Crash has the following meshing capabilities:  

 

Acoustic Cavity Mesh

Create a fluid volume mesh for the open-air volumes of an enclosed compartment, such as the passenger compartment of a vehicle.

Automesh

Create meshes or re-mesh existing meshing interactively or automatically on surfaces or groups of elements.

Bars

Create, review or update bar2 or bar3 elements.

Bead

Creates bead on the surface mesh along a line defined by two nodes.

Boolean Operation

Connect intersecting 2D elements. This tool works for triangular as well as quadrilateral elements.

Box Trim

Trims the model based on box with option to constraint the model’s trimmed edges.

Card Editor

Select the entities that are viewed in the card image subpanel.

Check Elems

Verify the basic quality of your elements and to verify the geometric qualities of those elements.

Comparison Tool

Perform a model-based CAD-CAD, CAD-FE or FE-FE comparison between two models, or two selections of entities. You can also use this tool to find and report on geometrical/shape differences.    

Config Edit

Make changes to the configuration of existing elements.

Delete

Delete data from a model database, preview and delete empty collectors and preview and delete unused property collectors, material collectors, or curves.

Dependency

Find nodes that have their degrees of freedom removed by a constraint or MPC (multiple point constraint) more than once.

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.

Edit Element

Hand-build, combine, split or modify elements.

Element Cleanup

Perform automatic cleanup of 2D elements based on the element quality criteria from the Quality Index panel or a separate criteria file.

Element Offset

Create and modify elements by offsetting from a mesh of plate or shell elements.

Elem Type

Select the type of element to create and also allows you to change existing element types.

EM Lattice Mesh

Generate an axis-parallel mesh for 2D and 1D geometry input.

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.

Fill Hole

Fills a hold on the surface mesh based on your selection or through hold recognition and filters based on the hole radius.

Gaps

Create gap elements.

Hole Detection

Enables you to locate and define many, or all, holes in a model and add those holes as geometry to a new component or the current one.

Hole/Gap Fill

Mesh holes, gaps, and patches.

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 1D

Create one dimensional elements.

Linear 3D

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

Masses

Create mass elements.

Mesh Controls

Define one model specific mesh setting, as well as an unlimited number of local mesh settings.

Midmesh Thickness

Calculate the thickness of a mid-mesh from the solid geometry.

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.

Order Change

Change element order.

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.

Permute

Switch coordinates of model entities in the global coordinate system.

Position

Specify a new position for model entities.

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.

Quality Report

Creates an HTML mesh quality report.

Quick Edit

Many tools for rapid editing of model geometry.

RBE3

Create, review and update RBE3 elements.

Refine by Pattern

Create a regular orthogonal mesh.

Reflect

Reflect portions of a model about a plane, changing the selected portion into a mirror image of itself.

Renumber

Renumber entities.

Rigids

Create rigid or rigid link elements.

Rods

Create rod elements.

Rotate

Rotate entities around an axis in space.

Ruled

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.

Shrink Wrap Mesh

Generate an enclosed volume or solid mesh and is typically used to approximate and simplify an existing mode.

Skin

Create a skin surface and/or mesh from a set of lines.

Smooth

Improve element quality in a surface-based mesh or a mesh of solid elements using one or more algorithms that adjust node positions to moderate sharp variations in size or quality in adjacent elements.

Solid Map Mesh

Create a mesh of solid elements in a solid geometric volume.

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

Create a shell mesh and/or surface.

Split

Split plate or solid elements.

Springs

Create spring elements.

System

Create rectangular, cylindrical and spherical coordinate systems.

TetraMesh

Fill an enclosed volume with first or second order tetrahedral elements.

TetraMesh Process

Create tetra-meshes efficiently and effectively.

Translate

Move entities in a single specified direction.

Trim Hole

Creates a hole on surface mesh with options to customize the mesh around the hole and create spiders for connections.

Voxel Mesh

Fills an enclose volume with voxels (hexas) of a predefined size. This type of mesh is only useful in topology optimization. It does not give meaningful results in a stress analysis.

Washer

Creates washer around free edges in the surface geometry.
