Week 9-Creation of 1D Connectors Challenge

#9 Week Challenge Hyper-mesh for FEA Plastic and Sheet Metal Applications

Aim: To Mesh the given components by giving the target Element Length as "5 units" by using the quality criteria as below:

Import the geometry;

1. Click on the import icon on the main menu bar.

2. Click on auto-mesh and enter the target element size as 5 units.
3. Select the type as tria elements, give the minimum and maximum element length in the criteria file.
4. Click on the surfaces and select the displayed surfaces, make sure the component is made as current component.
5. Click on create mesh, check for the elements failed and re-mesh the elements.
6. Check the elements for quality before starting the connectors,

Connector Rules:

1. Connectors has to be created at the component attachments.
2. Click on create, you can see the connector is created, realised in the status bar.
3. Open the connector from the view >browser > Hypermesh > Connector, here you can see the connectors that has been created.
4. Red indicates the connector is created but not realised.
5. Green indicates the connector is created and also realized.
6. Every connector created must be realised.
