Procedure To Accomplish The Given Task:-
Step1:-
We have to Download the model and import it into ANSA software.

Step 2:-

I did TOPO to connect all the cons and surfaces in the given geometry.
Step 3:-

I Fine the surfaces to know exactly how that surface is so that it is easy to understand how to from new surfaces.
Step 4:-

Building surfaces to correct the geometry.

I connected all the surfaces.

I had runner a geometry check to confirm the geometry to proceed further.
Step 5:-

I started making mid-surface setting up property individually for every surface.
Step 6:-



I connected all the surfaces after taking all mid-surfaces.
Step 7:-


I also took mid-surface for side ribs.
Step 8:-

Before meshing set the length to the target element through the surface it will help in forming a good mesh flow.
Step 9:-

I started making meshing.

Meshing the surfaces connected one by one so that we can correct the mesh flow.
Step 10:-

To get a better mesh flow clearing the maximum tria's is important.

Pasting hot points can reduce the trias in the mesh. Se like this we need to reduce the maximum trias we can to maintain better mesh flow.
Step 11:-

Like this, I cleared trias first in the created mesh which will make me concentrate on other surfaces further.
Step 12:-

I meshed all the surfaces and completed the meshing.
Step 13:-


Property is also assigned to each and every surface according to their respective thickness.
Step 14:-

See the thickness also assigned as instructed in the task.
Result:-
By completing all the corrections we completed the task according to the given criteria.

Followed the below-mentioned quality criteria and mesh the components given and assign thickness too:
