OBJECTIVE

In this challenges we have to extract mid-surface For the given component, check for the geometrical errors and mesh with the given element Quality criteria. After meshing the components, the thickness has to be assigned. 

PROCEDURE

• Import the model into the ANSA and check the property, thickness etc.

• Then go to utilities – checks – geometry check to do geometry check whether any free edges, cracks on the surface of the components.

• Then topo the surface to clear the free edges and unwanted cuts.
• Then give the topo – faces – orient to orient the all surface.
• Measure the thickness of the components.

• Then extract auto mid-surface by topo – faces – mid-surfaces – skin but the auto mid-surface shows error so we go for manual mid-surface using topo – faces – offset and use 

  topo – faces – middle to extract middle surface of the ribs.

• Then create new PID for the mid surface of the components and assign thickness.
• Before meshing the components give perimeter length and macros length, by mesh – perimeter – length.
• Then give the mesh parameters in utilities – mesh parameters.

• Then give quality criteria by clicking F11.

• Then to achieve the quality use mesh – shell elements – reconstruct/smooth.

CONCLUSION 

            Finally the bottle cap CAD geometry is converted into FEA model with required quality parameters by extracting the mid-surface and assigning the thickness.

LEARNING OUTCOMES

               In this tool test  learnt how to extract the mid-surface of the plastic component and converting them into FEA model within a particular time. it takes 4hr for switch geomentry and 2.30hr fir ip to converte them to FEA models.
