Week 2 Challenge : Surface meshing on a Pressure valve

AIM-TO STUDY SURFACE MESHING ON GIVEN GEOMTRY,MAKING DIFFERENT MODELS WITH 3 DIFFRENR TARGET LENGTH

GIVEN GEOMTRY-

WE CAN SEE THERE ARE MANY SINGLE CONS AND OPEN HPLES IN GEOMTRY

SO WE CAN PERFORM A GEOMTRY CHECK IN ANSA

AFTER EXECUTING WE CAN FIND ALL THE ERROR IN THE GEOMTRY WE CAN WORK ON THEM ONE BY ONE

FIRST OF START THE OPEN THE ANSA SOFTWARE

THEN OPEN THE MODEL

THEN THE FIRST OF ALL PROCESS CHECK RESULATION

THIS PROCESS TOOL-SETTING-RESULATION -SELECT LENGTH-PARAMETER -PUT VALUE AND CHANGE RESULATION

THEN THE PROCESS CHECK UNIT IN MM OR M

THEN THE PROCESS CHECK ORIENT

FACE-ORIENT-AOTO YELLOW-CHANGE ORIENT

THEN THE PROCESS FILL HOLE SURFACE AND CLEANUP THE GEOMTRY

CALLIC TOPPO-NEW SLECT CONES- MIDDLE MOUSE CLICK -DONE

THEN ASSIGN THE PID WITH NAME

FACE-SET ID-SELECT MACROS MIDDLE CLICK

1. BODY
2. COLUM HEAD
3. COLOUM
4. INLET
5. SPRING
6. OUTLET

THEN AFTER PID ASSIGN DO SURFACE MESHING ON DIFFERENT ELEMENT SIZE MESSING PROCESS=SHELL MES CLICK-THEN SELECT SPOT MESH -THEN SELECT ENTITY-THEN PUT MIN LENT AND MAX LENGTH -THEN CLICK LENGTH PARAMETER THEN PUT THE VALUE THEN -SELECT MACROS AND PUT VAUE AND SELECT ENTITY MIDDLE CLICK DONE

ELEMENT LENTH =3,MIN LENGTH=1 MAX LENGTH=5

CUNCLUSION=

1. WITH FINE MESH SIZE THE ACCURECY INCREASES BUT TIME FOR CALCULATION ALSO INCREASES
2. WE CAN MAKE TWO DIFFERENT TARGET LENGTH ACCORDING TO TO THE SIZE OF PART AND REQIRED ACCURACY ,IN CASE OF OUTER CASING MESH SIZE CAN BE 3 MM WHICH IS NOT SO LARGE AND NOT THAN EITHER FINE FOR GOOD ACCURATE RESULT
3. FOR THE SMALLER PART OF SPRING AND THE COLUMN HEAD THE MESH LENGTH CAN BE 1 MM SO THE ACCURACY FOR SMALLER PART INCREASES.
