3.2.1 Geometric Entities(几何实体)

    The geometric entities in the Geometric Entities Panel are the Volumes, Boundaries, Interfaces, CAD Surfaces, Derived Surfaces, Points, Streamline, Particles and Built Meshes.
    几何实体面板中的几何实体包括体积、边界、界面、CAD 表面、派生表面、点、流线、粒子和构建网格。

Figure 3.11 - Geometric entities

CAD Surfaces(CAD 表面)

    Surfaces is a term used in Simerics-MP/Simerics-MP+ to refer to a collection of points and lines (triangulation) that define a surface. These are used to define the geometry for a simulation and are used to generate the numerical mesh. Geometry refers to surfaces that define two-dimensional or three-dimensional objects. Once geometry is imported into Simerics-MP/Simerics-MP+, the surfaces defining a geometry are listed under CAD Surfaces.

    表面是 Simerics-MP/Simerics-MP+ 中使用的术语，指的是定义表面的点和线（三角剖分）的集合。它们用于定义模拟的几何形状，并用于生成数值网格。几何形状是指定义二维或三维对象的表面。将几何形状导入 Simerics-MP/Simerics-MP+ 后，定义几何形状的表面将列在 CAD 表面下。

• CAD Surfaces are different from Boundaries or Interfaces in that they are not connected to the mesh and are not part of the solution. They are typically used to define the shape of a volume during mesh creation.

  CAD 表面不同于边界或界面，因为它们不连接到网格，也不是解决方案的一部分。它们通常用于在网格创建期间定义体积的形状。
  

• CAD Surfaces are typically in .STL format, but can be in other formats as well, including Nastran Grid Format,** Gambit Neutral Format** or ANSYS CDB file.

  CAD 表面通常为 .STL 格式，但也可以采用其他格式，包括 Nastran 网格格式、Gambit 中性格式或 ANSYS CDB 文件。

Volumes(体积)

    Mesh (or Grid) in Simerics-MP refers to a collection of points and lines that define the Volumes (2D or 3D) and Boundaries used by the numerical solver. The mesh in Simerics-MP/Simerics-MP+, is unstructured and is generated from CAD Surfaces. The Grid is both on the boundaries of a volume and on the interior. The Grid is stored in a Simerics proprietary file format with the file extension *.sgrd.

    Simerics-MP 中的网格（或格子）是指定义数值解算器使用的体积（2D 或 3D）和边界的点和线的集合。Simerics-MP/Simerics-MP+ 中的网格是非结构化的，由 CAD 表面生成。网格既位于体积的边界上，也位于内部。网格以 Simerics 专有文件格式存储，文件扩展名为 *.sgrd。

Volumes are created:

• During mesh generation, if a closed (“water-tight”) collection of CAD Surfaces is selected.

体积创建于：

• 在网格生成期间，如果选择了封闭的（“水密的”）CAD 表面集合。

Boundaries(边界)

    A boundary is a collection of mesh cell faces that defines an external surface boundary of a model. “External” does not necessarily mean that the boundary is at the exterior of the model, but rather that is not numerically connected to any mesh cells on the other side. Boundary information is used directly in the numerical simulation.

    Boundaries are created/introduced by one of two ways:

• During mesh generation, if they correspond to an external boundary in the CAD Surfaces.

• Interfaces between two Volumes are automatically converted to Boundaries if one of the Volumes is deleted.

    边界是定义模型外部表面边界的网格单元面的集合。“外部”并不一定意味着边界位于模型的外部，而是在数值上与另一侧的任何网格单元没有连接。边界信息直接用于数值模拟。

    边界通过以下两种方式之一创建/引入：

• 在网格生成期间，如果它们对应于 CAD 表面中的外部边界。

• 如果删除其中一个体积，两个体积之间的界面将自动转换为边界。

Interface(界面)

    This is an internal boundary within a model. It can reside within a volume or connect two separate volumes. It connects the mesh cells on either side of the interface. For more information, refer Interface Creation.(4.3 Interface Creation)

    这是模型内的内部边界。它可以位于一个体积内，也可以连接两个独立的体积。它连接界面两侧的网格单元。有关更多信息，请参阅界面创建。(4.3 界面创建)

Mismatched Grid Interface(MGI)(不匹配网格接口 (MGI))

    Mismatched Grid Interfaces (MGI) is an algorithm for connecting boundaries. For more information, refer Interface Creation.(4.3 Interface Creation)

    不匹配网格接口 (MGI) 是一种连接边界的算法。有关更多信息，请参阅界面创建。(4.3 界面创建)

Built Meshes（构建网格）

    When meshes are created using either the General Mesher（4.2.2 General Mesher） or the Template Mesh/Surface（3.4 Mesh Panel）, a new entity appears in the Geometric Entities Panel under Built Meshes.

    They provide a list of the meshes generated and contains the relevant information pertaining to the created mesh construction.

• The CAD Surfaces used to make a water-tight, completely closed volume.

• The mesh settings used when the mesh was generated (cell size, cell size on particular surfaces, etc.).

• This also gives the choice to regenerate the mesh (Finer or Coarser, clustering in a particular area, etc.).

    使用通用网格生成器（4.2.2 通用网格划分器）或模板网格/表面（3.4 网格面板）创建网格时，几何实体面板中的“构建网格”下会出现一个新实体。

    它们提供生成的网格列表，并包含与创建的网格构造相关的信息。

• 用于制作密封、完全封闭体积的 CAD 表面。

• 生成网格时使用的网格设置（单元大小、特定表面上的单元大小等）。

• 这也提供了重新生成网格的选择（更细或更粗、在特定区域中聚类等）。

Derived Surfaces(派生曲面)

    These are geometric entities created explicitly, typically for post processing(12 - Post-Processing).

