多相流cfd程序,用fortran实现,有多流体和dem计算功能,当然还有其它更多功能(MFiX is a general-purpose computer code developed at the National Energy Technology Laboratory (NETL) for describing the hydrodynamics, heat transfer and chemical reactions in fluid-solids systems. It has been used for describing bubbling and circulating fluidized beds and spouted beds. MFiX calculations give transient data on the three-dimensional distribution of pressure, velocity, temperature, and species mass fractions. MFiX code is based on a generally accepted set of multiphase flow equations. The code is used as a "test-stand" for testing and developing multiphase flow constitutive equations.)

假设有一个能装入总体积为T的背包和n件体积分别为w1 , w2 , … , wn 的物品,能否从n件物品中挑选若干件恰好装满背包,即使w1 +w2 + … + wn=T,要求找出所有满足上述条件的解。例如:当T=10,各件物品的体积{1,8,4,3,5,2}时,可找到下列4组解:(1,4,3,2),(1,4,5),(8,2),(3,5,2)。
[需求分析](Suppose there are a load of the backpack of the total volume of T and n volumes were w1, w2, ... wn items, whether selected from n items a number of exactly filled backpack, even if w1+w2+ ...+ wn = T, find out the solution of all the above conditions are met. For example: when T = 10, the volume of items {1,8,4,3,5,2}, can be found in the following four solutions: (1,4,3,2), (1,4,5 ), (8,2), (3,5,2). [Needs Analysis])
