Week 3 - 2D meshing for sheet metal
Aim:
To create mid surface for all the components in the given hood model and to perform meshing operation the extrated mid surfaces keying the given quality criteria
Procedure:
- import the given component to the ANSA work space
- check the all sub components in the model using the property command
- check the geometry , if any geometrical errors occur fix them
- ctake one of the component (part1) and check the thickness
- extract the mid surface either by manual offset method or mid surface generation option, as for the present part i have opted the manual offset method
now, after extracting the midsurface , perform the topo operation,so as to switch the all surface in the extracted midsurface
- create the property id and set the thickness value and name the part(part1)
- apply the newly created shell property to the extracted midsurface
- go the the meshing deck and give the element lenght as 5m
now, key the given quality criteria in the paramaters option and also set mesh maximum , minimum element values
- now, check for the node to node distance as it in between the maximum-minimum criteria if not use do the necessary changes
- we can use the project cut operation for complex shapes it divides the geometry as user requirments after applying the mesh in the projected area those projected curves can be joined by keeping the mesh as it is
- use best mest option and apply for the selected areas as shown
perform the mesh operation and check for the mesing quality errors if any reconstruck the mesh
we can also change the orientation of the mesh using split ans swap options , also based on requirements we can also hotpaints and perimeter optio for the alteration of the mesing areas
- first part the given model is as shown
note: for the part four curve edge of the surface altered while cleaning the mesh element setup
meshing of other elements as shown
after the meshing corrections check all the components in property tab with the original check geometries
