Hi,

 

Is there a way to merge all the highlighted elements as shown on Fig1?

What is the best way to fix those elements shown on Fig 2 (detail on Fig 3)?

If you have any comments or suggestions about the mesh please let me know.

 

Regards,

Hi,

 

The geometry preparation or "cleaning" is an important key to produce a good finite element model, so take your time to properly cleanup your geometry before starting mesh.

I mentioned that gaps exist between several curves in your model and this will lead to nodes mismatch. 

Don't hesitate to use the geometry / surface / non manifold add to ensure that all yellow highlighted curves are presenting your desired free edges before meshing. You can also split your geometry (surfaces) in order to match the several parts edges. 

 

look at these videos :

Thanks for your comments, however, I still have that question about how to select a group of elements and merge them together to create larger element?

Give a try to Mesh / Remesh / Unrefine

I'm sure I'm missing something, when I use Unrefine, it doesn't remove the
boundary between the elements (doesn't merge them together), it's just
making all the selected elements flattened (maybe bringing them down to a
specific height,...)!, please see the snapshots below and let me know if
you have any comments.
