Speaker Grill Structure Modelling

Hello everyone,

 

I need advice about preparing mesh model of the small blind and open holes contained on the some speaker cover parts. I inspected shape factor and equivalent thickness using is useful way for modelling but i'm not sure is that best way for modelling with DD or 3D meshing. I tried standart meshing procedures (for DD and 3D mesh) mesh element amounts achive 4.5-5M. Solver and my pc capacity not run analysis due to too much elements amount.

 

Could you share your experiences with me about meshing strategy for like this parts?

 

Thanks,

Good explanation from Sachin here about shape factor comparison between DD, Midplane, 3D and Shape Factor method.

Hi,

 

Of course 3D is the most suitable mesh type for these features. But Midplane is more practical considering the long calculation time of 3D. And for big, shell-like parts, we nuormally use Midplane. If you want, we can introduce a China mesh vendor to you.

Hi simulators,

 

Personally, when it is possible, I use Midplane models.

It’s faster and quite reliable versus the reality.

 

In the areas with opened holes, I set the thickness of the material separating the holes.

In the areas with blind holes, I set the thickness of the material in the bottom of the holes.

Except if it is thinner than the one separating the holes.

 

Good luck.
