Dear Baazouzi,

A "glued" interface in FLAC is an interface used to join two sub-grids but at which no slip or separation will occur.

Hope this helps.

Dear Fernanda.

Thank you for your answers. but i have a question

in the slope, i had overestimate of the results when i used the glued but in the horizontal ground surface it not influenced

best regards

Dear Baazouzi,

The code assigns high strength properties to the "glued" interface to prevent any slip or separation. If you want to simulate a real interface, you probably should not use a "glued" interface, because such interface is not supposed to influence the behaviour of the system to any great extent. It is just an artificial device to connect two sub-grids together.

Dear Fernanda.

Yes, i found the best results compared with litterateur when i used unglued
