Project 1 - 2D meshing on the instrumental Panel

Aim:

       To check for the geometrical errors and mesh with the given element Quality criteria. After meshing the component the thickness has to be assigned.

Procedure:

1. Import the CAD model in ANSA.

2. Make topo and check for the geomentry error.

3. Clean up the geomentry error by automatic fix by ANSA or manual method.

4. Create the mid surface for the given model.

Manual offset method:

Here we enter the offset value and click ok.

Here the mid surface is generated.

Middle method:

By the middle option the mid suface of the two faces can genarated automatically.

Here the mid surface is generated.

For the dogs the curve is drawn in the surface of the dog and it can generated as the cross pattern mid surface.

Here the mid surface for the dog is created.

5. Set the quality criteria Tool Bar >> Quality Criteria (F11) >> Enter the Values.

Then click apply and ok.

6. To begin mesh,Switch form topo module to the mesh module. Before Meshing set the perimeter and macro length to the component.

Here set the perimeter and macro length as target element size.

7. To Mesh >> Go to Mesh Module >> Mesh Generation >> Best Mesh >> Select the area. 

Here the elements will fails it can be fixed by reconstruction of the mesh flow and also smoothing will helps to improve the quality of the mesh.

Here the mesh flow is completed without any quality issues.

8. Assign thickness to the components.

Mesh module>>Macro>>Set PID>>Faces/Shell>> Select the faces>> Middle click.

The property window will appeared.

Right click in that window Go to New>>Pshell>Pshell the new PID is generated.

Here give the thickness value and change the PID name.

9. After Assigning Thickness,Check whether the thickness have been appplied or not.

To check Go to Utilities >> Quality Criteria >> Presentation Parameters >> Draw Shell as
Solid.

Learning Out comes:

1.Various methods of extracting the mid-surfaces for various parts.

2.How to clean complex geometry.

3.How to extract a mid surface for doghouses.

4.Reducing the failed(Off) elements.

5.Assigning the thickness to the various parts of the component.

Conclusion:

    Hence the given component is  checked for the geometrical errors and meshed with the given element Quality criteria. And the thickness also assigned.
