Hi All,

 

I want to create 2 solid blocks touching each other and bolted together. I meshed them and when I import the same in Hypercrash and checked for intersections, it shows me an intersection.

I have tried to resolve this by Remove intersections option or 3D mesh editing, but could not remove this intersection.

 

Can you please help me how to remove such intersections and corresponding penetration.

Thanks in advance.

 

 Regards

Hi,

 

clearing intersection in this model should be easy- just translate one of the components in z-direction so there is a small gap, that is required for contact type 2 (tied) and 7 (general).

If no physical gap is required then go for type 20 contact.

 

Share the model if the issue persists.

Hi @Ivan

 

I cant move the component in z direction. As I wanted to simulate them with touch condition (gap in z direction is 0). 

Moreover entire geometry consist of more than 35 parts which will be a big task to align all of them again.

I am having same problem with almost all the parts.

 

I have also tried to give Type 20 contact but interference is still there.

May you please share the recommended parameters for Type 20 contact  for Crash Application.

 

Regards

Hi,

Make sure that both contact face nodes are in same plane as per CAD data.

This can avoid intersection if meshing is not checked activating CAD in wire frame mode.
