Week 4
BOTTLE CAP MODEL
AIM: To create a mid surface and mesh with the given quality criteria and to make sure the element is free from geomentrical errors.
PROEDURE:
STEP1: The file is dowloaded initially, to open the file ANSA>>given command argument>>OK>>CLICK ctrl+o>> select the file>>click ok.
STEP2: The errors should be checked by doing topology. For topology,CLICK TOPO>>select model>>middle click on mouse.
STEP3: PID is used to create a particular model part or the total model. To create a new PID or to check the existing PID, CLICK lists>> properties.
STEP4: For mid surface creation, CLICK utilities>>measure>>select the nodes>> CLICK the thickness at different location .
STEP5: By creating the rotating element mid surfacing we can reduce time and to perform a better flow of midpoint transform(rotate) is used.
STEP6: The curved filled mid surface height is difficult to determine . we can change the curve fillets to and angular corners without changing the model . CLICK dach(in faces buttons)>>dach
STEP7: Thickness of given model varies from feature to feature. to create a proper mesh flow ,thickness is added to individual feature
STEP8: Setting the quality criteria and meshing parameter before proceeding with the mesh, the quality criteria and meshing parameter are to be given to meet the requirement . By clicking utilities>>quality criteria
STEP9: Creating the mesh flow:
to create a mesh for any model, CLICK module>>mesh once the mesh module buttons are opened and seen .
STEP10: Adding thickness to the mesh, the thickness of the mesh can be added in the property icon and by selecting the part to which the thickness needed to be given.
TERMS USED
TOPOLOGY: Topology gives the shape and structure of the model
PID:PID means property ID. it generally gives a definition or class to particular part
MID SURFACE: it creates a surface on the mid plane which can be used to mesh. the mid surface is a projection of the main surface which is projected at the center
RESULT:
The proper mesh is created with no errors and mid surfacing of bottle cap along with quality criteria and thickness.
