Real time visualization of flow fields using open GL system

We, introduce a newly developed flow visualization system. This system was designed so that we could observe progress in a flow calculation. In particular, a visualization process of this system automatically reads renewal data from a flow calculation process in a specific mode. This faculty could not have been realized on a conventional PC system whose OS was based on a 16 bit process. The present visualization system built on a 32 bit OS, Windows NT, removes this problem by means of a preemptive multi-task facil i ty equipped with the OS. Furthermore, an improvement of MPU performance and Open GL realize a true real time visualization in this system. In this paper, we discuss prospects of a real time flow simulation from some examples of an actual use and its operation time.
