Hi everyone,

 

I encountered a problem when I created the trimesh for a containership (DTC).

I already created the parametric ship hull and wanted to export the "stl" file.

But the trimesh I created was not good ennough, there was a gap at the bow part of the ship hull, showed in the attachment.

 

Is anyone can fix this problem or is anyone has parametric ship hull of DTC ( That would be the best)?

Thanks a lot.

 

With regards,

Yanxin

You can throw them into a Brep and use a trimesh on top ot that, see attachment.

Cheers

Hi Claus,

 

thanks for your reply. I checked the trimesh on top of Brep. But the quality of trimesh seems not very well, is there any way to improve the quality of this trimesh?

Coz when I created trimesh directly on surfaces, I could edit the Tessellation of each surface one by one. In this way I could get better trimesh.

 

Regards,

Yanxin

Hi Claus,

 

I will explain it with those screen-shots in attachment.

The first one is the goal trimesh I wanted to achieve. It looks clean and nice. And the second screenshot shows how I can edit the trimesh of each surface. The last screenshot is the one piece trimesh of Brep. I am not very sure whether it will effect the simulation phase when I combine GLRankine with CAESES.

 

Regards,

Yanxin
