在ANSYS接触分析中KEYOPT(9) = 4与KEYOPT(9) = 6区别到底在哪？
具体问题一：contact surface penetration (CNOF)与contact offset (CNOF) 是同一个概念么？
具体问题二：KEYOPT(9) = 4忽略the penetration due to geometry，但考虑the gap due to geometry；而KEYOPT(9) = 6即忽略the penetration due to geometry又忽略the gap due to geometry？

以下是ANSYS14.5帮助原文摘录：
1.To ramp the defined contact surface penetration (CNOF), but ignore the penetration due to geometry, set KEYOPT(9) = 4. This option works if initial penetration is detected for certain contact definitions (KEYOPT(12) = 0, 1, 2, 3, or 6).
2.To ramp the defined contact offset (CNOF) but ignore the penetration or gap due to geometry, set KEYOPT(9) = 6. This option works as long as the contact is detected within the pinball region (near-field or closed contact). For a bonded contact definition with KEYOPT(12) = 4 or 5, setting KEYOPT(9) = 4 is equivalent to setting KEYOPT(9) = 6.
