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 to version 2.4.21. As with all new versions, this release includes fixes to various user-reported issues from the previous release, providing an overall more stable experience.
About CONVERGE CFD. CONVERGE is a revolutionary computational fluid dynamics (CFD) program thateliminates the grid generation bottleneck from the simulation process. CONVERGE wasdeveloped by engine simulation experts and is straightforward to use for both engine andnon-engine simulations. Unlike many CFD programs, CONVERGE automaticallygenerates a perfectly orthogonal, structured grid at runtimebased on simple, user-definedgrid control parameters. This grid generation method completely eliminates the need tomanually generate a grid. In addition, CONVERGE offers many other features to expeditethe setup process and to ensure that your simulations are as computationally efficient aspossible.
CONVERGE CFD software comprised of the CONVERGE solver, the CONVERGE Studio graphical user interface (GUI), and CONVERGE chemistry tools.
CONVERGE Solver
The CONVERGE solver is designed for solving reacting flows in systems with complex geometries and moving parts. One of the key features of CONVERGE is ‘autonomous meshing’, in which CONVERGE automatically creates and refines the computational mesh, thereby taking the meshing process out of the users’ hands. CONVERGE’s autonomous meshing features include automatic mesh generation and Adaptive Mesh Refinement.
CONVERGE Studio
The CONVERGE Studio GUI includes both pre- and post-processing tools for the CONVERGE solver. Before running a CFD simulation in CONVERGE, the CONVERGE Studio pre-processing tools can be used to prepare the surface geometry, configure input files, and set up the reaction mechanism. After running a CONVERGE simulation, the line plotting module and the 3D visualization module in CONVERGE Studio can be used to visualize and interpret the simulation results.
CONVERGE Chemistry Tools
CONVERGE includes a number of chemistry tools for the SAGE detailed chemistry solver. These tools include the 0D solver, 1D solver, mechanism reduction, mechanism merge, mechanism tuning, and surrogate blender. The 0D, or autoignition, solver calculates ignition delay for a given set of fuel parameters, e.g., temperature, pressure, equivalence ratio. The 1D solver calculates laminar flame speeds.To reduce computational time, the mechanism reduction tool eliminates species and reactions that have the least effect on the simulation results. The mechanism merge tool combines two reaction mechanisms into one,and the mechanism tuning tool optimizes reaction mechanisms to meet specified performance targets. In CONVERGE Studio, the surrogate blender tool approximates real fuels through multi-component surrogates whose properties match those of the target fuel.
Looking to predict urea decomposition, selective catalytic reduction (SCR), soot quantities, or NOx emissions with confidence? Look no further. CONVERGE CFD easily handles complex moving geometries, and its adaptive mesh refinement (AMR) automatically ensures that you can capture data where it really is.
