利用Visualization模块中的“单元质量检查”功能,监控雅可比行列式、长宽比等指标,结合XFEM(扩展有限元)标记失效单元。 4. 硬件资源平衡 对于涉及ALE(任意拉格朗日-欧拉)自适应网格的重拓扑分析,合理分配CPU与内存资源,避免因计算资源不足导致中断。 网格扭曲问题本质上是物理过程与数值离散化矛盾的体现。Abaqus为解决此类...
若仅仅定义两个part间的面对面接触(surface to surface contact),不收敛,后处理中可见特征边对面的穿透…… Figure-9:接触对模型及结果 改善此类接触收敛问题,我们的建议方案为: 1、通用接触方案 修改为接触设置为通用接触(General contact),接触属性不变,考虑接触分离时的不稳定状况分析步中加入自动稳定,分析顺利收...
(Job Manager),弹出对话框Job Manager,点击Submit提交分析,看到对话框中的Status(状态)提示依次变为Submitted,Running和Completed,这表示对模型的分析已经成。点击此对话框中的Results(分析结果),自动进人Visualization可视化模块。求解结果后处理 选择工具栏中所需的场变量,即可在视图区中显示该场变量云图。
Vibratory rollers are generally used in the process of highway subgrade compaction. In the paper, the vibratory roller—subgrade finite element model was established to simulate the field construction by using ABAQUS. We used Hilbert–Huang Transform to
