Meshing

Engineering Solutions offers several meshing algorithms for lines/edges (1D), surfaces (2D) and volumes (3D) which can be accessed via the Mesh menu.

CFD has the following meshing capabilities:

2D Boundary Layer Mesh: Generate 2D meshes with or without boundary layers on planar or non-planar sections defined by sets/groups of edges defining closed loops.
Adaptive Wrapping: Get a clean, water tight shell mesh out of 2D mesh containing several intersecting parts and small gaps which do not need to be modeled.
Automesh: Create meshes or re-mesh existing meshing interactively or automatically on surfaces or groups of elements
BL Thickness: Create a contour plot of the existing distributed thickness values using the Contour panel.
Boolean Operation: Connect intersecting 2D elements. This tool works for triangular as well as quadrilateral elements.
CFD TetraMesh: Generate hybrid grids, containing hexa/penta elements in the boundary layer and tetra elements in the core or fare field.
Check Elements: Verify the basic quality of your elements and to verify the geometric qualities of those elements.
Create Single Component: Opens a dialog to create a single component.
Create CFD Components: Functionality to define the standard CFD collectors. In the dialog, the commonly used collectors names, such as inflow, are pre-selected. Components can be added or removed from the list and a multiplier for each component can be defined. By clicking Create the selected components are created and appear in the Model Browser.
Delete: Delete data from a model database, preview and delete empty collectors and preview and delete unused property collectors, material collectors, or curves.
Detach: Detach elements from the surrounding structure.
Distance: Determine the distance between two nodes/points or the angle between three nodes/points, or to change distances or angles.
Drag: Create a surface and/or mesh by dragging a series of nodes or lines, or to create elements by dragging selected elements.
Edges: Find the free edges in a group of elements, find "T" or discontinuous connections in a group of elements (any edges connected to three or more elements), display duplicate nodes and equivalence duplicate nodes.
Element Cleanup: Perform automatic cleanup of 2D elements based on the element quality criteria from the Quality Index panel or a separate criteria file.
Edit Element: Hand-build, combine, split or modify elements.
Element Offset: Create and modify elements by offsetting from a mesh of plate or shell elements.
Element Types: Select and change existing element types.
Faces: Find the free faces in a group of elements and operates in the same manner as edges, but in 3D.
Features: Calculates features (corners) in the current model and displays them by creating one dimensional plot elements or feature lines.
Fuse: Connect close proximity, overlapping, and intersecting parts.
Hex-Core: Creates a hex-core mesh inside any arbitrary volume defined by a surface mesh consisting of 2D first order elements: tria3 and quad4.
Hidden Line: Create hidden line plots of the displayed structure. Also contains the Clip Boundary Elements tool, which allows you to visually sweep the cutting section for greater viewing clarity.
Hole/Gap Fill: Mesh holes, gaps, and patches.
Intersection/Penetration: Check for penetrations and/or intersections of elements.
Line Drag: Create a two or three dimensional surface and/or mesh or elements by dragging nodes, lines or elements along another line.
Line Mesh: Create a chain of one dimensional elements such as beams along a line.
Linear Solid: Create solid elements between two groups of plate elements.
Mass Calc: Obtain the mass, area and/or volume of a selected group of elements, solids or surfaces.
Mesh Controls: Define one model specific mesh setting, as well as an unlimited number of local mesh settings.
Node Edit: Associate nodes to a point, line, or surface/solid face; move nodes along a surface; place a node at a point on a surface; remap a list of nodes to a line; or project nodes to an imaginary line passing through two nodes.
Nodes: Create nodes using a wide variety of methods.
Normals: Display the normal of an element or surface, adjust the orientation of element normals and reverse the normal of an element or surface.
Planar Surface/Mesh: Create a square, planar surface and/or mesh in a user-specified plane or a surface and/or mesh bounded by planar lines.
Organize: Reorganize your database by copying or moving data (entities) among collectors or includes.
Penetration/Intersection: Check for penetrations and/or intersections of elements.
Periodic Mesh: Generate a grid containing rotational and/or translational symmetric boundaries, for example rotating machinery.
Project: Project data entities to a plane, vector, surface, or line.
Quality Index: Calculates a single value to represent the quality of the displayed shell (2D) model.
Quality Index Calculations: The Quality Index value is a function of twelve criteria with user-defined weight factors.
Reflect: Reflect portions of a model about a plane, changing the selected portion into a mirror image of itself.
Renumber: Renumber entities.
Replace: Allows nodes to be replaced with other nodes.
Rotate: Rotate entities around an axis in space.
Ruled Surface/Mesh: Create surfaces and/or meshes of plate elements from nodes, lines and/or line segments, in any combination.
Scale: Increase or decrease an entity’s dimensions.
Skin Surface/Mesh: Create a skin surface and/or mesh from a set of lines.
Solid Map Mesh: Create a mesh of solid elements in a solid geometric volume.
Solid Mesh: Create meshes in a pentagonal or hexagonal volume defined with edge lines.
Spin: Create a surface and/or mesh or elements by spinning a series of nodes, a line or lines, or a group of elements about a vector to create a circular structure.
Spline Surface/Mesh: Create a shell mesh and/or surface.
Split: Split plate or solid elements.
TetraMesh: Fill an enclosed volume with first or second order tetrahedral elements.
Tetra Mesh Optimization: Improves the quality of a tetra mesh with respect to several element criteria.
Translate: Move entities in a single specified direction.
Wind Tunnel: Creates a hexahedral mesh inside the volume.
