All the parts of the tNavigator workflow share a common proprietary internal data storage system, a super-scalable parallel numerical engine, a data input/output mechanism and a graphical user interface. tNavigator supports the METRIC, LAB, FIELD systems of units. tNavigator is a multiplatform software application written in C++; it can be installed on Linux, Windows 64-bit OS and run on systems with shared and distributed memory layouts both as a console and a GUI (local or remote).
For a comfortable experience with the GUI version, Full HD resolution (1920×1080) is recommended. All modules with a graphical interface are supported only when the NVIDIA driver for the graphics card is loaded and configured. Integrated graphics cards are not recommended. tNavigator runs on workstations and clusters. A cloud-based solution with full GUI capabilities via a remote desktop is also available.
tNavigator contains the following 17 functional modules licensed separately:
- Geology Designer
- Mining Designer
- Seismic
- Geosteering
- Geomechanics
- Model Designer
- Network Designer
- Well Designer
- Material Balance Analyzer
- PVT Designer
- Fracture Simulator
- RP Designer
- Black Oil Simulator
- Compositional Simulator
- Thermal Simulator
- AHM & Uncertainty (Assisted History Matching, optimization and uncertainty analysis)
- Graphical User Interface
Operating system
The tNavigator version for Linux OS generally operates about 10 % faster than the version for Windows on the same hardware platform configuration.
CPU
To accelerate calculations, it is recommended to use dual-processor systems, as the number of memory channels is doubled. Processors with a larger number of physical computing cores provide a greater performance boost than processors with a higher frequency but fewer cores. Recommended processors are listed in the document linked below.
RAM
When planning a hardware configuration, it is essential to use all available memory channels; otherwise, system performance may suffer. The necessary RAM depends on the size and type of the model being calculated: Black Oil requires 3 KB for each active cell, while a compositional model requires 1 KB for each component for each active cell. In most cases, an optimal memory capacity for modern dual-processor systems is 128–256 GB.
GPU
tNavigator supports NVIDIA adapters starting from the Pascal generation (Tesla P/Quadro P/GTX 10xx/TITAN X series). Adding a second GPU to the system accelerates calculations by about 20 %. The amount of required video memory is calculated in the same way as for RAM. Please note that NVIDIA prohibits the use of GeForce and TITAN GPUs in data centers. Recommended GPUs are presented in the full document linked below.
