Objective

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. (Refer Red annotations in the below image to understand what are Dog houses and Ribs)

Model 1

Import the model in ANSA and perform topo and orient operations

Perform geometry check and fix any geometry errors

Then go to morph menu

Go to Boxes à New à ortho and create boxes around the macros that you want to morph

Select the nodes that you want to move.

Go to box morphing à move

You can either move the freely or up to a certain specified distance

Changed shapes

The fillet shape was changed freely

The last panel was extended upwards

Then it was offset by using the offset command

Model 2 – Hand rest

Procedure is same, just create boxes around the ribs and objects mentioned above and move them up, in this case, by 10 mm

Applications

Morphing is mainly applied when the design must be changed, updated or optimized.

In this case morphing saves a lot of time as you don’t have to recreate a completely new geometry.

Automobile industry

Used extensively to study vehicle structure changes and for aerodynamic modelling.

Ship design

Used in ship hull design as it saves a lot of time

Biomedical research

To determine the biomedical response of a structure, implant positioning and virtual bone modelling.

Conclusion

Morphing commands have been used to change the shape of the models as per given requirements.
