Mesh from Boundary dialog box

Use the Mesh from Boundary dialog box to create a 2D mesh inside of boundaries, such as holes, or across gaps between faces or component parts.

Method

Lets you select the method to use to define the new 2D mesh.To create a mesh between a source and a target that you define, select Source and Target. Select Source and Target, for example, to create a mesh to span the gap between two faces or two existing meshes. You can select either polygon edges or element edges to define the source and target. The geometry or element edges that you select do not need to form a closed loop. For more information, see Creating a 2D mesh between a source and a target.To create a mesh with a set of element edges that define a closed boundary, select Closed. Select Closed, for example, to create a mesh across a hole or within a bounded set of curves.For more information, see Creating a 2D mesh inside an existing boundary.

Source and Target options

Selection
Source Path	Select the element edges or polygon edges that define where the new 2D mesh should begin.
Target Path	Select the element edges or polygon edges that define where the new 2D mesh should end.
Stacked Smart Selector Methods	Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters to help you select the appropriate element edges or polygon edges.For more information, see Smart Selector Methods dialog box.
Element Properties
Type	Specifies the specific type of element to create.
Edit Mesh Associated Data	Appears when you select an element type that requires the definition of additional properties.Opens the Mesh Associated Data dialog box where you can define solver-specific properties for the elements. The software applies these properties uniformly to all the elements in the mesh. For more information, see Mesh-associated data.
Rail Mesh Parameters
Select Path Rail 1 Rail 2	Lets you select polygon edges or element edges to define the sides (rails) of the new 2D mesh.
Type	Controls how elements are distributed along the sides of the new 2D mesh.Select Uniform to create the same number of elements along each rail. Select Transitioned to specify a different number of elements along each rail.Select Automatic to have the software automatically determine the number of elements to create along each rail.
Number of Layers	Available if Type is set to Uniform.Lets you specify the number of rows of elements to create.
Show Rails	Controls whether the software uses temporary graphics to display the location of the rails.
Number of Elements along Rail 1****Number of Elements along Rail 2	Available if Type is set to Transitioned.Lets you specify the number of elements to create along each side of the new mesh.
Destination Collector/Mesh
Automatic Creation	Controls the creation of a mesh collector.Select the Automatic Creation check box to automatically create a new destination collector for the 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.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. See Mesh collectors for more information.
Automatic	Automatically updates the previewed mesh when you specify or change a value.
Show Result	Previews the mesh based upon your current selections.

Closed options

Selection
Select Element Edge Loops****Select Object	Lets you select a set of connected element edges that define a closed loop.Tip: Use the Element Edges or Mesh selection filter with the Hole Element Edges smart selection method to efficiently select holes that meet specific size criteria. Use options in the Smart Selector Options dialog box to specify criteria to control the types of holes that the software selects.
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.
Boundary List
Boundary ID	Lists each loop of element edges in ascending order of the number of nodes in the loop. When you click OK or Apply, the software fills all the loops in the list with elements.
Number of Nodes	Lists the number of nodes in each loop of selected element edges.
Remove Boundary From List	Removes a selected loop from the list.
Element Properties
Type	Specifies the specific type of element to create.
Edit Mesh Associated Data	Appears when you select an element type that requires the definition of additional properties.Opens the Mesh Associated Data dialog box where you can define solver-specific properties for the elements. The software applies these properties uniformly to all the elements in the mesh. For more information, see Mesh-associated data.
Destination Collector/Mesh
Automatic Creation	Controls the creation of a mesh collector.Select the Automatic Creation check box to automatically create a new destination collector for the 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.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. See Mesh collectors for more information.
Show Result	Previews the mesh based upon your current selections.
