Abstract A new platform software named JUSMAR-MANS based on JASMIN was developed for the massively parallel numerical simulation on compressible multimedia multiphase flow under complex conditions. Different from the traditional “chimney” program research and development (r&d) pattern, the MANS who adopted the “platform” r&d pattern provides a way by which the users can rapidly and conveniently customize personalized high-credibility program of multimedium without considering in numerical discrete and parallel computing. MANS has the following advantages: 1) Decoupling of disciplines: In architecture design, physical modeling, numerical discreting, parallel computing are separated from each other and concept shielding so that the high barriers of program r&d caused by interdisciplinary are broken down. 2) Expandability: enables to easily extend new physical models and numerical schemes based on single point/element interfaces. 3) Rapid customization: enable to quickly assemble personalized program based on various models and algorithms libraries integrated by MANS. Based on MANS, it only takes serial code within a few days to obtain a well-posed large - scale multimedium simulation, which greatly reduce the complexity of software r&d for compressible multimedium flow.
