Next Limit Technologies is a computer software company headquartered in Madrid, Spain. Founded in 1998 by engineers Victor Gonzalez and Ignacio Vargas[1] the firm researches and develops innovative technologies in the field of digital simulation and visualization. This software can be applied to a wide variety of professional fields spanning from engineering to digital content.[2]

The company's projects include: Maxwell Render (a light simulator and physically correct render engine), XFlow (engineering software for fluid and wind tunnel simulation), RealFlow (a dynamics and fluid simulator for film production) and CaronteFX (a physically-based animation editor extension for Unity (game engine)). RealFlow has been used in the production of films such as: The Lord of the Rings: The Return of the King, 300, Charlie and the Chocolate Factory, Robots, The Girl with the Dragon Tattoo, and others.[3]

Research and Development[edit]

Next Limit has actively participated in various research projects throughout Europe as well as Spain. It is currently the leader of the European project, SAFECITI (Safe Citizen),[4] which aims to create a simulation system for analysts that would predict the behavior of large crowds in urban environments in moments of panic, violence, or catastrophes. The system is based on serious game technology and is designed as a training platform. Other European projects that Next Limit has actively participated in are: PRISM,[5] Skycoat[6] and COELUX.[7] COELUX is responsible for the production of a window with an optics system based on nanotechnology that can reproduce natural light and the appearance of solar and sky light. This technology is implemented in closed spaces that lack an exterior facing window.[8]

In Spain, Next Limit has participated in biotechnology research to simulate the heart as a complex fluid structural system.[9]
