BOTTLE CAP MODEL

• Opening model and check for geometry errors.

1. Click on file and open bottle cap model file. Then open presentation paramerters and reduce detail on demand. Then checking for geometry errors And removing errors using combination of \'UNIVERSAL DELETE, TOPO, RELEASE, AND PASTE. Then running geometry check tool for any topology error.

• MID SURFACE EXTRACTION OF BOTTLE CAP AND SETTING PID\'s.

1. After geometry check extracting mid of botttle cap using manual method. first need to check the thickness at different places using meausure tool for better mid surface extraction.
2. Then using \'inot, not, and, or\' just to making outer body of cap visbile for botter visibily of model. Then extraction of mid surface of cap using set of commands like \'middle and offset\'. And using topo command to join two cons. After extracting mid for all component of cap and run geometry check tool for any errors. a. offset command is used to create a face at some distance of original face. b. middle command is used to create a middle face from two selected faces.
3. Take middle for ribs using offset command and join them to main mid surface. to do that use \'cons2curve\' and selecting cons and press middle mouse button to make curve on selecting cons. Then moving curve using \"move\" command and then using \"new \' command to make new face, now extend to main body.
4. Checking for geometry check for mid surface.
5. Setting Pid\'s to inner wall of cap using command \'setPid\' from \'faces\' then selecting surface of cap press middle mouse button, new dialog box opens, right click in dialog box select new, then assiging thickness and proving names to part then click OK. Now creating pid\'s for all component of cap and providing names like inner, outer wall \'and ribs of cap.

• GENERATING MESH WITH IN QUALITY CRITERIA

1. Genetrating mesh on botttel cap model component one by one using \'BEST\' option from mesh generation. But first set the perimeters or element size as \'1mm\' Select whole model and press middel mouse button to confim. To apply mesh select \"best\" then select the component and middle mouse button to confirm mesh, and also checking for good mesh flow. For good mesh flow there should not be two trias pointing at same direction. To remove the trias using swap, split command and pasting nodes. now removing off elements using command explained below.
2. To remove the off elements using commands \'CUT,JOIN, SPILT, MOV SURFACE,paste nodes, DELETE HOT POINTS, SWAP, RECONSTRUCT MESH, and creating removable cons to eliminate off elements.

CUT COMMAND : Cut command is used to remove double cons or to remove unwanted coons which creating off elements.

SPLIT AND SWAP COMMAND : Split command is used to split the quad element into tria element which can create tria using nodes or edges of element. and swap command remove the edge and paste to adjecent edge.

MV SURFACE : Move surface is used where minor change in placement of nodes of elements can eliminate off elements.

RECONSTRUCT MESH : Reconstruct mesh is used to create mesh on meshed surface.

PASTE : Paste command is used to paste two nodes and remove tria element.

SMOOTH : Smooth command is used after correcting some mesh flow, to smooth the mesh throught out the selected area of surface.
