New Contact Types

[Anonymous]

Where can I find an explanation or tutorial of all the new contact types?

In my simulations, I have been using many contacts that are "separation no sliding" and "sliding no separation". What is the equivalent of these contacts in the new contact options?

Hi @Anonymous,

Glad to hear you're exploring the new simulation capabilities with Fusion 360! In previous versions there was "Separation, no sliding" is "rough contact" , and "Sliding, no Separation" is now "Sliding" contact.

Regards,

Andrew

Can you provide a explanation of each new contact type and compare them to the previous contact types? Previously we had "separation + sliding"; what is the equivalent now?

Seperation=?

Sliding=?

Rough=?

Offset Bonded=?

Hi @Anonymous,

You can read more about the contacts in the Fusion 360 help documentation. It will also give you some details on some of the parameters that available now!

Best Regards,

Andrew

Is there any place I can find more information regarding the 'advanced options' in the edit contact dialog box?

What are the units of these options? What are the units of the 'stiffness factor' option?

What are the default values if I don't fill these options in?

Hi @Anonymous,

These are some of the parameters available for the Nastran BSCONP card. The only parameter that I could anticipating needing to change would be the Stiffness Factor, which is used to determine the stiff value used during the penalty method for surface contact. When you have two materials that are highly dissimilar in stiffness like rubber and steel, the automatic value may be overly stiff or under stiff. The default value is 1, and can be set to a real value greater than 0.0; which is then used as a direct multiplier of the stiffness. Aside from this stiffness parameter, the others used very infrequently, and are not something that I would anticipate needing to use in the course of a typical analysis.
