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.

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.
