Mohammed Yousif Fattah

Dear Ahmed

You don't have to introduce an interface at the vertical and horizontal part of the boundary. Interfaces are introduces between materials of different stiffness.

Ahmed Hussein Olat

Thank you Mr. Mohammed. In plaxis when doing dynamic analysis or liquefaction it is advised to do analysis in

1. Ko

2. phase 1 with DIFFERENT SOIL characteristics and

Phase 3 the dynamaic analysis with the UBC3D model

how do you go about this?
