A first-in-class Simulation Platform for Complex Multiphase Flow

TransAT© is a versatile fluid-flow simulation platform (CFD/CMFD) using the Immersed Surfaces Technology for multi-dimensional meshing

The platform is particularly suitable for multiphase flows using tailored predictive techniques augmented by a wide-range of models accounting for complex physics

TransAT can be deployed under Linux and Windows operating systems, and is parallelized using MPI parallel protocol for HPC infinite-band systems

TransAT can be employed in various engineering verticals, including oil & gas, energy systems, chemical and process engineering, hydraulics and waste water, transportation and environment
