In the numerical calculation of dynamic flow field in high voltage circuit breaker arc chamber

it is necessary to quickly and accurately extract massive data of flow field generated in the ANSYS simulation relating with dynamic mesh

and further draw the curves of the relevant physical parameters versus time. In this paper

commercial software ANSYS CFD-POST and MATLAB are integrated for secondary development of fluid simulation post process to develop a program for relevant data extraction.The dynamic flow field calculation result of a high voltage circuit breaker arc chamber in practice is taken as an example to verify the feasibility and efficiency of the developed program

in which geometric position and physical parameters change during post process. It shows that this program can overcome the difficulty of massive data extraction in the post process of dynamic flow field

avoid huge extra work

and realize parameterization and automation in data processing.
