A 


2D frontal mesher, providing linear triangle elements and linear quadrangle elements. This mesher allows the geometry simplification by creating domains. 

B 


A rounded ridge of uniform width, straight or curved. Beads are used to stiffen sheet metal surfaces. 

bead mesh method 
Mesh method for beads, using
quadrangle and triangle elements. 

C 


collapse 
Suppression of an edge on a geometry by merging its two vertices. As a result, a vertex replaces the edge. 

constraint 
In the Advanced Meshing Tools workbench, a constraint on a geometry means that the mesher will take into account the constrained points (or the constrained edges) to build the mesh. As a result, a constraint applied to a vertex creates a node on this vertex, and a constraint applied to an edge aligns the element edges on this edge. 

constraint sag 
This global parameter helps creating constraints on a geometry, but does not guarantee that the whole mesh respects the sag value. For a given mesh size, a low constraint sag generates numerous constraints, and a high constraint sag generates few constraints. The constraint sag must value between 5% and 20% of the mesh size. This global parameter is only available with the advanced surface mesher. 

crack 
A geometry defect that occurs when two adjacent faces, near
the free edges, are not geometrically linked.


cut 
Creation of a vertex on an edge. As a result, the edge is cut in two edges. 

D 


A sub part on a surface. You can specify a domain, to remesh, remove, or lock the mesh on this area. 

duplicate element 
Elements that share exactly the same nodes. 

E 


On a geometry: salient angle of the surface. 

F 


Edge of an element, positioned on the border of the mesh. 

frontal mesh method 
Nonstructured free mesh method, usable on all domains, using triangle and quadrangle elements. In the Advanced Meshing Tools workbench, the frontal method is a 2D mesh method.


G 


global size 
The target size for element edges. 

I 


interference 
A given distance (or clearance) beyond which the elements generated are positioned. This lets you take into account the real width of the geometry. 

intersection 
A standard geometrical intersection. 

imposed elements 
Imposed elements on a mesh enforce the mesh to take into account these elements. 

M 


mapped free mesh method 
Semistructured mesh method for quadrangular geometry only,
using quadrangle elements. 

mapped mesh method 
Structured mesh method for quadrangular geometry only, using quadrangle or triangle elements.


mapping mesh method 
This mesh method copies and pastes a mesh from a geometry
to a similar geometry. 

Preprocessor for computational programs creating a virtual grid on the geometry. 

The minimum size of an edge of an element. When the Merge During Simplification option is activated, the mesher does not generate elements with edges shorter than the minimum size. This option is available with the advanced surface mesher. 

maximal gap 
In a connection context, this is the maximal distance between a geometric point and the mesh elements of each geometry to connect. 

O 


octree mesh method 
Free mesh method, generating triangle elements for a 2D mesh, and tetrahedron elements for a 3D mesh. 

offset 
Small displacement (of a mesh or geometry). 

P 


part 
A 2D or a 3D entity obtained by combining different
features in the Part Design workbench. 

projection mesh method 
This mesh method copies and pastes a mesh from a geometry
to an identical geometry. 

Q 


quality analysis 
You can control and visualize the quality of a mesh by selecting or modifying the quality criteria. 

S 


sag 
The distance between the mesh elements and the geometry so
that mesh refining is optimum in curvetype geometry. 

smart surface mesh 
Feature created in the specification tree when using the advanced surface mesher. 

During simplification, edges under the minimum size are merged. This reduces the number of constraints. On a simplified geometry, the mesh always respects the minimum size of elements. 

split 
Creation of a constrained edge on a domain. 

strip 
In this thin area of the geometry, the mesh elements are created face to face, for an improved mesh. 

structure design beam 
Beam created in the Structure Design workbench. 

T 


tetrahedron filler 
Mesher filling a 2D mesh with tetrahedron elements to create a 3D mesh. 

Maximum distance. 

V 


Point at the extremity of an edge, on a mesh or on a geometry.
