Mesh Deformation Reference

You specify the mesh deformation solver properties and define mesh deformation boundary conditions by setting Morpher Specification and Morpher Thin Factor.

Mesh Deformation Properties

Specifies solver settings for mesh deformation solver.

Verbosity
Provides more information on the mesh deformation operation to the Output window.
  • None: No additional output.
  • Low: Additional information about deformation point positions.
  • High: Additional information about numerical parameters of mesh deformation morphing operation.
Morpher Tolerance
Non-dimensional parameter that is used to specify acceptable accuracy in morphing. This parameter is multiplied by the longest edge length of the bounding box enclosing the morphing region.
Maximum Recommended Design Points
The recommended upper limit for the number of fixed and displacement design points. The default is 1000. A recommended maximum number of design points is specified, because an excessive high number of design points can become expensive computationally. When the specified limit is exceeded, a warning is issued before the execution of a Compute Mesh Sensitivity and Deform Mesh operation if auto-thinning is disabled. For more information, see Computing the Shape Sensitivity and Executing Deform Mesh.
Enable Automatic Thinning
Activated by default. Automatically thins out fixed and displacement boundary vertices for mesh deformation morphing.

Morpher Specification Priority

Defines how the vertices at the boundary are morphed through employing design points. For more details on the morpher boundary methods, see Morpher Boundary Conditions Reference.

Fixed
The boundary remains fixed. The points on this boundary are treated as design points with zero displacement. Selecting this option adds the Morpher: Thin Factor node to the Physics Values node of the boundary.
Floating
Vertices on this boundary move according to the displacement interpolation of the design points.
Displacement

Vertices on this boundary are collectively viewed as design points. They move according to the computed displacement of the mesh deformation solver. Selecting this option adds the Morpher: Thin Factor node to the Physics Values node of the boundary.

Morpher Thin Factor Priority

Specify a value less than 1 for the Vertex Thin Factor to override auto-thinning from the Mesh Deformation solver.

Damping Factor
Displacements at the boundary are damped smoothly to zero starting at the specified distance. This factor is value Lp in Eqn. (4857). The default value of 0.0 means that the distances are calculated automatically.
Continuity Level
Specifies one of the following damping functions to be used in smoothing vertex displacements approaching the plane.
  • C0: The displacement is damped using Eqn. (4855). Only this option is valid when evaluating the mesh sensitivity.
  • C2: The displacement is damped using Eqn. (4856).
Ignore Factor
This factor is multiplied by the Damping Factor to calculate a finite distance. Control Points closer than the specified distance to this plane are given special treatment. A value of zero is acceptable.
