六面体

In this paper, we put forward a 2.5D model based on the hexahedron and developed an inversion method of constraint gravity-vertical fault. The inversion result is better than that the 2D model through the model tests. Based on this model, we quantitatively interpreted the Bouguer gravity anomaly of the Sierra Nevada Region in the USA.

本文从六面体模型出发，将二度体模型修改为似二度体模型，建立了一个带约束的重力－垂直断层反演模型，经过理论模型试验，证明效果要优于二度体模型的反演结果，在此基础上对美国内华达州的圣安德烈斯地区的布格重力异常资料做了定量解释。

Meshes are built which mainly are uncontinuous, complete unconstructed hexahedron, partially unconstructed polyhedron, near wall boundary layer mesh is adopted which can fit complicated geometry surface of cooling system well and guarantee mesh quality, in addition partial refinement technology is used to make mesh better in some key location.

网格主体采用非连续的、完全非结构化的六面体，部采用非结构化的多面体网格，对于壁面附近采用边界层网格处理，这样网格既能很好地适应冷却系统复杂的几何表面，又进一步了保证网格质量，另外利用局部加密技术对重点区域进行处理使网格更加完善。

Methods A wet hip joint's sample from corpse was scaned by CT and all images of every cross-section hip joint's layer was obtained, and an hip joint's model was contructed with Unigraphics NX 2.0 and Solid Works 2006 SP 0.0 software. The models were assembled when simulated total hip arthroplasty after total hip joint prosthetic and ischiofemoral ligament model had been constructured. Analysis was done on von Mises stress distribution and amount of total hip component when simulated seated leg-crossing manuver. The bone and metal components were meshed as rigid bodies, composed of three-dimensional, all-quadrilateral rigid body elements, and hip joint capsule ligament was fully three-dimensional, hexahedral continuum elements representations. Results The current form of this ischiofemoral ligament's reconstruction finite element model provided for multi-body contact, large displacement interfacial sliding, large deformation capsule ligament representation, and clearly reflected the real ischiofemoral ligansent's anatomy and biomechanical behavior. The maximum on Mises stresses at the joint interface was more than that fur an otherwise identical hardware-only construct.
