摘要:

本文提出了一种利用修剪NURBS片进行边界元法仿真的新方法。该方法的优势在于高效性和易于实现。通过双映射实现修剪NURBS分析,将边界未知变量的变化指定在局部坐标系中,与几何描述完全独立。该方法在支洞问题中进行了测试,并与传统方法的结果进行了比较。结论表明,该方法在未知变量数量和所需努力方面具有优势。

英文摘要:

A novel approach to the simulation with the boundary element method using trimmed NURBS patches is presented. The advantage of this approach is its efficiency and easy implementation. The analysis with trimmed NURBS is achieved by double mapping. The variation of the unknowns on the boundary is specified in a local coordinate system and is completely independent of the description of the geometry. The method is tested on a branched tunnel and the results compared with those obtained from a conventional analysis. The conclusion is that the proposed approach is superior in terms of number of unknowns and effort required.
