Week - 8 - Morphing

AIM:

1) Practice all the Morphing techniques that were shown in the video for Model-1.

2) Perform morphing for the Model-2 and Increase the Height of the Dog houses and Ribs.

MORPHING :

• Morphing is the changing terminology or it is used to change the shape or design of the component without any numerical input.
• It is the process of smoothly transforming topology as well as cross-sectional properties of CAE components. It has become an integral part of the process of structural design optimization in various CAE disciplines.
• The morphing requirements can vary from simple transformation of design feature to very complex interaction of various design optimization parameters.
• ANSA provides powerful pre-processing tools along with the superior FE and geometry morphing capabilities.
• Unique combination of ANSA functionalities and strategies developed using insights gained by working on various client processes provide a robust platform for design optimization applications in various fields. .

Automation and morphing tools last mile usability has been further extended to provide easy to use and simple to understand techniques.

Many of such solutions have been provided for setting up complex optimization model set-ups and are being used by major automotive OEM’s.For example:-

1]Maruthi Swift (Hatchback version) and Maruthi swift Desire (Sedan version of Brio).

2]Honda Brio (Hatchback version) and Honda AMAZE (Sedan version of Brio).

3]Toyota Etios (Sedan version) and Toyota Etios Liva(Hatchback version).

PROCEDURE:

• Morphing can be done in different ways.
• Here we are use FREE - FREE morphing method where we just morph the given CAD model at any direction we want so that it giving a new shape and new size.
• It is a basic step of morphing.

Import the given CAD model.

CAD Models [ MODEL 1 ]

Check for geometry errors for both the models and fix it if there are any.

GEOMETRY CHECK

We can fix these errors by AUTO FIXING by right clicking all the selected errors and selecting FIX option.

GEOMETRY CHECK

Now we can proceed with morphing techniques after correcting Geometrical errors.

Go to MORPH DECK

MORPH MODE >> BOXES >> NEW >> ORTHO >> GEOMETRY (Then select the faces for morphing).

[ MODEL 1 ]

Morphing Box

Here we can create boxes under morph module buttons.

This morphing box have control grid so this box will move along the control grid only.

Control grid can be moved by numerically or by our panel input which is based on the global co-ordinate.

Local co-ordinate system can also be made by right clicking the mouse andchoosing Entities.

A line in the morph window appears.

[ MODEL 2 ]

[ MODEL 2 ]

[ MODEL 2 ]

Extending

MORPH MODE >> BOX MORPHING >> MOVE >> SELECT NODES or ENTITIES >> Middle click >> Extend.

Movements of Nodes/Entities

Morphing Boxes

Once the morphing is done Morphing Box can be deleted.

Boxes >> Delete

Box morph can be split into number of entities to Morph it in much a simpler way.

This will create a number of additional boxes which may help us to do small changes to the CAD.

Splited Morphing Boxes [ Model 1]

LEARNING OUT COMES:

• We understand what is Morphing and different techniques to use in various Industries.
• Learned how to do morphing techniques using ANSA on CAD Geometery and create a morph boxes.
• Learned how to move morph box by selecting entities or nodes.
• Learned how to offset under morph mode.

CONCLUSION:

Successfully performed basic morphing technique by changing the length for the given CAD modeles.