• Two derived entities, Iso-surfaces （3.2.2）and Sections（12.1 Cross-Sections and Monitoring Points）, can be created using Create an Isosurface and Create a Cross-Section, respectively.

• Once created, they are listed in the Geometric Entities Panel under the heading Derived Surfaces.

• For more information, click Create an Isosurface（3.2.2） and Create a Cross-Section（12.1 Cross-Sections and Monitoring Points）.

    这些是明确创建的几何实体，通常用于后期处理(12-后处理)。

• 可以分别使用“创建等值面”（3.2.2）和“创建横截面”12.1 断面及监测点创建两个派生实体，即等值面和横截面。

• 创建后，它们将在“几何实体”面板的“派生曲面”标题下列出。

• 有关更多信息，请单击“创建等值面”（3.2.2）和“创建横截面”12.1 断面及监测点。

Streamline（流线）

    Streamline module is used to create Streamline in the flow. For information on the creation and display of Streamline, see Streamline （12.4 Display Streamline）module.

    Streamline （流线）模块用于在流程中创建 Streamline（流线）。有关 Streamline（流线） 的创建和显示的信息，请参阅 Streamline（流线）（12.4 显示流线）模块。

Particles（粒子）

    Particle module is used to create particles. For information on the creation and display of particles, see Particle（12.5 Particles） module.

    粒子模块用于创建粒子。有关粒子的创建和显示的信息，请参阅粒子模块（12.5粒子）。

注意

    The Boundaries, Interfaces, Volumes are listed as an independent category or as a sub-category, subordinate to their respective Volumes using the Group Entities by Volumes/Types  icon.

    边界、接口、体积被列为独立类别或子类别，使用按体积/类型图标对实体进行分组，从属于它们各自的体积。

3.2.2 Geometric Functions（几何函数）

    The geometric functions in the** Geometric Entities Panel** allow to create Cross Section, Points, Isosurface, Connect Boundaries via MGI, Delete selected entity etc.

    几何实体面板中的几何函数允许创建横截面、点、等值面、通过 MGI 连接边界、删除选定实体等。

Figure 3.12 - Geometric functions

Group Entities by Volume/Types/按数量/类型对实体进行分组/

    This switches between the listing of geometric entities: either as independent categories based on type or as a hierarchy based on volumes. See Figure 3.13 and Figure 3.14.

    这会在几何实体列表之间切换：要么作为基于类型的独立类别，要么作为基于体积的层次结构。参见图 3.13 和图 3.14。

Figure 3.13 - Group entities by volumes

Figure 3.14 - Group entities by types

Create a Cross-Section创建横截面

    This is used to create cross-sections(12.1 Cross-Sections and Monitoring Points). The orientation of the cross-section is set in the Properties Panel corresponding to an ordinate direction (Plane X, Plane Y, or Plane Z) or an angle (Arbitrary Plane).

    这用于创建横截面(12.1 断面及监测点)。横截面的方向在属性面板中设置，对应于纵坐标方向（平面 X、平面 Y 或平面 Z）或角度（任意平面）。

Create a Isosurface创建等值面

    This is used to create iso-surfaces(12.1 Cross-Sections and Monitoring Points). The shape of a given Iso-surface depends on the Isosurface Variable, Display Option and Value as set in the** Properties Panel**.

    这用于创建等值面(12.1 断面及监测点)。给定等值面的形状取决于属性面板中设置的等值面变量、显示选项和值。

Create a Monitoring Point创建监控点

    A point is a specified coordinate within a model, used to record Primary Variables, Physical Properties and Derived Variables (5.2.4 Output Variables)data at that location. For more information, go to Points(12.1-Monitoring Points).

    点是模型中指定的坐标，用于记录该位置的主变量、物理属性和派生变量（5.2.4 输出变量）数据。有关更多信息，请参阅点（12.1-监测点）。

Connect Selected Boundaries via MGI通过 MGI 连接选定边界

    Boundaries are connected using Connect Selected Boundaries via MGI option in the Geometric Entities Panel. MGI is an algorithm for connecting boundaries. For more information, go to Connect Selected Boundaries via MGI(4.3MGI (Mismatched Grid Interface)).

    使用几何实体面板中的通过 MGI 连接选定边界选项连接边界。MGI 是一种连接边界的算法。有关更多信息，请参阅通过 MGI 连接选定边界(4.3MGI（不匹配网格接口）)。

Delete Selected Geometric Entity(删除选定的几何实体)

• This permanently removes a selected item.

• There is no “undo” for deletion.

• If an entity is associated with another entity, the sub-ordinate entity must be deleted first. For example, MGIs connected to a volume must be deleted prior to deleting the Volume.

• 这将永久删除选定的项目。

• 删除后无法“撤消”。

• 如果一个实体与另一个实体相关联，则必须先删除下属实体。例如，必须先删除连接到卷的 MGI，然后再删除卷。

Deselect Highlighted Entities取消选择突出显示的实体

    This turns off the display of the selected entity and reverts to the display of all entities.
    这将关闭所选实体的显示并恢复所有实体的显示。

Display Highlighted Geometric Entities显示高亮显示的几何实体

    This toggles between the display of the selected entities versus display of all entities.
    这会在显示选定实体和显示所有实体之间切换。
