各位好,我现在正做钢管混凝土N型节点的滞回曲线分析,但是其中的接触设置弹出如下错误: *** WARNING *** CP = 1626.984 TIME= 12:38:16 All selected contact pairs are initially open. Rigid body motion can occur. You may use auto CNOF/ICONT by setting KEYOPT(5) to close
*** WARNING *** CP = 1626.984 TIME= 12:38:16
All selected contact pairs are initially open. Rigid body motion can
occur. You may use auto CNOF/ICONT by setting KEYOPT(5) to close
small gaps.
现在不知道CNOF/ICONT该怎么设置。
我的钢管是shell181单元,管厚6mm;混凝土取solid65单元。接触单元分别是170和174单元。现在的情况是混凝土的外表面离钢管轴线是3mm,不知道这样对不对?那CNOF/ICONT又如何设置?
