目前三维的混凝土建模很少见，随机球形骨料在受限空间（球体）随机分布模型,本人自己编写，具有原创性。动画显示建模过程。三种粒径不同的骨料随机分布。模拟混凝土材料的过程。有助于后续有限元计算。(Random spherical aggregate in the restricted space (sphere) random distribution model, I write it myself, with originality. Animation shows the modeling process. Three kinds of aggregates with different particle sizes are randomly distributed. The process of simulating the concrete material. It is helpful to the subsequent finite element calculation.)

For the model of indoor air distribution tuyere proposed by Professor Zhang Tengfei, this paper is UDF code for fluent simulation.

说明：  顶盖驱动流是不可压缩黏性的典型流动，可以用来检验各种数值算法计算精度和可靠性，目前尚不能求得它的解析解。基于Fortran 编程，采用 SIMPLE 算法求解二维方腔流动，得到流动达到稳定状态时各物理量的分布。(Lid-driven cavity flow is an incompressible viscous flow, which can be used to test the accuracy and reliability of various numerical algorithms. In this paper, based on the Fortran programming, SIMPLE algorithm was used to solve the lid-driven cavity flow. The distribution of physical quantities in the stable state was obtained.)
