Week 2 Challenge : Surface meshing on a Pressure valve

SURFACE MESHING ON A PRESSURE VALVE:

CHECK FOR GEOMETRICAL ERROR:

Check manager --> Geometry --> Execute

TOPOLOGY CLEANUP:

Using Cons --> Fill hole

Face --> Fitted, Loop

These are some of the option for topology cleanup. It will patch up, fill up where its necessary. Here AND,OR,NOT,ALL,LOCK options are used to add, restore,subtract some parts we needed. In PID, we create separate shell for inlet,outlet,body,valve head,spring,base,column.

THREE DIFFERENT TARGET LENGTH WITH TRIA ELEMENT TYPE:

TARGET LENGTH: 1mm

ELEMENT TYPE : TRIA

MINIMUM LENGTH: 0.5mm

MAXIMUM LENGTH: 2.5mm

TARGET LENGTH: 3mm

ELEMENT TYPE : TRIA

MINIMUM LENGTH: 1.5mm

MAXIMUM LENGTH: 4.5mm

TARGET LENGTH: 5mm

ELEMENT TYPE : TRIA

MINIMUM LENGTH: 3.5mm

MAXIMUM LENGTH: 6.5mm

TARGET LENGTH	ELEMENT TYPE	CELL COUNT
1mm	TRIA	216737
3mm	TRIA	24242
5mm	TRIA	8966

From the above cases, its concluded that case with 1mm target length has little to defeaturing and retained the geometry. Case with 1mm gives the best results and here is only more computational time.
