NUMECA HEXPRESS/Hybrid  10.1 | 1.2 Gb

The HEXPRESSTM / Hybrid program appeared on the market as a response to the need of European automotive companies for a fast and efficient mesher (grid builder), with which you can build computational grids for complex topologies in an extremely short time. At the moment, in our opinion, this is the only known tool that allows you to build a grid for calculating both the external and internal aerodynamics of such a complex object as, for example, a car, including the engine compartment and the interior, in one day, starting directly from the “unclean” geometry.



HEXPRESSTM / Hybrid程序出现在市场上,是对欧洲汽车公司对快速高效的网格划分器(网格生成器)的需求的一种回应,您可以用它在极短的时间内构建用于复杂拓扑的计算网格。我们认为,目前,这是唯一已知的工具,可让您构建一个网格来计算复杂物体(例如汽车,包括引擎室和内部空间)的内部和外部空气动力学,在一天之内,直接从“不干净”的几何图形开始。


HEXPRESSTM / Hybrid提供了其啮合技术和原始的啮合方法。预处理分为两个阶段,第一个阶段是在程序的用户界面中处理几何。第二阶段是使用包含网格化参数的文本配置文件从命令行(使用Linux,Unix操作系统的方式)构建网格。网格划分的选项很少,它们很直观。结合GUI原理和使用配置文件在命令行上工作的主要优点是重建网格的速度和自动性,为新的标准几何图形创建新网格的过程被加速了许多倍,从而绕开了通常繁琐的网格设置阶段在用户界面中(您已经有一个现成的配置文件,您需要的一切)HEXPRESSTM / Hybrid中的网格划分过程是完全并行的;默认情况下,它在所有可用的并行计算机处理器内核上运行。
嵌入在HEXPRESSTM / Hybrid中的独特创新技术使您可以为整个沉降域或多个域自动构建六边形共形网格(可以构建四或全十六进制网格),该网格以墙层或如果需要的话,没有它。
HEXPRESSTM / Hybrid offers its meshing technology and its original meshing approach. The preprocessing is divided into two stages, the first is working with geometry in the user interface of the program. The second stage is the launch of building a grid from the command line (in the style of working with Linux, Unix operating systems) using a text configuration file that contains the parameters of the meshing. There are few options for meshing, they are intuitive. The main advantage of combining the GUI philosophy and working on the command line using the configuration file is the speed and automatism in rebuilding grids, the process of creating new grids for new standard geometries is accelerated many times, bypassing the often tedious stage of grid setup in the user interface (you already have there is a ready-made config file and everything you needThe meshing process in HEXPRESSTM / Hybrid is completely parallelized; by default, it runs on all available parallel computer processor cores.
Unique innovative technologies embedded in HEXPRESSTM / Hybrid allow you to automatically build hexadominant, conformal grids (it is possible to build tetra or full hex grids) for the entire settlement domain or several domains, the grid is built with the resolution of the wall layer or without it, if desired.
The key feature of the HEXPRESSTM / Hybrid is that it is not demanding on the cleanliness of the initial geometry and can build a grid for geometries with serious flaws, crevices, etc., which generally reduces the time step of meshing by an order of magnitude when working with real, "unclean" geometries .
HEXPRESSTM / Hybrid has a built-in automatic tool for finding and closing holes, which allows you to start working with almost any geometry that you have been transferred without having the deep knowledge or time to solve the problem in CAD or similar systems.
HEXPRESSTM / Hybrid is an ideal tool for building grids of large dimension, complex geometry topology in the shortest possible time.
Currently, HEXPRESSTM / Hybrid has found its fans in almost all branches of engineering and industry, including such atypical areas as medicine.
NUMECA International is delighted to announce the official release of HEXPRESS and HEXPRESS/Hybrid version 10.1. This solutions use a similar volume-to-surface approach, suppressing the need for a surface mesh. Both systems run in batch or interactive mode and are interfaced to all major commercial CFD codes.


