Aim
To carry out the geometry cleanup operation of the following files:
1.Practice
2.Clip Repair
3.Mounting Bracket
PART-1
OPERATION-CLEANING
It is important do geometric cleaning of the part so that all the open edges and surfaces are filled or deleted so that a proper mid surface is created.The geometric clean up of part 1 is shown below:
Tools such as toggle edge with tolerance 2mm and filler surafce were used to carry out the cleaning operation.
OPERATION-MID SURFACE CREATION
Using the midsurface tool the midsurface was created so that meshing could take place in the next operation
OPERATION-2D MESHING
The meshing was carried out with use of quad as well as mixed elements as shown in the images. A washer element was created around the hole which is bigger than 6mm this was done to get a proper meshing around the hole .
Element thickness of 3.5 mm was used to get good no of elements as shown.Operations such as smoothing were also carried out.
PART-2
Unmeshed Part
It can be seen that there is no need of geometric cleanining hence we will directly move to mid surface creation.
Midsurface Creation
As you can see ,a new mid surface is going to be created using midsurface tool.
A midsurface is created as shown:
Meshing:
As the hole is bigger than 6mm ,a washer surface of thickness 3mm is created near all the holes so that good amount of nodes are created for meshing.
Meshing is done using 3.5mm element size and using mixed meshing elements that is quads and trias to get all the areas covered.
PART-3
Uncleaned part3
Creation of midsurface
Since the hole are less than 6mm,they can be ignored for washer surface for meshing
Meshing
