Development and application of SN Auto-Modeling Tool SNAM 2.1

SNAM is the abbreviation of “SN Auto-Modeling”, which is a CAD interface program for SN codes based on CAD technology. Making full use of CAD technology is SNAM's major characteristic. In brief, CAD technology is utilized in the following two ways: firstly, SNAM makes it possible to create SN geometry models in convenient CAD environments; secondly, the creation of SN geometry models is remarkably accelerated by inheriting existing CAD models. Main capabilities of SNAM include: (1) geometry modeling; (2) ability to convert CAD models into SN geometry models; (3) ability to convert SN geometry models into CAD models. This paper describes the system architecture and main features of SNAM. SNAM-based SN modeling process and preliminary applications for real-world engineering models, such as ITER and EAST, are also presented.
