Project Title:

A SOFTWARE ARCHITECTURE FOR EFFICIENT VISUALIZATION OF LARGE, UNSTEADY CFD RESULTS

Technical Abstract:

Modern Computational Fluid Dynamics (CFD) solutions routinely generate 3D grid and solution data sets that exceed many hundreds of megabytes. This problem is further exacerbated when the flow under study is transient (time-varying), in which case they may exceed 100 gigabytes in size. Visualization of these results can be very difficult and time consuming, due to limitations in (a) processing power, memory and graphics speeds of workstations and computers and (b) current software tools used for post-processing. The offeror proposes herein to create and utilize innovative software techniques to provide significant improvements in the speed and convenience of visualizing these large CFD data sets. The approach is based on the use of Data Pre-processing, a Database Access Model and Subfield Extraction to create an access methodology that makes tradeoffs between time and space, to optimize the usage of computing and visualization hardware. Such an access methodology is applicable to both structured and unstructured grid data and can be subsequently integrated into existing and future visualization environments so that the benefits may be widely utilized. High performance, convenient visualization of such data will allow NASA to increase the pace at which transient, complex aerodynamic, aerothermodynamic and aeroacoustic phenomena are understood. _

Potential Commercial Applications:

Development of software toolkits and workbenches for the visualization of large, transient field data such as CFD and structural analysis solutions and remote sensor data. _
