Week - 8 - Morphing

Basic of Morphing (ANSA)

Morphing

ANSA encompasses a full – fledged Morphing menu which is completely integrated with ANSA’s interface and doesn’t require any
additional module installations or licenses. The functions of the Morphing menu can be used to efficiently re-shape both FE and/or
Geometry based models.
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. The movement of the Morphing boxes control points defines the morphing operations on the entities inside the Morph
box. 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.
This method is extremely useful in creating local modifications on single parts. Creation of depressions, surface fitting 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
The desired morphing actions can be saved as parameters which can be accessed in batch mode. Users can enforce desired shape
changes by changing numerical input 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.
Morphing with ANSA
Reshape any type of FE without turn back to the CAD model for modification
Introducing parametric shape modification for optimization purpose
Morphing modification on both FE and Geometry
Two main methods
Box Method
Direct morphing

Direct morphing (without morphing boxes)
For local modification of simple component or assembly
Applicable on geometry and FE model
Different type of movements

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. The movement of the Morphing boxes control points defines the morphing operations on the entities inside the Morph
box. This type of Morphing can be applied to both FE and Geometry based models

Here we are using only Box morphing method to change the shape of the model
1.For doing morphing by box method, firstly we have to create the morph box, for that go to morph module then go to new option,
check out ortho and then go to geometry to create the morph box for the geometry, if we have FE then select FE option, after
that select the surfaces for which you want to change the shape, so for the selected geometry morph box is created
2.In box morphing by the use of grids and handles, we try to change the shape of the model as per our requirement
3.To move handles, go to morph box option then go to move, here we got two option to move handles one is free and other one is
value dependent (i.e. the value we defined), also we can split the morph box in order to get accurate result, or more precise
control

Moving the handles or control point in Y-direction to increase the height of the feature
After finishing the morphing means after reshaping your model is done, then we have to delete the morph box
