Dynamic Boundaries

[muhammedfurkanyilmaz]

Dear @KratosMultiphysics/geomechanics,
I'm trying to make a site response analysis to capture the response of a soil deposit. First I created a 2D3N diff. order line load condition and then apply the acceleration history at the bottom of the model using this condition. (But I'm not sure it's the right way to create such a loading in Kratos.) Moreover, when I constrained the model vertically at the bottom and side the solution was not converged. However, when I add a stage before the dynamic loading stage the solution is converging but the model is not displacing at the lower boundary, and no expected results are showing up. I've two questions
i) is there any dynamic boundary in Kratos like Tied degrees of Freedom, Freefield, etc?
ii) is the way I mentioned for loading right, if not can you kindly provide me an example file for such an analysis?
I'll appreciate any help you provide.
