Using basic morphing techniques to achieve a required change in the given CAD model using ANSA

Objective:

To use Morphing techniques to make changes to the CAD model of the given component.

Procedure:

1. Open the model.

2. Perform a TOPO on the model and orient the model. The model will look as shown below:

3. Go to the Morph Deck.

4. Go to Boxes -> New and create a new box around the area of the CAD geometry that needs to be morphed as shown below:

5. Go to Box Morphing -> move and select the nodes to move as shown below:

6. The original model and morphed model will look as shown below:

Original model Morphed Model

7. Next we move on to another region of the model and follow the same steps to achieve the required shape as shown below:

Original model:

Morphed Model:

8. We move on to another region shown below and perform the same operation.

Before Morphing:

After Morphing:

9. Another we can also create a new box on the entire model and morph the whole model at once.

Before morphing:

After Morphing:

10. Before submitting the final model, the boxes that were created needs to be deleted.

Learning Outcomes:

• Morphing basics

Mesh morphing is used to create shape parameters which include changing a length, an angle or a thickness, it can be used to change one shape into a new known shape which is a better CAD model as given by the CAE solution.

Examples where this is used:

Automobile Industry:

Small changes in the CAD model of a car can be meshed easier by morphing rather than spending time re-meshing the component.

Biomedical Industry:

Changes in bio-medical components like bolts/ bone reinforcements/ stents

• Creating morph boxes
• Splitting morph boxes
• Moving morph boxes to achieve the required geometry

Thus basic morphing techniques were performed on the given CAD model.
