“…In order to overcome this problem, there have been several works (Serikov et al, 2009; Wu and FDS Team, 2009;Sato et al, 2009;Bekar and Evans, 2009;Fleurot and Searson, 2011) to take advantage of modeling capability of the computer aided design (CAD) system. McCARD has the capability to directly utilize the CAD geometry data by converting the CAD model to the internal data structure of the constructive solid geometry (CSG) to be used by the code with help of a CAD kernel, OpenCASCADE (OpenCASCADE™).…”
