Mesh Menu

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.

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.
Fuse	Connect close proximity, overlapping, and intersecting parts.
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.

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.
