CONVERGE是美国Convergent Science Inc.（CSI）开发的革新性的热流体分析软件，它解决了网格生成这一CFD模拟中一个重要障碍。高效求解器配合自动网格生成功能极大缩短了计算时间。
自动网格生成功能不仅缩短计算时间，也适用于任何复杂形状的几何结构和类似阀门的运动边界。这种边界处理的实用性比其他软件显著提高。
CONVERGE自动生成正交六面体网格，并且还具有动态网格加密，负荷平衡功能，以取得较高计算精度。求解复杂现象的物理模型有喷雾模型，RANS 和LES湍流模型，燃烧模型，广泛应用于内燃机的共轭传热模型，流固耦合模型，辐射模型和VOF模型。
特别对于燃烧，除了经验模型，还有详细化学反应计算和机理简化功能，以前很难计算的详细化学机理现在可以计算。
Convergent Science has updated its CONVERGE CFD (computational fluid dynamics) software. This release combines the package’s automated meshing function with new facilities for solving surface chemistry and molten-solid reactions.
The automatic meshing function is one of the cornerstones of the software, explained Convergent Science marketing director Rob Kaczmarek.
Where Converge differs from most other CFD packages is that the meshing function is fully integrated and coupled into the flow and chemistry solver.
It creates a new mesh for every time step, which allows critical areas of the mesh to be refined dynamically during runtime (adaptive mesh refinement) – for instance focusing on the mesh around the flame front as it propagates out across the cylinder.
The new surface chemistry solver means that the package can now model the reaction between a solid surface and a gas-phase species on both walls and porous media, while the molten-solid capability is aimed primarily at modelling the depletion of urea in diesel after treatment systems.
The strength of the new package is combining these chemistry models with its unique approach of fully coupling the mesh with the flow and chemistry solvers, automating its generation at runtime and then refining the mesh when and where it is needed.
PSA Peugeot Citroën has been using past iterations of the package for more than four years and the group’s manager for the modelling of energetic and combustion systems, Clément Dumand said this self-meshing capability has substantially improved productivity.
