在这项工作中,提出了一种利用修剪的 CAD 曲面进行分析的新方法。该方法涉及额外的映射步骤,其吸引力源于其简单性以及易于在现有有限元 (FEM) 或边界元 (BEM) 软件中实现。该方法首先通过结构力学中的经典算例进行了验证。然后提出了两个实际应用,一个使用有限元法,另一个使用边界元法,表明了该方法的适用性。
In this work a novel method for the analysis with trimmed CAD surfaces is presented. The method involves an additional mapping step and the attraction stems from its simplicity and ease of implementation into existing Finite Element (FEM) or Boundary Element (BEM) software. The method is first verified with classical test examples in structural mechanics. Then two practical applications are presented one using the FEM, the other the BEM, that show the applicability of the method.
