Hi,

I am writing a script for automating blot assembly creation.

Some components like washer is having slot (OB Round) hole.

Initially I am creating 2D mesh and later I will drag it for each component.

Please find attached the image for understanding my query.

I have considered one quadrant and creating the base mesh. And then creating ruled mesh for each layer.

After creating the mesh, I want to split the elements using slot profile.

After splitting, we should maintain the Slot profile exactly.

And mesh should contain Only Quads.

But I am not getting right way to do this splitting

Please suggest a way to do this.

If any alternative methods are there for this type of mesh creation, that is also welcome.

Thanks in advance.

Regards,

Hari Krishnan. EL

I think you should create quad-only mesh between slot profile and OD

then drag that mesh to form Hexa

I don't think you can make 'quad-only' mesh with this kind of geometry.

Hi Tinh and Nguyen,

Thank you the replies.

I have attached the expected output of the mesh (Manually created).

We need some approach to achieve this kind of mesh.

Don't forget that : quad elements with 'bad quality' can't give you better results than triangular elements, from point of view of FEA.

my approach is:

1) make a surf

2) make profile lines

3) cut the surf by the lines

4) mesh quad only on sub-surfs

5) extrude to form hexas
