Hi @csuznxg
I have to be honest, I am not familiar with this type of analysis and don’t know how much I will be of help. I may be able to help conceptually though, but I’m a little confused at differences in the boundary conditions and what your issue is exactly.
What do you want your constraints to be and what are your issues with implementing it?
I am so sorry that I didn't make myself clear. I made a simulation about slope blasting to shed light on the issue.
First, the implicit solution for initial geo-stress. Then goes to the explicit solution, and the initial geo-stress is transferred by "dynain" file.
As the picture shows, the left, bottom and right side of the model are applied translational constraint and non-reflecting boundaries. The surface of the slope is defined with free surface. In the explicit results, blasting has not reached the data collection point yet, but the velocity and stress of the point are changing from the beginning of the explicit solution.
How to maintain the initial stress effectively in an explicit solution and make it stable before the blasting stress distribution?
