Week 2 Challenge : Surface meshing on a Pressure valve

AIM:

TO THE GIVEN MODEL, CHECK FOR THE GEOMETRICAL ERRORS AND PERFORM TOPOLOGY CLEAN-UP ACCORDINGLY. SET THREE DIFFERENT TARGET LENGTHS AS THREE DIFFERENT CASES AND MESH THE MODEL.

PROCEDURE:

• FIRST, IMPORT THE GIVEN PRESSURE VALUE MODEL IN ANSA.
  
• THEN, TO DO SURFACE MESHING IN ANY MODEL THE FIRST STEP IS BE CLEAR THE GEOMETRY ERROR AND INTERSECTION ERROR.
• TO CLEAR THE GEOMETRY ERROR, FIRST WE SHOULD KNOW WHERE THE ERROR IS THERE, FOR THAT NEED TO CHECK THE PRESSURE VALUE MODEL USING, CHECK OPTION IN TOP BAR.
  
  
• CLICK GEOMETRY IN THAT CHECKS.
  
• THE POP WINDOW WILL BE OPENED
  
• CLICK, THE EXECUTE BUTTON,NOW THE GEOMETRY ERROR IN THE PRESURE VALUE WILL BE SHOWN THEN WHILE CLICKING THAT ERRORS THE LOCTION OF THE ERROR WILL HIGHLIGHETED IN MODEL.
• HERE THERE IS RED COONS THAT MEANS THE SURFACE IS MISSING WE SHOULD FILL THAT COONS WITH THE SURFACE.
• FOR, CREATE SURFACE WE CAN USE NEW SURFACE OR FILL HOLE IN CONS CAN BE USED.
  
• WHEN USING THE NEW SURFACE, THE OPTION ARE EXISTING SURF, PLANAR, FITTED, COONS.
  
• IN EXISTING THE SURF, SELCET THE COONS WHICH SHOULD BE CLOSED AND THEN CLICK THE MIDDEL BUTTON NOW SELCET THE SURFACE WHICH IS ALREADY EXITING NEARER TO THAT SURFACE TO CREATED TO THAT.
• IN PLANNAR, SAME LIKE BEFORE SELCET THE COONS AND CLICK MIDDEL BUTTON IT WILL SHOWN SURFACE WHICH IS EXTUDED FROM THAT SURFACE IT MEANS SURFACE WILL BE EXTUDE FROM ORIGNIAL SURFACE TO BE CREATED.
• IN FITTED THE SAME LIKE BEFORE SELCET THE COONS AND CLICK THE MIDDEL BUTTON IT WILL SHOWN SOME ATR SURFACE WHICH CAN BE CREATED IN THAT THE AREA SO, WE CAN CHOOSE WHICH SURFACE IS CORRECT FITTED TO THAT AREA.
• IN COONS, SAME AS BEFORE SELCET COONS , AND CLICK MIDDEL BUTTON SURFACE BEEN CREATED AND CLICK OK.
• YELLOW CONS OR DOUBLE COONS WHICH WHEN THE SURFACES ARE JOINED THE YELLOW COONS WILL BE SHOWN ITS NOT AN ERROR.
• BLUE CONS OR TRIPLE CONS ARE COMES BECAUSE THIS 3 SURFACE ARE JOINED WHEN IT IS ESSENTIAL BLUE COONS WILL BE CONSIDERED, IF IT IS NOT MEANS IT SHOULD BE DELETED.
  
• AS BEFORE SAID THE RED, TRIPLE COONS HAS BEEN CLEARED USING THE NEW SURFACE OR FILL HOLE TOOLS.
• AFTER CLEARING THE ERRORS, THE GEOMETRY CHECK HAS BEEN CHECKED, THEN THERE IS NO ERROR ONLY WARNING, BUT WARNING ALSO BE CHECK IF IT CAN BE CLEARED, HERE THE TRIPLE CONS WARNING IS THE ESSENTIAL ONE TO CLOSE THE MODEL ENTRILY.
• AFTER CLEARING THE GEOMETRY ERROR, NOW WE NEED TO ASSIGN A ‘’PID’’ FOR ALL THE PART, FOR THAT CLICK THE PID OPTION TOP BAR HAS SHOWN IN FIGURE.,
  
• WHEN CLICKED THE PID, THE POP WINDOW AS BELOW FIGURE., HERE THE ONLY ONE PID IS ASSIGNED TO ENTRIE MODEL.
  
• NOW WE NEED TO CREATE NEW PID TO ASSIGN THE DIFFERENT PART IN PRESSURE VALUE MODEL FOR THAT CLICK THE NEW IN POP WINDOW CLICK PIDSHELL PROPEERTY AND THEN ENTER THE NAME WHAT WE NEED AND THE COLOR TO IT.
  
