Week 6-Meshing of Hood Challenge

OBJECTIVE:

mesh the component given below and assign thickness:

Target Element Length = 5 Units.

this is the quality criteria which has to be maintained in meshing of hood panel.

PROCEDURE:

Open the hypermesh software,import the model.

after importing the model,click the F key to get the view of the component imported.

now cleanup the model.

both manual method and automatic method can be preferred.

it is easy to cleanup the geometry automatically.

geometry cleanup includes adding the faces that is being missed.

some extra surfaces.

free edges.

these errors should be removed.

after removing these errors,take the mid of the parent model.

now the midsurface should be checked for perfectness.

there should be proper surface formation without deviating from the parent model.

it is general to be deviated at complex surfaces, where lines and fillets are being involved.

so, check those areas properly.

now the next procedure is meshing.

before meshing there is some criteria should be followed.

enter the quality criteria that is given in question.

now to get the proper meshing, the target lenght be known and have it in mind.

the unwanted construction lines must be cleaned and oriented properly.

the inclined lines are made straight.

the space between lines which is less than target lenght must be removed.

because the space causes the quality errors.

but if the space is greater than mininum lenght criteria then it can be accepted.

the small fillet regions can be removed.

the features should not be touched unless it deviates from minimul lenght.

some feature lines should be moderated particularly at some points where the space between lines is low.

after clening up the geometry, washer split can be provided.

after these procedures its time to do mesh.

the above image shows the component after cleanup.

now mesh each part by part.

after meshing check for any quality errors.

if the mesh is not proper then uses rebuild command to get good mesh.

trias are not advised to be in perimeters,back to back or conjusted.

midsurface is seen to be symmetrical with respect to middle line.

so the one the surface can be deleted.

then do the meshing for all the parts.

after meshing reflect it.
