Week - 4 - 2D meshing for Plastic components

AIM

To extract the midsurface and mesh the given plastic component under the given quality criteria.

PROCEDURE

• The given component is import in ANSA.
• Change the DRAW MODE to ENT.
• Seperate the Plastic component by using store lock in look panel.
• And take one component and start the process.
• First geomentry clenanup is done for the component for that go to CHECKS-Geomentry and execute the process. If there is any openeing or free edges are present in the component are shown then to give fix option it will fix it automatically.
• 
• By using Fine option change the resolution of 3D curves or cons.
• Measure the thickness of the component in utilities panel before extracting Midsurface.
• Extract the midsurface by using offset option faces and use feature area to select one side of the component.Then click the midle mouse button and give the offset distance(T/2).And click no for deleting parent component option and then the midsurface is extracted.
• After extrating midsurface use fine option to change the resolution of 3D curves.
• 
• 
• Then change TOPO to MESH MODE and change the perimeter length1mm for whole component by length option in perimeter panel.
• 
• 
• 
• 
• Check all the surface by measure option if any surface is below 0.5mm use the JOIN or CUT option for defeture it.
• By using the align option change the nodes parallel to near nodes.
• And go to criteria file and change the vaue by given quality criteria.
• Then give the value for mesh parameter in utilities panel.
• Now generate the mesh for the given component by select the BEST option to mesh generation.
• Change the SHADOW to HIDDEN mode for view the failed elements.
• By using the Reconstruct option and change the meshflow for properly.
• 
• 
• 
• If there is any opposite tria or tria formed towards to perimeter must be changed by using swap, split,reconstruct option to change it.
• And use the smooth option to smooth the mesh flow.
• This process is done for all other components.
• And assign thickness for component but all has different thickness for that measure the thickness for all surface and seperate it.
• And give the required thickness.
• 
• Then assign the property for the component in data base panel.
• Give the proper thickness to all component and assign it.

CONCLUTION

Thus the given plastic component is extracted midsurface and meshed under given quality criteria.
