Week 3- Geometry cleanup and Mid-surfacing
To extract mid-surface for the tube model and provide a connection with sharing option at the tube joint location
Solution:
The following steps helped in obtaining the mid surface of a component and provision for connections among the tube elements.
step1: Import the geometry from the given source.

Step2: Select the prepare tab and select the mid surface option.

Step3: Select the tubes one by one selecting the 'Select range' option and assigning the thickness value. The thickness value for tubes ranges from 0mm to 6mm.
Step4: Go to workbench option and select sharing. The faces will be selected and sharing will be assigned among the faces.

Case 2:
Create a model in Spaceclaim one on top of each other and create a shared topology between the top block and the bottom block.
Dimension of Top Block A: 20 x 20 x 5 mm
Dimension of Bottom Block B: 40 x 40 x 10 mm
Boundary Conditions: Provide Fixed support for the bottom face of Block B
Perform a modal analysis (free-free run) to verify connections and analyze the results.
Solution:
Step1: Access the Spaceclaim interface.
Step2: Select rectangle B and select centre point to create a rectangle for the given dimension of 40mm x 40mm with extrusion of 10 mm.
step3: Select the upper face and draw rectangle A with the similar selected options with a dimension of 20mm x 20 mm with extrusion of 5 mm
Step4: Select split body from the workbench tab and split the two bodies.
Step5: Select sharing option form the workbench tab and create connection among the two bodies.

Step6: open ansys workbench and drag the modal analysis tab to the workspace.

Step7: Open design modeller, and select mesh option to mesh the 3d model.
Step8: Select fixed support and select the lower face of rectangle B.
Step 9: Open analysis setting to select the number of modes to find.
Step10: Select total deformation in the solution settings.

Conclusion
The spaceclaim environment and the different functions used for building 3d models were studied and the models were build using spaceclaim. The ansys environment was also studied and the modal analysis was done on the model.
