CPACS for Rectangular Box Wing

The Datasets represents a common use case in literature used for composite optimisation. A rectangular profile is defined, greater than the desired structure. Spars, ribs and shell cells define the investigated struture and only for them cells are defined.
The following references are build up as CPACS Dataset:

Additionally a version with stiffened covers is created based on number 3.

本数据集为复合材料优化（Composite Optimisation）领域文献中常见的应用场景。首先定义一个大于目标结构的矩形轮廓，研究结构由翼梁（spar）、肋（rib）与蒙皮单元（shell cell）构成，且仅为这些构件定义单元。
