Query in Split Element using Curve/line

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.

    Hi

    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
