Hi All,
I am studying the seismic response of a structure with soil structure interaction in Plaxis 3D About the dynamics boundary conditions I know that free field are probably the best way to reproduce the lateral soil, obviously ensuring a certain distance between the structure and the borders. My doubt concerns the Deformations Boundary conditions (in the Model Explorer), by default these are fixed in "normally fixed". Should I also set these conditions as "free"? Or in a dynamic phase the "deformations boundaries" are ignored and only the "dynamics boundaries" are considered?Thank you
Dear Fausto,
If in a Dynamics analysis the Dynamics boundaries are activated, the Deformation boundaries are automatically ignored.With kind regards,
Dennis Waterman
