：Autodesk Inventor / MDT, CATIA v4 and v5, Pro/ENGINEER, Solid Edge, SolidWorks, Unigraphics, VX Cad, Other CAD.
2. Neutral Formats : IGES, Parasolid, SAT. |
| |
| 不論是ANSYS Workbench界面或是ANSYS傳統界面，均可採用ANSYS Geometry Interfaces完成設計階段與分析階段之整合。 |
