Joanna	Hi, Is it possible to apply a FRICTION DATA FILE in 3D? The 3D-dico can't seem to find the keyword. Thanks in advance! Joanna

Hello,

Alas this is not programmed in 3D. If you do not have different friction laws, just different zones, and if you have already done the data file, a possibility would be to do one time step in 2D, asking for the friction coefficient in the results file (W in the list of VARIABLES FOR GRAPHIC PRINTOUTS). Then you can use this results file as a geometry file for the 3D calculation, and friction will be recognized (hopefully...).

With best regards,

Jean-Michel Hervouet

huyquangtran OFFLINE Expert Boarder Posts: 271 Thank you received: 23	Sorry I have made it done! I would like to say that we can apply bottom friction locally in 3D model!
