FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry
is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.
1D mesh that allows accurate testing of connectors, such as bolts, and similar rod-like or bar-like objects that can
be modeled as a simple line for FEA purposes.
Use the General 2D Mesh: Biasing tool to apply linear, exponential, or bellcurve biasing to individual edges of a surface, and edit the elements size
distribution.
Use the CFD 2D Mesh tool to generate hybrid grids containing hexa/penta/tetra elements in the boundary layer and tetra elements in the
core or fare field.
Automatically generate a mesh at the midplane location, directly from the input geometry (components, elements, solids
or surfaces), without first creating a midsurface.
The Rebuild tool streamlines the process of remeshing existing meshes to generate a new mesh with good quality and flow. The rebuild
mesh functionality utilizes the same parameter and criteria files used by BatchMesher to define the quality criteria and relevant mesh parameters. This algorithm saves significant time over the traditional
automesh and quality correction approach.
Adaptive wrap meshing is a useful utility to 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.
Shrink wrap meshing is a method to create a simplified mesh of a complex model when high-precision models are not
necessary, as is the case for powertrain components during crash analysis.
Bulkheads are design enablers that provide localized performance benefits for multiple design attributes such as NVH,
Safety, and so on. When their position and thickness are precisely designed, bulkheads can reduce mass and increase
performance as they eliminate up-gauging of entire part(s). Typically, bulkheads are welded on one side and bonded
with a structural adhesive on the other side and can be incorporated even during the late stages of the product
design cycle.
Doublers are design enablers that provide localized performance benefits for multiple design attributes such as NVH,
Safety, and so on. When their position and thickness are precisely designed, doublers can reduce mass and increase
performance as they eliminate up-gauging of entire part(s). Typically, doublers are typically welded on one side and
bonded with structural adhesive on the other side and can be incorporated even during the late stages of the product
design cycle.
Volume mesh or "solid meshing" uses three-dimensional elements to represent fully 3D objects, such as solid parts
or sheets of material that have enough thickness and surface variety that solid meshing makes more sense than 2D shell
meshing.
Use the General 2D Mesh: Create
tool to create a surface mesh and remesh elements.
A surface mesh or "shell mesh" represents model parts that are relatively
two-dimensional, such as sheet metal or a hollow plastic cowl or case. Surface
meshes are placed on the outer faces of solid objects, and are used as a baseline
mapping point when creating more complex 3D meshes (the quality of a 3D mesh largely
depends on the quality of the 2D mesh from which it is generated).
General 2D Mesh should be
the default surface mesh tool selected. To view a drop-down menu of available
surface mesh methods, click the arrow on the right side of the tool.
From the Mesh ribbon, click the General 2D Mesh tool.
By default, the Create should be selected from
the secondary ribbon.
Optional: On the guide bar, click
to define surface mesh options.
Select surfaces, solids, or elements to mesh.
Tip: To select only unmeshed surfaces, right-click on a surface and
choose Select Unmeshed Surfaces from the context
menu.
Enter an average element size in the microdialog.
Click Mesh on the guide bar or the microdialog.
A mapped, all quad, mesh is generated. If a surface is determined to not
be mappable, that surface is not meshed.
Any failed surfaces remain selected
when returning to the Create tool, or when Mesh
mode is set to Automatic.
Tip: When using the other surface mesh tools, you can always go back to the
Create tool to add and/or remove surfaces from the
meshing area.
