2D Mapped Mesh dialog box

Types
Element Type	Specifies the type of 2D element to create, such as linear triangle or linear quadrilateral elements. To specify an alternative formulation of an Abaqus element, such as a hybrid, click Edit Mesh Associated Data .
Destination Collector
Automatic Creation	Controls whether the software creates a new mesh collector for the mapped mesh. When Automatic Creation is selected, creates a new destination collector. The automatic mesh collector uses the default physical properties and inherits the material properties of the idealized part.Note: If you did not use a midsurface to generate the 2D mesh, you must edit the mesh collector to specify a physical property table that includes thickness properties.When the Automatic Creation check box is cleared, lets you choose an existing mesh collector from the Mesh Collector list. Click New Collector to use the Mesh Collector dialog box to create additional mesh collectors.
Selection
Select Objects	Lets you select the polygon bodies, faces, or existing meshes to mesh.
Stacked Smart Selector Methods	Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
Meshing Parameters
Element Size	Lets you specify a target element size for the mesh.To specify the element size as a function of frequency, click the DesignLogic list and select Function to use the SizeForAcoustics function. For more information, see Element size for acoustic analysis.
Automatic Element Size	Examines the selected geometry and calculates an estimated element size. The Overall Element Size field updates to show this element size.Note: The element size calculated by Auto Element Size is an estimate based upon certain characteristics of the currently selected geometry. You should always carefully evaluate your model and use good engineering judgment when determining the element size, regardless of whether you accept the software’s estimate or specify a different size. This evaluation should consider both the unique features of your model's geometry and the requirements of your analysis.See Understanding the Automatic Element Size calculation.
Export Mesh to Solver	Controls whether the software exports the mesh to the specified solver. If you plan to use the 2D mesh as a seed mesh for a 3D mesh, you may want to clear this option.
Preview and Modify Mesh Constraints
Show Result	Displays temporary graphics that indicate the approximate nodal density along the boundaries of the selected faces. Show Result can help you determine whether the element size you specified is appropriate.
Define Corners
Select face corner	If the selected geometry contains more than four logical sides or corners, lets you select the three or four corners to use to define the composite sides.
Edge Density
Number of Elements	Once you select an edge in the graphics window, lets you specify the number of elements to create along that edge.
Mesh Options
Merge Edges	Controls whether the software removes unnecessary vertices and then merges the associated edges. This prevents the software from generating a node at that location during meshing. The software removes a vertex if it connects two or fewer edges and if the angle between those edges is less than or equal to the threshold value you specify in the Vertex Angle box.
Vertex Angle	Lets you specify the threshold value the software uses for removing vertices. The Vertex Angle is the angle between two separate edges that are joined at a vertex along the boundary of a face.
Edge Match Tolerance	If you are meshing multiple sheet bodies, controls whether the software matches the nodes on the edges of the different sheet bodies to generate a continuous mesh. If you want the software to generate a continuous mesh across multiple sheet bodies, the edges and ends of edges of the different sheet bodies must be within the specified Edge Match tolerance.
Quad Only on 3 Sided Faces	Controls whether the software creates a mesh that does not contain any triangular elements on a three-sided face.If you select Quad Only on 3 Sided Faces, the software tries to create a mesh that contains only quadrilateral elements for faces that have three sides. With this option, if the software is unable to maintain parity (an even number of nodes along the boundary of a face) due to constraints from existing meshes on surrounding faces, it creates triangular elements at a selected corner.If you clear the Quad Only on 3 Sided Faces check box, the mapped mesh of quadrilateral elements degenerates into triangular elements in a selected corner.For more information, see Quadrilateral only meshing.
Store Free Mesh If Mapped Mesh Fails	If the software is unable to generate a mapped mesh on a selected face, it automatically generates a free mesh on that face instead. This option controls whether the software retains that free mesh.If you select Store Free Mesh if Mapped Mesh Fails, the software keeps the free mesh.If you clear the Store Free Mesh if Mapped Mesh Fails check box, the software does not keep the free mesh. You may want to clear this check box in situations where you want to more easily see any faces on which the software failed to generate a mapped mesh.
Edge Mapping	Projects vertices along the edges of a face to the opposite edge. This forces the creation of nodes at the projected locations on the opposite edge and can result in a more uniform mesh. For more information, see Projecting vertex locations in mapped meshes.
Flip Diagonals	Reverses the direction of the elements' diagonals (hypotenuse). For more information, see Controlling element diagonals.
Attempt Multi-Block Decomposition	Uses the multi-block decomposition technique to try to generate a more structured mesh. Select this option when a face has more than five edges or when the software is not otherwise able to generate a mapped mesh.With this option, the software internally subdivides faces with a number of near 90° corners into a cluster of convex regions. The software then generates meshes on each convex region. In general, the resulting meshes are more structured in nature.For more information, see Multi-block decomposition in meshing.
