GT-CONVERGE

GT-CONVERGE is a 3D CFD module which complements GT-SUITE and advances your plant and system level simulations. Importantly, it empowers non 3D-CFD experts, through features like autonomous meshing and dedicated easy-to-use simulation setup.

A product of joint efforts between GT and Convergent Science, GT-CONVERGE is fully integrated into GT-SUITE and allows you to investigate and understand components of your system whenever 3D flow effects are predominant.  GT-CONVERGE enhances the GT-SUITE portfolio, further strengthening its 1D/3D synergistic capabilities. The result is a compelling turnkey solution, from component to system and validation.

Typical Use Cases of GT-CONVERGE Applications

Transient 1D and 3D co-simulation

When portions of a system require 3D resolution, GT-SUITE offers the ability to tightly co-simulate the 1D and 3D domains. One widely used example is the impact of intake manifold geometry on transient EGR distribution and mixing. GT-CONVERGE captures spatial distribution of EGR concentrations, complementing the GT-SUITE 1D flow solution.

Characterize pressure drop & heat transfer in complex components

Use the GT-CONVERGE steady-state solver to rapidly characterize flow characteristics such as component pressure drop and heat transfer.  The resulting data tables are seamlessly exported into GT-SUITE system-level models, enabling fast and accurate results of flow systems.

Conjugate heat transfer

GT-SUITE includes a native 3D thermal finite element solution used to calculate the structure temperatures.  With GT-CONVERGE, one can simulate the conjugate heat transfer between CFD flow fields and these structures (this in addition to the capability for conjugate heat transfer between 1D flow networks and structures).   An example of the former is an air-cooled battery shown below, where  the electro-chemical solution of GT-AutoLion3D is integrated to capture distribution of heat generation, combined aging, and SOH within the cells.

Generate flow fields for real-time cabin comfort simulation

GT-SUITE offers advanced cabin solutions for fast and accurate prediction of passenger comfort. This approach relies on import of 3D CFD flow fields, which can come from a variety of commercial CFD tools.  One of them is GT-CONVERGE, which provides the extra benefit by being fully integrated into the model building workflows, thus forming a seamless tool chain in one software platform to accomplish your simulation tasks easily, on time, with high quality.
