Topic: GAP vs contact volumes

Hi all,

For modelling a 3D GAP interface (mohr-coulomb) in GID, should i use the contact volume elements and subsequently assign the interface material model? Or should i use the conditions->GAP load for volume? and whats the difference?

The goal is to model an interface similar to the GAP interface in Eng 2D.

Thanks in advance!

Re: GAP vs contact volumes

Dear laurens,
yes, Contact Volume is what you need, please see ATENA-GiD User's, 5.3.6 Interface Material for basic related information.
The Condition Initial GAP Load for Volume can be used to define an initial opening of a Contact Volume.
