XFlow为高保真计算流体动力学 (CFD) 应用程序提供基于粒子的 Lattice-Boltzmann 技术，作为 SIMULIA 流体模拟产品组合的一部分。

在现代竞争激烈的产品创新世界中，行业需要对其产品在极端条件下的真实行为进行复杂的模拟；例如车辆涉水、动力系统润滑和关键飞行操作。

XFlow 的最先进技术使用户能够处理复杂的 CFD 工作流程，包括具有真实移动几何形状、复杂多相流、自由表面流和流固耦合的高频瞬态模拟。

其自动晶格生成和自适应细化功能最大限度地减少了用户输入，从而减少了网格划分和预处理阶段的时间和精力。这使工程师能够将大部分精力集中在设计迭代和优化上。

使用 XFlow 的离散化方法，表面复杂性也不是限制因素。底层晶格可以通过一小组参数进行控制；晶格可以容忍输入几何的质量并适应移动部件的存在。

高级渲染功能提供逼真的可视化，以更深入地了解流动和热性能。XFlow 的独特功能使公司能够减少物理测试，同时更快地做出更好的设计决策。

The Dassault Systèmes development team is pleased to announce the availability of XFlow 2020x Refresh 1 (Build 110.08) is a powerful Computational Fluid Dynamics (CFD) software designed for engineering analysis.

XFlow 2020x Refresh 1 (Build 110.08), January 9th, 2020

New Features
– Conjugate heat transfer is now available withtheimmersed-boundary method.
– New thermal coating option for conjugate heat transfer solids.
– Options in the Preferences to disable the resizing of wind tunnel when importing a larger geometry and for the automatic zoom at geometry importation.
– The animation folder is automatically set to simulation folder by default, and can be set to a custom folder.
Improvements
– Negative HTC values for low Prandtl numbers are avoided with the isothermal model.
– Temperature is now available with surface/volume solver integrals.
– The volume heat generation is now available for Conjugate Heat Transfer solids that have boundary conditions applied on different surface groups.
– The surface fields are now correctly plotted in regions where VOF = 0 in multiphase simulations.
– Number of CPU used for domain generation is half the maximum number of CPU when no /maxcpu=N option is passed, with a maximum of 6 CPU. This is to improve scalability.
Bug fixes
– Some memory consumptionissues during post-processinghave been fixed when geometries with boundary conditions disabled are used in the project.
– Other languages support is now fixed.
– Remaining computation time in the process manager is shown correctly.
– Default vertical axis is now Y-axis when importing CATpart and CATproduct.
– Educational licenses behavior is now correct

XFlow offers particle-based Lattice-Boltzmann technology for high fidelity Computational Fluid Dynamics (CFD) applications as a part of SIMULIA’s Fluids Simulation portfolio.

In the modern competitive world of product innovation, industries demand the complex simulation of their product’s real-world behavior under extreme conditions; such as vehicles wading, powertrain lubrication and critical flight maneuvers.

The state-of-the-art technology of XFlow enables users to address complex CFD workflows involving high frequency transient simulations with real moving geometries, complex multiphase flows, free surface flows and fluid-structure interactions.

Its automatic lattice generation and adaptive refinement capabilities minimize user inputs thereby reducing time and effort in the meshing and pre-processing phase. This enables engineers to focus the majority of their efforts on design iteration and optimization.

With XFlow’s discretization approach, surface complexity is also not a limiting factor. The underlying lattice can be controlled with a small set of parameters; the lattice is tolerant to the quality of the input geometry and adapts to the presence of moving parts.

Advanced rendering capabilities provide realistic visualization to gain deeper insight into flow and thermal performance. XFlow’s unique capabilities enable companies to reduce physical testing while making to make better design decisions faster.
