Morphing Overview:

ANSA encompasses a full – fledged Morphing menu that executes specific requirements. This menu is completely integrated with ANSA’s interface and doesn’t require any additional module installation’s or licenses. The functions of the Morphing menu can be used to efficiently re-shape both FE and/or Geometry based models. This way, a multitude of complete meshed models may be created for optimization and other CAE processes.  The application of morphing can be found in any discipline: Crash, NVH, Durability, CFD, etc.

Domain (Box) Morphing:

Domain or Box Morphing is preformed via boxes that are created around a particular part or assembly that the user intends to morph.  These Boxes are loaded with any kind of entity within ANSA.  The movement (translation, rotation, transformation or a user free movement) of the Morphing boxes control points defines the morphing operations on the entities inside the Morph box.  Assemblies and full system models are uniformly morphed when locally updating an area when using the Domain (Box) Morphing tool. This type of Morphing can be applied to both FE and Geometry based models

Direct Morphing:

ANSA’s Direct morphing features gives the user the ability to efficiently modify a part locally without having to create Morphing boxes.  These functions allow the movement of selected entities as one rigid body. This method is extremely useful in creating local modifications on single parts. Creation of depressions, snapping certain FE part features to new target geometry, moving selected features along the contour of a surface and also the ability to freeze (rigid) elements during the morphing process are some of the direct morphing abilities.

Parametric Morphing:

Most of the basic functions of morphing can be handled through specific parameters. The morphing parameters control morphing entities such as boxes, edges, faces and control points.  Once defined in the model, the user can enforce desired morphing actions by changing a numerical value for the appropriate parameter. This method of morphing is highly utilized for coupling of the morphing operations to an external optimizer. The scripting capability can be used in conjunction with ANSA’s parametric morphing functionality to deliver faster DOE models.

Geometry Morphing:

ANSA brings to the CAE world its ‘one – of – a kind’ tool for CAD geometry morphing. This pioneering concept allows the user to utilize the inventory of all the familiar FE morphing functions to perform equivalent operations in a CAD environment on geometric entities.  The built – in functions such as the geometry check, keeps a tab on the morphing operation, so the user will always have a valid geometrical model for meshing.  Investigation assistance functions help in resolving such conflictive situations.

Optimization Coupling:

One of the biggest advantages that ANSA delivers is the ease with which it can be coupled with an optimizer. An optimization task is a pre-processing sequence that works based on design variables, while following certain design constraints to achieve the final design objective.  ANSA’s morph parameters form as the link to the optimizer’s design variables.  This way ANSA can be setup to be invoked in an optimization loop and will be executed in a pre – defined order modifying the model. Most of the FE entities in ANSA can be parameterized through ANSA parameters, which facilitates for their use in:
  • Shape Optimization
  • Topology Optimization
  • Gauge Optimization
  • Spot – weld Optimization
  • Composite Optimization
The Coupling of ANSA with an optimizer displays ANSA’s performance and versatility to the process of optimization cycles and their coupling with codes such as:
  • LS-OPT
  • iSIGHT
  • Mode Frontier
  • Tosca; & others.
