Meshing Preferences dialog box

Option	Description
Context	Lets you display options, settings, and values that are appropriate in the context of a given analysis type.Select General Analysis to display options, settings, and values that are appropriate for all analysis types.Select Crash Analysis to display options, settings, and values that are optimized for crash analysis. With this option, the software optimizes the available settings and algorithms to generate a mesh that meets the quality requirements and characteristics required for crash analysis. For more information, see Meshing for crash analysis.
Snap Tolerance	Lets you specify a value for a geometric tolerance that is used in several meshing and geometry abstraction functions. Snap Tolerance is primarily used by the calculations of the Auto Element Size tool. Specifically, the software uses 1.5*( the specified Snap Tolerance) as the lower limit for the estimated element size.See Understanding the Automatic Element Size calculation for more information.The Snap Tolerance is also used in several other pre-processing commands.See Understanding the Snap Tolerance value for more information.
Tiny Edge Color	Sets the highlight color for edges for the Show Tiny Edges command. Tiny edges are edges that are smaller than the Small Feature Tolerance/Minimum Element Length value in the meshing dialog boxes.See Show Tiny Edges for more information.To highlight the tiny edges in your model, right-click an existing mesh in the Simulation Navigator and select Show Tiny Edges from the menu.
Project Nodes to CAD Geometry	During 2D meshing, controls whether the software projects nodes to the polygon geometry or the underlying CAD geometry.Note: If you select this option, you must have the idealized part loaded before you can create a mesh.Do not select this option if you plan to later select the Move Nodes Off Geometry option in the 2D Mesh dialog box.See Controlling the proximity of nodes to the CAD Geometry for more information.
Projection Tolerance	If you select the Project Nodes to CAD Geometry option, specifies the tolerance that the software uses to evaluate the proximity of a node to a CAD edge or faceIf the distance between a node and the CAD geometry is less than the Projection Tolerance, the software does not move the node.If the distance between a node and the CAD geometry is greater than the Projection Tolerance, the software moves the node along a vector so that it lies within the tolerance.
Set Maximum Number of Elements Based on Curvature	Lets you specify the maximum number of elements to create along a curve. Use this option to prevent the software from generating overly large number of element edges along a curve while ensuring that there is adequate discretization to capture essential details.
Maximum Number of Elements per 90 Degrees	Available if you select the Set Maximum Number of Elements Based on Curvature check box.Specify the maximum number of elements to create along a 90° arc.
Set Minimum Number of Elements on an Arc	Lets you specify the minimum number of elements to create along a 90° arc. Use this option to ensure that the software adequately discretizes the arc's curvature.
Minimum Number of Elements per 90 Degrees	Available if you select the Set Minimum Number of Elements on an Arc check box.Specify the minimum number of elements to create along a 90° arc.
