Improving the Mesh Quality for SAE BAJA Roll Cage
Hey everyone,
I meshed my roll cage using element size 5, checked the element quality after setting the criteria file to Opti struct solver, did smoothing & all stuffs, manually did the improvisation of mesh quality, but still some elements are failing. So, is there any way to improve the mesh quality even more and if it is so, then how?
Also, which parameters needs to be taken care off in quality index panel. I have ignored only taper & chordal deviation & tria parameters( min/max angle & % of trias) as i am only using quads and do not want to use trias?
Please help me out.
The major problematic areas are the regions where tubes are welded. I even tried to remesh those regions but failed to achieve the best mesh at the end.
Any help would be of great help to me

Split your surfaces to better control the mesh.
Begin with fine mesh:
And you got:
Have a look at my modified model in attachment.
In pratice, you can not do a "good" mesh with a good value for every criteria.
Take some criteria as important for you, like jacobian, aspect ratio,...
Another point: split your geometry and do fine mesh within critical area.
