Assignment 1

AIM:

To extract the midsurface for the given component and mesh it with given quality criteria.

METHODOLOGY:

1. Importing the model.
2. Cleaning the imported geometry.
3. Extracting the midsurface for the geometry.
4. Meshing the surfaces with given quality criteria.

NOTE:

For all the models procedure is same.

PROCEDURE:

• Import the model from the folder.

Figures-1,2,3 (Importing the models)

• Set the user as ‘RADIOSS’ and select okay.
• Cleaning the geometry with appropriate tools.

Figure-4(Cleaning the models)

Figure-5(Cleaning tools)

• Go to geom panel, select ‘midsurface’.
• Select the surfaces and click on extract.

Figures-6,7,8(Extracating the midsurfaces)

• Hide the parent geometry and edit the midsurface if any.
• Spilt the model into small parts to mesh it.
• Set the quality criteria in quality editor panel and click ‘apply’.
• Change the view to by element quality mode.
• Mesh each segregated parts to obtain a good mesh flow.

Figures- 9,10,11( Meshed surfaces)

• Finds the errors and solve it with different options like

• Drag tria elements
• Element clean up
• Element Optimize etc

FIgure-13(Zero element failed)

Assign the thickness:

• Enable the parent geometry.
• Measure the distance at different locations and note down the values.
• Create a new property card in tool bar.
• Set the thickness value.
• Right click on component card and select ‘assign’.
• Select the property & material, and click on ‘apply’ and ‘ok’.

RESULT:

The midsurfaces are extracted for the given models and meshed the model with quality criteria.

Thickness is also to each component.
