Week 2 Challenge : Surface meshing on a Pressure valve
AIM:-
Generate the mesh a pressure valve model using three different mesh sizes and find out the optimal mesh size.
OBJECTIVE:-
- Check for the geometrical error and perform Topology cleanup.
- Generate mesh using three different cases. Target length= 1mm, 3mm and 5mm.
- Element type is Triangular.
PROCEDURE:-
- Import pressure valve model from the files.

- Now click on the arrow>select checks>select Geometry>Geometry>Enable single cons>Execute.
- After execute shown as below,

- After the check the error we can clean or adjust the surface
- Click the face>new>select the different faces.
- Select the different types of face using the different applicition like coons,Existing surface,Planar,Fitted also using the fill hole option.

- After close all the open surface check the error for further operation.
- There are triple cone error show

- Using PID command generate properties like Body,Outlet,Inlet,Spring,Valve head,Base surface,Column with the different color


- We create the all properties of the model and after that move to the meshing.
CASE 1:- 5mm Length
- To mesh select mesh>length>perimeters>5mm>Marcros>5mm.
- After that mesh perameter given the value is maximum length is 7mm,Minumum is 3mm and the mesh type is Tria.
- Also given the value in the quality criteria command as maximum length is 7mm and ,minimum length is 3mm.
- After the set the length select the spot mesh option and generate the different part of geometry.

Mesh of Valve head

Mesh of Spring

Mesh of column

Result:-
The total number of element are 8210.
CASE 2:- 3mm Length
- To mesh select mesh>length>perimeters>3mm>Marcros>3mm.
- After that mesh perameter given the value is maximum length is 5mm,Minumum is 1mm and the mesh type is Tria.
- Also given the value in the quality criteria command as maximum length is 5mm and ,minimum length is 1mm.
- After the set the length select the spot mesh option and generate the different part of geometry.

Result:-
The total number of element are 23749.
CASE 3:- 1mm Length
- To mesh select mesh>length>perimeters>1mm>Marcros>1mm.
- After that mesh perameter given the value is maximum length is 2mm,Minumum is 0.5mm and the mesh type is Tria.
- Also given the value in the quality criteria command as maximum length is 2mm and ,minimum length is 0.5mm.
- After the set the length select the spot mesh option and generate the different part of geometry.

The total number of element are 209391.
CONCLUSION:-
- From the all cases it's concluded that the case of 1mm length has little to no defeaturing and retained the geometry of all components.
- 1mm case give us a best result and we can see that it is more refine.
- We can say that for better results we can decrease the length of mesh so we can get better results and more number of elements.
- Also we can see the individual part mesh for different mesh size.