New in HEXPRESS v10

General upgrades in the package
General package upgrades in v10.1:
- FlexLM based license security ID is upgraded to v20;
- Use of Parasolid v32.0.214;

Freeze faces not used for trimming
A cylinder is composed of two flat surfaces, that could be defined as "not used for trimming". But because of the connected and rounded surface of the cylinder, a buffer must still be inserted and propagated on the flat surfaces, leading to the activation of the smoothing as well. To overcome this particular situation that degrades the mesh quality, the new option Freeze faces not used for trimming allows to disable the smoothing on the flat surfaces to freeze them and so to improve the quality.

Improved python commands
The following python commands have been improved to return the status: 1 - success and 0 - fail. In case of failing, all processed parts will be reverted.
- scale_parts()
- rotate_parts()
- translate_parts()

Improved robustness
Several bug corrections have been done to improve:
- the robustness of the rotor-stator calculation.
- trimming condition detection.
- CATIA v6 CAD manipulation.

New in HEXPRESS/Hybrid v10

General upgrades in package
General package upgrades in v10.1:
- FlexLM based license security ID is upgraded to v20;
- Use of Parasolid v32.0.214.

Improved speed and robustness for distributed parallel meshing
The speed and robustness are further improved for distributed parallel meshing.
Customer Benefits
- 1.5X speed-up for mesh generations with both OpenMPI and IntelMPI.

Significant speed-up of mesh generation
The improvements done for the different functionalities below significantly speed up the mesh generation time:
- S2V full tetrahedral mesh generation;
- Viscous layers insertion with the extrusion method;
- the EXACTMESHING keyword.
Customer Benefits
2X to 10X speed-up for the mesh generation with the extrusion viscous layers method, 2X speed-up for S2V full tetrahedral meshing and 1.5X for the mesh generation with the EXACTMESHING keyword.

New OpenFOAM optimizer
A more OpenFOAM dedicated optimizer (OPTIPARAMETER 3.3) is introduced to improve the mesh quality for OpenFOAM meshes. This optimizer improves the skewness, non-orthogonality, and adjacent volume ratio, excluding the optimization for NUMECA quality (OPTIPARAMETER 0). It also performs special optimizations for sharp convex and concave configurations in the viscous layers and additionally splits cells that may produce the OpenFOAM "face pyramid error".
Customer Benefits
- Generates better mesh quality for OpenFOAM simulations.
Known Limitations
- Improvement may not be satisfying for the following configurations:
. very small first cell size of the viscous layers.
. viscous layers near sharp convex and concave dihedral angles (<90 or >270 degrees).
. meshes containing CYLINDRICALMESH, TRANSFORMSELECTIONS and Mesh Transformations keywords.
- The cell splitting technique to avoid the OpenFOAM "face pyramid error" is not performed for full hexahedral meshes with hanging nodes and mixed element meshes inside or close to the buffer type II configurations.

Improved OpenFOAM and CGNS exports
- OpenFOAM
The OpenFOAM meshes are now exported according to the OpenFOAM file structure. The mesh is saved in a folder named Constant/polyMesh located in the same directory as the *.foam file. The folder contains the following files: points, owner, neighbor, faces, and boundary.
- CGNS
The group information is now included in the CGNS mesh export.
Customer Benefits
- Having mesh exports that preserve groups and folders hierarchy.
BETA features

List of existing BETA capabilities
The functionality below is included in HEXPRESS/Hybrid but requiring additional calibration. The corresponding version is set to Beta. A best practice note can be found in the documentation package.
- Surface to Volume (S2V) mesh generation
- 64 bits indexing mesh export for SPH format
- Viscous layers insertion with the extrusion method
- Viscous layers insertion with the deformation method
- Support of hanging nodes for StarCCM+ export
- Zero radius rotor/stator interface
- Multiblock meshing combining HEXPRESS/Hybrid and S2V
- Holesearcher distributed parallel on LINUX
- CGNS output in Intel MPI version on LINUX
- 64 bits indexing mesh export for Exodus HDF5 format
Customer Benefits
