Development Of The CAD Software For Microfluidic Systems

Microfluidic is only a supplementary of the nano-technology revolution at first.After experiencing propagandized wantonly and desolate,it has finally realized the commercialization production. Microfluidic was initially called "lab-on-a-chip" in USA. With the breakthrough progress of material science,micro and nanofabrication technology and microelectronics,Microfluidic has been developed quickly.The design method of Microfluidic dropped far behind the manufacturing technology.Hitherto there is no Microfluidic CAD tool suitable for all Microfluidic system.Because of lacking Microfluidic CAD tool , developers can only use the software which only suitable for one Microfluidic system,or the commercial CAD tools like CoventorWare,CFD-ACE+ and COMSOL Multiphysics.Then manufacture the prototype directly and determined by experiment,then remodify the parameter according to the result.This method is Time-consuming.This paper analyses the traditional design method of the Microfluidic,proposes a new CAD design method.using the CAD tool to make the numerical simulation and parameter optimization of the Microfluidic system.Then manufacture the prototype according to the optimization result,this method can reduce the iteration number and shorten the development period.A new software system is presented in this paper.Recently,the parameter optimization of the Microfluidic system has gradually become research focus.Developers try to improve the performance of the Microfluidic by parameter optimization of the Microfluidic system.In this paper we analyze the parameter optimization of the DNA separation Microfluidic system.Using the CAD tools to simulate the Microfluidic system,and analyze the connection between parameters and the effects of the DNA stretching.then realize the parameter optimization of the DNA separation Microfluidic system.After the appearance of the computer,people never stop the attempt to improve its calculation speed.Parallel computing is an effective method.In this paper,we analyze the parallel computing,proposed a parallel algorithm based on Multi-Core CPU System,reduce the computing time of the parameter optimization of the DNA separation Microfluidic system.It is of great importance for scientists and researchers to use The CAD software presented in this paper to increase the efficiency.The optimization method and parallel algorithm can be used to study other Microfluidic systems.
