Week 2 Challenge : Surface meshing on a Pressure valve

Aim : Surface meshing on a pressure Valve .

Given data :

• Target length = 1mm, 3mm, 5mm
• Element type = Tria

Procedure :

Download valve file from dashboard.

• open ansa software
• select " CFD " & " PERFORMANCE MODE 3"
• Open downloaded Valve file
• select Shadow display mode
• 
• clear all RED COONS ( CONS - FILL HOLE & FACES - NEW )
• 
• Delete some extra part from body
• 
• select Faces - delete - select part ( shown part no. )
• after filling all red coons , go to Geometry check
• 
• 
• Here we see 1 IntersectionError are visible.
• 
• so we have to clear that .
• select 'NOT' option
• 
• select a part that we don't need ( temporary remove )
• 
• after removing parts do not forgot to 'LOCK'
• 
• then go to PID & creat a New PID ( PROPERTIES ID ) - select new - shell property.
• select PID region & apply it .
• 
• after PID assigned go to intersect
• 
• select 1st part ( here we select 1st part as spring )
• 
• then select 2nd part ( column )
• 
• delete extra parts
• 
• a
• 
• then click 'ALL'
• after clearing all errors go to meshing . set minimum length 0.5mm , maximum length as 1mm . - OK.
• 
• set quality criteria - min. length 0.5mm & max. length 1mm - APPLY - OK
• 
• then go Classi. - Perimeter - length ( set 1 mm )
• mesh generation - CFD mesh - visible
• 
• after meshing -
• 
• 

Out of 1mm, 3mm, 5mm the result of 1mm meshing is great . All parts are equally divided . So the meshing is done well.

here we see 3mm meshing :

5mm meshing :
