Slashing unsteady data size with XDB workflow results in huge productivity gains

Unsteady rotorcraft CFD analysis can generate mountains of grid and solution data, making transfer across networks time-consuming and often impractcal. Further the large data places a strain on available storage resources. XDB-based CFD workflow, made possible by FieldView 13, enables analysts to significantly reduce data size and better utilize remote HPC systems, achieving dramatic performance and productivity gains in the process. The means getting to answers faster and more cost-effectively than ever before.
This technical case study outlines XDB-based workflow approaches for an unsteady rotorcraft simulation. FieldView post-processed the transient data remotely, outputting XDB (eXtract database) files that reduced the size of the dataset from 36.4GB to 127.5MB – a reduction factor of 286. Transftering only these smaller files to a remote workstation for interactive review, high quality and extremely fast graphics allowed the analyst to view the time-dependent simulation results at more than 80 frames per second while sweeping through the data, rotating, panning and zooming.
