Abstract
This report focuses on CFD-calculations using parallel processors carried out with the software Fire Dynamics Simulator (FDS). From a users point of view the advantages and disadvantages with parallel CFD-calculations were analyzed and evaluated. A simplified me-thod for quantitative evaluation was developed with guidance from ASTM E 1355 whereu-pon relative differences between serial reference scenarios and corresponding parallel cal-culations were quantified and evaluated. Also, aspects like wall clock time speed-ups and the use of hardware resources were evaluated. The purpose of the project was to identify possible sources of error and assess calculation speed-ups as a consequence of distributing calculations over multiple processors... (More)
