tNavigator软件是一款高效精准、功能齐全的油藏数值模拟软件。其以计算速度著称，可以实现超大（千万网格节点）型油藏模型数值模拟运算，使得无粗化精细地质模型和超大规模模型运算成为可能。软件功能齐全，可实现黑油、组分、热采、流线、化学驱模拟。软件图形用户界面丰富，操作简洁，易于上手；灵活专业，运算过程和结果可以实时显示，可以帮助油藏工程师及时监测历史拟合情况，提高历史拟合效率。软件数据兼容性好，可直接加载常规数模软件工区运算，应用常规软件前后处理模块准备或查看数据。
tNavigator软件是俄罗斯软件公司Rock Flow Dynamics (RFD)公司与Intel合作，经多年研发、目前已在全球各大油公司得到广泛应用的新一代高效数值模拟技术。它是行业内首款也是唯一的一款将全三维交互用户界面与创纪录的超级并行计算引擎动态结合的行业领先产品。它的出现，使得超大网格节点（千万至千兆级有效网格）油藏模型数值模拟成为可能，成为行业内革命性的新一代数值模拟技术产品。
2017年4月，GPU级数值模拟器17.1版本行业首发，引领新一代高效精准数模技术，是行业中效率最高的精准数值模拟技术，实现精细模型运算常态化。
In tNavigator 17.1 kernel new options are supported for the following model formats: E100,E300, MORE, IMEX, STARS, GEM.
Reservoir Coupling:
Dynamic restarts are available in graphical interface, options –continue, –restart are
available for console, automatic restarts. Restart MASTER and SLAVE models can be
used.
For models in E100 and E300 formats:
The possibility to set the salt concentration in the injection stream via user defined
quantity UDQ (2-nd parameter of the keyword WSALT).
The possibility to set group name, whose produced polymer (salt) concentration will
be used in the injection stream for the well (4-th and 5-th parameters of the keyword
WPOLYMER).
Artificial lift quantity (ALQ) value can be set and used in the pressure loss calculations
for the group’s pipeline (4-th parameter of the keyword GRUPNET).
CIRR mode is available to set injectivity multiplier for injectors. Injectivity increase
is not reversed for all connections. Connections continue working with its maximum
attained injectivity multiplier (4-the parameter of the keyword WINJMULT).
The possibility to set the grid block pressure limit for well rate cutback or for reversing
the cutback process (8-th and 9-th parameters of the keyword WCUTBACK).
The algorithm of surface network calculation has been updated.
