In the present study, a method by which to incorporate a set of linear multipoint constraints (MPC) into the BDD method is proposed. In this method, when an MPC is enforced on the internal degrees of freedom (D
2) MPC 多点约束 1. "PATRAN" is used to create a canopy FEM for an aircraft using MPC to simulate the flexible attachment between plexiglass and frame. 采用PATRAN建立了某型飞机座舱盖有限元模型,用多点约束模拟玻璃边缘与骨架及弧框之间的软连接。3) constraint equation 约束方程 1. Based on ...

Then, improved implementation techniques for the BDD-MPC method are proposed. The computation speed of the projection procedure in the conjugate projected gradient method is improved using the block diagonal structure of the constraint matrix. The parallel solution procedure for the coarse-grid problem ...
In the paper, the methods and characteristics of SOLID-SHELL unit with the application of ANSYS constraint equations method and the MPC law are discussed, and compared the shell - solid element with the whole solid element modeling combined the results, it draw a conclusion that MPC law is ...
