Week 2 Challenge : Surface meshing on a Pressure valve

Surface meshing on a Pressure valve

• import the geometry from the file
• TOPO CLEANING
• fill the holes with fill holes option and the new face ----> coons
• 
• close all opensurface for water tight geometry .
• 
• PID: selection of all the entities of one selected PID
• PID region: selection of the entities of an unconnectedregion of one PID.
• select PID ----> PID REGION
• PID region is used in componets seperation when there is no conenction between the pid,s
• convert the child components and boundary surface into pid,s as (inlet ,outlet , base surface , valve head ,column ,spring,body)
• 
• 
• penetration issue fixing
• spring is penetrain with coloumn
• intersect them face -----> intersect 1 spring 2 column
• 
• identifi the unwanted surface in between of the components and delete it
• 
• MESHING PART
• MESH ------> PERIMETERS---> LENGTH 1)Perimeter ,macros
• MESH GENERATION ------> spot mesh
• Target length = 1mm, 3 mm and 5 mm (i.e. 3 cases)
• Element type = Tria
• MODEL 1
• Target length = 5 mm for whole geometry
• meshed pid wise and freeze it for to avoid mesh error in between the joints
• 
• 
• MODEL -2
• Target length = 3mm for whole geometry
• 
• measure the length between the node points
• 
• 
• MODEL -3
• Target length = 1mm for whole geometry
• 
• 

Report

• MODEL -3
• Target length = 1mm for whole geometry gives the good quality of mesh
• it occupid the whole surface of the geometry and give more number of elements in geomerty
