Project-2-Meshing of Door Inner Panel Challenge
OBJECTIVES:-
- Mesh Side door geometry based on criteria given
PROCEDURE:-
- open the hypermesh
- import the geometry by using import geometry option ,first select type of file then select the file ,click import
- Do correction for geometry error manualy by removing small fillet and make that coner into sharp edges by using surface fillet in defeature in geometry
- split total geometry into 4 part to generate mid surface easily and move to diffrent collector
- generate mid surface for each collector seperately by using automesh generation ,select extraction option as offset+planes and select incomplete solid
-
- compare generated mid surface with parent geometry ,if there any surface is missing then add that surface by using offset in surface edit and joint to existing mid surface
- if missing surface is mid surface of rib, then use final edit tool in midsurface and select both surface of rib ,joint mid surface of rib to midsurface
- some rib can are not in proper thickness ,for such feature take mid line for upper surface and project mid line into mid surface ,then create surface between this two line ,if this newly created surface not joined with middle surface extend it into middle surface
- after doing correction for mid surface , toggle the line which cause fail minimum element criteria
- input quality criteria preference- criteria file settings ,save file for later use
- select automesh from 2D mesh ,select surface appropriately ,adjust the mesh using moving triangle facing each other or touching each other
- select clean up tools from quality index ,and adjust element
- if necessary to rebuild mesh select rebuild mesh from 2d mesh and select element to rebuild
- after completing meshing for entire midsurface ,select edges from tools ,select a ll element ,check for free edges ,if there any free edges between element ,modify it with by using nodal paste option or equivalence option from edges
- delete free edges
- To assign thickness for complete element select map mid mesh thickness ,select surface as parent geometry ,select all element then click on calculate thickness
- finish the callenge
CONCLUSION:-
- Some special feature mentioned in this challenge to make mid surface by cross surfaces ,after meshing it didn't caught properly surface as parent geometry
- after 2d detailed element representation some element in same plane are little distorted