• NOW THE PID HAVE BEEN ASSIGNED TO ALL THE PARTS IN THE PRESSURE VALUE THE HAS SHOWN IN ABOVE FIGURE., NOW WE CAN HIDE THE ASSIGNED PID PARTS USING THE BULB BUTTON.
• AFTER ASSIGNING THE PIDS, THE INTERSECTION EEROR SHOULD BE CHECKED, FOR THAT GO TO CHECK AND THE CLICK CHECK MANAGE
  
• THE POP WINDOW WILL BE OPEN THERE CLICK EXECUTE BUTTON AND THE POP WINDOW HAS SHOWN BELOW THE IS OPENED THERE THE INTERSECTION IS SHOWN.
  
  
  
• HAS SHOWN ABOVE THE INTERSECTION ERROR CAN BE CLEAR USING THE TOOL CALLED INTERSECT IN THE FACES AS SHOWN THE FIGURE.,
• CLICK IT, THE POP WINDOW OPENS, THEN THERE IT ASK THE FIRST AND SECOND SURFACE.
• CLICK THE FIRST SURFACE AS COLUMN AND SECOND SURFACE AS SPRING CLICK THE MIDDEL BUTTON, THEN THE POP WINDOW SHOWS THE ALL THE INTERSECTION BETWEEN THE COLUMN AND SPRING
• USING THE KEEP AND DELETE OPTION THE INTERSECTION HAS BEEN DELETED.
  
  
  
• AFTER THE DELETING THE INTERSECTION ERROR, NOW CHECK THE MODEL USING THE CHECK MANAGER HERE THERE IS NO INTERSECTION ERROR BUT THE GEOMETRY SOME WARNINGS ARE THERE AS SHOWN IN THE FIGURE BELOW
• HERE THE TRIPLE CONS ARE ESSENTIAL TO DO THE SURFACE MESHING BUT THE CONVEX CONS COME WHEN WE DELETED THE INTERSECT BETWEEEN THE COLUMN AND THE SRING BUT THERE SOME CONS WHICH ARE NOT DELETEDTHERE, WHEN WE TRY TO DELETE THE THIS CONVEX CONS THE SHAPE OF THE MODEL IS CHANGES SO, WE CAN LEAVE BECAUSE IT IS WARNING ONLY IT WON’T AFFECT THE MESHING OF THE MODEL.
• NOW WE CAN START TO MESH THE MODEL BECAUSE WE SUCESSFULLY CLEAR THE ERROR IN GEOMETRY AND INTERSECTION HAVEN CLEARED.
• NOW CLICK MESH PARAMETER AND THEN ENTER THE MINI LENGTH AS 3 AND MAXIMUM AS 7 FOR TARGET LENGTH 5mm AND CLICK THE ELEMENT AS TRIA
  
  
• THEN CLICK THE QUALITY CRITERIA AND THEN ENTER THE MINI AND MAXI LENGTH AS THE 3 AND 7 FOR THE TARGET LENGTH 5mm
  
• THEN GO TO CLASSIC MESH AND CLICK THE LENGTH FROM THE PERIMETER AND IN PERIMETERS ENTER THE TARGET LENGTH AS 5mm AND MACROS ALSO 5mm.
  
• THEN CLICK THE CFD IN THE MESH GENERATION IN THAT CLICK THE VISIBLE
  
• THEN REPEAT THE SAME AS 5mm MESH BUT NOW CHANGE MINI LENGTH AND MAXIMUM LENGTH AS 1 AND 5 FOR TARGET LENGTH 3mm
• THEN REPEAT SAME AND CHANGE THE MINI LENGTH AND MAXI LENGTH AS 0.5 AND 2 FOR THE TARGET LENGTH 1mm.
• IN CASE THREE 1mm MESH IS MORE PERFECT THAN OTHER TWO MESHES SO, WE SHOULD USE THE 1mm MESH FOR THIS BECAUSE SPRING AND COLUMN IS NOT PERFECT IN OTHER TWO MESH.
  
  
  
• THIS IS FOR THE 5mm MESH LENGTH.
  
  
  
  
  
  
  
  
  
  
• THIS IS FOR THE 3mm MESH LENGTH.
  
  
  
  
  
  
  
  
• THIS IS FOR THE 1mm MESH LENGTH.
  
  
  
  
  

RESULT:

FROM THE GIVEN MODEL OF THE PRESSURE VALUE HAS BEEN CLEARED THE GEOMETRY AND INTERSECTION ERRORS THEN MESHED WITH GIVEN TARGET LENGTH AS 5mm,3mm,1mm ARE DONE.

CONCULSION:

FROM THE ABOVE MESHED SURFACES THE 1mm MESH IS MORE PERFECT THAN THE OTHER MESHED SURFACE.

LEARNING OUTCOMES:

• NEW SURFACE TOOL
• FILE HOLE TOOL
• ASSIGNING PIDS
• OR, NOT,AND, !NOT, ALL, INVERT,LOCK TOOLS
• PID REGIONS
• CHECK MANAGER
• MESH PARAMETERS
• QUALITY CRITERIA
• CFD MESHING
