Assignment 1-2D Meshing Challenge

Objective -

Procedure -

MODEL 1

1. Chech for geometrical errors and rectify them as shown below :

Use the filler surface command to create missing surfaces.

Create new surfaces wherever necessary from the surfaces - ruled command as shown :

Toggle and re Toggle T Joints wherever necessary as shown :

More rectifications in the geometry have been carried out as shown below :

The geometry after no free edges is as shown below :

2. Extracting Mid Surface :

To extract the mid surface we first measure the thickness of the component by clicking F4 on the keyboard & using the 2 points option as shown below :

3. Defeaturing

For holes <5 mm we use the unsplit surface option in the quick edit panel as shown below:

Defeaturing surface fillets wherever required is carried out as shown :

Defeaturing edge fillets wherever required is carried as shown :

4. Enter the quality criteria as shown in the criteria editor :

5. Mesh the model and refine the mesh according to the quality criteria, the final mesh is as shown:

6. We create a new property card and assign the thickness of the component, after assigning thickness we switch on the detailed representation of the mesh, the final result is as shown :

MODEL 2 :

After opening the model and inspecting it, we find that there are no geometrical errors present in the model :

We proceed for the mid-surfacing of the model as shown :

After the creation of the mid surface we defeature the fillets & remove holes as shown :

We mesh the model and refine the mesh :

We create a new property card and assign the thickness of the component, after assigning thickness we switch on the detailed representation of the mesh, and the final result is as shown :

MODEL 3:

The model is opened and checked and no geometrical errors were found :

We proceed for the mid-surfacing of the model as shown :

After Midsurfacing we toggle edges so that elements do not fail for quality criteria:

We mesh the model and refine it :

We create a new property card and assign the thickness of the component, after assigning thickness we switch on the detailed representation of the mesh, the final result is as shown :

Learning Outcomes :

Learnt to model components in hypermesh.

Learnt to defeature geometry.

Learnt to assign thickness to a component and create property card.

Result:

All the three models have been meshed in accordance with the quality criteria given.
