2D Mesh from Facets dialog box

Mesh Name
Mesh Name	Lets you specify a name for the mesh.
Objects to Mesh
Select Objects	Lets you select one or more polygon bodies or polygon faces to mesh.Note: You can only select unmeshed bodies or faces.
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.
Element Properties
Type	Specifies the type of 2D elements to create, such as linear triangular elements. The types of elements available depend upon the solver you selected when you created the FEM file.To specify an alternative formulation of an Abaqus element, such as a hybrid, click Edit Mesh Associated Data .
Global Element Size
Target Element Size	Specifies the desired 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.
Mesh Parameters
Maximum Growth Rate	Lets you specify the maximum rate at which the element size can change. For example, if you specify a value of 1, the element size remains constant through the mesh. If you specify a value of 2, then the midpoint of an element edge at a distance of 1 away from another element edge can either be double or half the size of the other element edge.
Export Mesh to Solver	Controls whether the software includes the 2D mesh data in your solver input file when you export or solve the model. If you plan to only use this 2D mesh as a seed mesh for a 3D mesh, you should clear this option.
Refinement Settings
Minimum Element Size (% Target Element Size)	Controls the length of the smallest element in the model.
Minimum Element Size (Read-Only)	Displays the length of the shortest element edge in the model based on the Target Element Size and the setting of the Minimum Element Size (% Target Element Size) slider.
Level of Discretization Based on Curvature	Specifies the amount that the software can vary the length of elements in regions of high curvature.
Distance Based Size Variation	Controls the availability of additional options that you can use to vary the density of the elements in the mesh based on the curvature of the facet geometry.
Maximum Distance to Geometry	Available if the Distance Based Size Variation check box is selected.Specifies the maximum deviation allowed from the facet geometry and the resulting mesh. This option primarily affects the appearance of the resulting mesh in regions of curvature.Note: The software does not make the elements in the new mesh smaller than the facets in the input geometry.
Maximum Level of Discretization Based on Curvature	Available if the Distance Based Size Variation check box is selected.Specifies the upper limit on the amount that the software can vary the length of elements in regions of high curvature.
Surface Proximity Based Size Variation	Controls whether the software refines the mesh based on the proximity between surfaces. If you select this check box, the software varies the refinement of the 2D mesh as follows to facilitate the creation of 3D tetrahedral elements in the gaps between the surfaces:The software refines the mesh (decreases the element size) more in areas where the distance between the surfaces is smaller.The software refines the mesh less in areas where the distance between the surfaces is greater.For more information, see Surface and edge proximity settings with 2D Mesh from Facets.
Search Direction	Controls the direction that the software searches relative to the surface normal direction for proximate surfaces.Select Forward to search forward from the surface normal.Select Backward to search backwards from the surface normal.Note: In general, you should select the Backward option when you are meshing a manifold solid body.
Number of 3D Elements Between Surfaces	Specifies the target number of 3D elements to create in gaps between two surfaces. This option allows the software to create elements with a smaller local element size, if appropriate, In general, the software creates 3D element that have the same element edge length as the elements in the 2D surface mesh. In general, as you increase this value, the software may decrease the size of the elements in the 2D surface mesh that are closest to the gap.In some cases, the software may create fewer elements than you request. For example, if you specify a value of 3, and the software can fill the gap with 2 elements, then the software creates 2 elements only.
Edge Proximity Based Size Variation	Controls whether the software refines the mesh based on the proximity between edges within a surface. If you select this check box, the software varies the refinement of the 2D mesh as follows to facilitate the creation of 2D elements in the gaps between the edges:The software increases the mesh refinement (decreases the element size) in areas where the distance between the edges is smaller.The software decreases the mesh refinement in areas where the distance between the surfaces is greater.For more information, see Surface and edge proximity settings with 2D Mesh from Facets.
Number of 2D Elements Between Edges	Specifies the target number of 2D elements to create in gaps between two edges. In general, as you increase this value, the software may decrease the size of the elements in the 2D surface mesh that are closest to the gap. In some cases, the software may create fewer elements than you request. For example, if you specify a value of 3, and the software can fill the gap with 2 elements, then the software creates 2 elements only.
Model Cleanup Options
Small Feature Tolerance	Specifies the percentage of the element size to determine which small features that the software should remove prior to meshing. The software collapses existing short facet edges and merges sliver facet faces with adjacent facet faces.Use this option to define a small feature as a percentage of the total element size. You can specify a percentage of the total element size between zero and 40%. If you specify zero, the software attempts to mesh all features and does not perform any abstraction.The default value is 10.0%. For example, if the element size is 10 mm, the software ignores features, such as facet faces, that are 1 mm or less in size. If you do not want the software to remove small features, specify a value of zero.
Destination Collector
Automatic Creation	Select the Automatic Creation check box to have the software automatically create a new destination collector for the current mesh. If you select this option, the software creates a collector using 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 automatically created mesh collector to specify a physical property table that includes thickness properties.Clear the Automatic Creation check box to choose an existing mesh collector from the Mesh Collector list.
Mesh Collector	Lets you select an existing collector. Click New Collector to use the Mesh Collector dialog box to create additional mesh collectors. For more information, see Mesh collectors.
Show Result	Click Show Result to preview the mesh based on your current selections.
