CHALLENGE 2

OBJECTIVE:

TO Clean up the topological error & Mesh the pressure valve with various element

MESH USING PROCEDURE:

- To open the ANSA software in pc

-To click open the file in selected folder pressure valve

-The selected file will appear in ANSA it\'s in wire frame mode ,enable the shadow mode to select ENT - PID option

-To select top of the area Quality criteria--->Presentation parameter {tick} mark in draw a cons,inPID,MID.....Apply click ok

-ctrl +shift+left key ----> no shadow mode

-To select [- not] part of the valve set pID -PID Reg select middle mouse button to confirm & invert option to see the inside the valve

- Individual Edges called COONS-- gap part to be fixed in surface,to correct the topo error single edges into double edges

- In faces option CUT---> SELECT--->HEAL CUT....its also not fine so ,go to another method to fill the holes in CONS--->FILL HOLE it is the best option to create & fix after disenable the cross hatches & drag --delete the HOT POINTS

-INVERT option to select !- -->PID Reg see the inner component of the valve

& spring seal

- Tackle the intersection--->FACES --->INTERSECT group selection *first *second middle mouse button to select 1st or 2nd

- BOOLEAN operation new edges are formed ( BLUE) in colour called Triple cons

Use !- & ENT to select surface & hidden the selected part

- if we want to delete the internal spring PID---> faces--> delete the selected inner part of the spring after cut out will made

- same as it is in bottom also FACES ---> INTERSECT --> SELECT 1st & 2 nd triple cons are formed ,ctrl + left key to navigate the position of the part ...

- Universal delete option to delete the ENT or PID selected double edges ....cut out was made successful

- select ALL option to visible all the component SURFACES -----> COONS -->loop option to create the surface perfectly

- To check the GEOMETRY unselect the triple cons , it will execute 100% successfully

- To Set PID -->Select the FACES middle mouse button -->NEW --> SHELL PROPERTY assign as INLET ,WALL& OUTLET

- Go to !- option in PID only select & hide the unwanted external part

-PID selection mode valve &spring are selected,we need to set seperate Set PID of valve and spring in this we used FEATURE AREA it selected{40 degree}less than angle spring get selected,corner edge of the area are not selected in this ENT -->select corner edge spring are selected manually

-In !- &PID reg valve get selected to assign set PID --> NEW -->VALVE double click to colour ok...

IN MESH MODULE :

-In mesh generation -->spot mesh below the option list select into tria mesh to regenerate & visible

-To select the mesh mode , perimeter ---> length drag the componenet middle mouse button to set length as 15, 7, 2

e In 7 UNITS its not fine {curves are not clearly visible } .

- In[ length 2 unit is the perfect clear visible of bottom surface area]or other than 15 ,7 are not clear visible of bottom surface area .. In this length

2units are good perfect visible ........so i used to choose 2 units are Best ....

conclusion:

Hence It is proved successfully ,topological error & mesh proccess are Done.......
