Surface Wrap Recipe dialog box

Surface Wrap Boundaries
Bodies/Meshes/Element Faces	Lets you select the following entities in the same surface wrap recipe to define the surface wrap boundaries:Polygon bodies2D or 3D imported meshes2D shell elements or 3D element free faces of imported meshesSelection recipes that contain the geometry or imported meshesThe elements and meshes must not be associated to a polygon body.Note: Even though the software supports selecting individual 2D elements, and faces of 3D elements, it is much more efficient to select 2D or 3D meshes instead.
Surface Wrap Interior/Exterior
Surface wrap definition method list	Specifies the surface wrap definition methods.Face and Normal Vector Toward the InteriorLets you specify a face that is on the surface wrap boundary and a normal vector to that face that points toward the surface wrap interior. You specify the face using Face and the vector using Specify Vector . You can reverse the direction of the vector using Reverse Direction .Interior PointLets you select a point that is in the surface wrap interior. The software starts the wrapping process from this point. This point must not touch any of the surface wrap boundaries. You specify the point using Point .Wrap around the ExteriorCreates a surface wrap body around the exterior of the domain.Interior Points from CavitiesLets you select one or more automatically detected cavities to drive the surface wrapping process when you click Select Cavities. The software displays the number of selected cavities. For more information, see Select Cavities dialog box.
Feature Edge Detection
Detect Feature Edges	Available when the Bodies/Meshes/Element Faces selection includes meshes or element faces.Activates the feature edge detection on the selected entities. The software uses feature edges that are part of a closed loop to generate surface wrap bodies and meshes that conform better to the surface wrap boundaries along the detected edges. You must set the minimum angle between the normals of two adjacent elements in the Element Face Feature Angle box to determine whether their shared edge is a feature edge. You can choose an angle between 30° and 150°. You can use Preview Edges to display the detected edges in the graphic window. When you clear the Detect Feature Edges check box, the software assumes the connected element faces are on the same polygon face.
Surface Wrap Resolution
Global Resolution	Sets the global resolution for the octree Cartesian triangular mesh that the wrapping algorithm uses to create the surface wrap body.
Auto Calculate	Computes the global resolution automatically.
Use Automatic Refinement	Activates the automatic refinement on the surface wrap selection. The software determines the optimal resolution required to correctly capture the input boundaries. You must specify a maximum subdivision value from the Max Subdivision list. You can choose between 1 and 8 (Very Fine).The software computes and displays the minimum resolution value in the Minimum Resolution box as follows: R/2x, where R is the global resolution value and x is the maximum subdivision value. For each problematic section of your model, it uses an appropriate local resolution value that is between the minimum resolution and the global resolution.
Smoothing and Snapping Options
Smoothing Level	Controls the precision of the surface wrapping. To disable smoothing and snapping, set this value to 0.
Snap to Source Boundaries	Available when Smoothing Level is greater than 0.Projects the surface wrap body edges onto the input boundaries.
Output Options
Output options list	Specifies the generated entities.Surface Wrap BodyGenerates only the surface wrap body.Surface Wrap Body and Associated 2D MeshGenerates a surface wrap body and a surface wrap shell mesh fully associated to the faces of the surface wrap body. 2D MeshGenerates a 2D mesh not associated to any polygon body.Note: The default element size of the generated mesh depends on the wrapping resolution and wrapping constraints.
Export Mesh to Solver	Available when the output option is set to Surface Wrap Body and Associated 2D Mesh or 2D Mesh.Controls whether the software includes the 2D mesh data in your solver input file.
Specify Element Size	Available when the output option is set to Surface Wrap Body and Associated 2D Mesh or 2D Mesh.Specifies that you want to define the element size of the associated 2D mesh. You specify the element size of the 2D mesh in the Element Size box.
Destination Collector	Available when the output option is set to Surface Wrap Body and Associated 2D Mesh or 2D Mesh.Lets you define the destination collector for the created 2D mesh.Automatic CreationCreates a collector automatically 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 CollectorAvailable when the Automatic Creation check box is cleared.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.
Meshing Options
Appears when the output option is set to Surface Wrap Body and Associated 2D Mesh or 2D Mesh.
Type	Specifies the type of 2D element to create, such as linear or parabolic triangular or quadrilateral elements.
Specify Element Size	Lets you specify the target element size for the selected faces that you set in the Element Size box.
Surface Curvature Based Size Variation	Available when Specify Element Size is selected.Lets you vary the size of your elements in regions of higher surface curvature. This allows you to create more, smaller elements in areas of higher curvature. For example:If you set 0, the software uses the overall element length throughout the model regardless of the curvature.If you set 50%, the software varies the element length between 50% and 100% of the overall element size based on the surface curvature.If you set 100%, the software varies the element length between 1% and 100% of the overall element size.The software transitions the element size from a local length to a global length when you set the Surface Curvature Based Size Variation slider to a value greater than 10%. The curvature of the surfaces determines when the software transitions the element size.
Surface Curvature Threshold (Read- Only)	Displays the smallest element size based on the overall Element Size and the setting of the Surface Curvature Based Size Variation slider. This value decreases, as the value of surface curvature based variation increases.
