Inquiry about Contact Interfaces 24/25 in OpenRadioss

[greazee]

Hello,

I am investigating the behavior of some contact interfaces in OpenRadioss and am particularly interested in understanding how the contact interfaces 24 and 25 are working. Is there are any references to articles, documentation, or discussions that might shed light on their functionality or provide insights into how these interfaces are handled in the code.

Thank you in advance for your help!
