Week 3

Aim:

To mesh the given component with ansa 19.1.5 as per the provided quality criteria

Procedure:

Import the model hood.step.asna

as the model is symmetrical it can be divided into two equals halves and the folowing procedure can be carried out.

check for the topological errors, red lines indicates free edges, cyan lines indicates triple cons 

use the geom clean option to remove the unwanted hot points, the delete option can also be used inorder to removet the unwanted hot points.

perform the topology opertion where the single cons are shown, except the edges.

check for overlapping faces, unattached faces and minnor hole as it is a part of the topology clean up procedure.

now extract the middle surface manually by faces-> offset and enter the offset value

do it for all the surfaces, as it can be done by selecting the surface on a whole.

after extracting the surface assign the surface to different lock views, by store lock optioin

it helps to uncomplecate the surfaces and its properties.

go to the mesh tab and start the meshing by selecting the surfaces.

the selected surfaces are meshed in mesh generation-> best mesh

if the flow of the mesh is distorted then the reconstruct option is used from the shellmesh block

then the perimeter mesh points are adjusted as required from option perimeters from the perimeters block

the mesh is adjdusted as required using the options provide from the options lists in ansa.

Result:

Thus the given model is meshed as per the quality crietria and assign property by adding thickness to it.
