penetration between solid components

gslee

Hi,

 

I heard that Penetration is defined as the overlap of the material thickness of shell elements, while Intersection is defined as elements that actually pass completely through one another.

 

My model is as follows.

 

Thickness of the Solid component 'top' is 1T.

 

When I make 'bottom', I use 'translate -> duplicate-> z-direction -1'. (Thickness of each component is 1T.)

 

So I think there is no overlap between 2 solid components.

But Penetration check tool detect penetrations.

<?xml version="1.0" encoding="UTF-8"?>

 

Why does it happen?

 

It means there is overlap between 2 components?

 

Thanks

Can you show your interface details? If you read up on interfaces, you will note there is a value called gapmin. This value defines at which distance your components begin to interact. If your gapmin is higher than the distance between the two components, you will have initial penetrations.

I found that depending on Gapmin, penetration occurs.

 

Thanks
