代码说明:

  有限元求解柏松方程。本文采用FORTRAN语言编制程序。程序中大部分变量采用有名公共区存储方式存储,这样可以减少内存占用量。 IFG:生成有限元网格信息,即元素节点局部编码与总体编码对照表,节点实际坐标,边界节点编码与边界点上的已知值 GKD:生成总刚一维存储对角元的地址,计算总刚一维存储长度 FIXP:设置已知节点函数值 GK(NI,NJ,ADJ,AIJ):单元刚度矩阵计算 GF(NI,N,M,LE,YI,FE):单元列阵的计算 AK(I,J,AIJ):总刚度矩阵元素迭加 QEB:总刚度矩阵和总列阵合成 BDE:边界条件处理 SOLGS:Gauss-Seidel迭代法求解方程组 UDIFF(NI,NFLAG,UDIF,LE,ADJ):标准元素内形状函数导数计算 DIFF:节点上 , 加权平均 (In this program, FEM was used to solve the possion equation. It is implemented through FORTRAN)

    下面我们将给出一些基于Galerkin有限元法的微型泵模拟结果,模拟过程在商业软件COMSOL Multiphysics 3.2中实现。数值求解采用压力修正算法——SIMPLE,它首先假设一个压力场,然后通过求解不可压缩流动的Navier-Stokes方程得到速度场。这些速度不需要满足Possion型连续方程,所以对压力场的修正也带来速度场的修正,最终满足质量守恒。求解速度场的同时计算电势场方程。这会得到Lorentz力,然后将其反馈回N-S方程并作为体积力处理。连续耦合Lorentz力和速度场直到Newton迭代收敛。 (Below we will give some micro-pump simulation results based on the Galerkin finite element method, the simulation process in the commercial software COMSOL Multiphysics 3.2. The numerical solution of pressure correction algorithm- the SIMPLE, it begins by assuming a pressure field, and then by solving the incompressible Navier-Stokes equations, the velocity field. These velocities do not need to satisfy the continuity equation of Possion type pressure field correction to bring the amendment of the velocity field, and ultimately to meet the conservation of mass. Solving the velocity field at the same time to calculate the potential field equations. This will be the Lorentz force, and then fed back to the NS equations and processing as a volume force. Continuous coupling of the Lorentz force and the velocity field until the Newton iteration convergence.)
