I am trying to model the abutment of a bridge having counterfort walls and piles as well. The meshing of the base slab has become very complex since of both the walls and the piles are connected to the base slab. I have used surface element for modeling the counterforts. For application of load I used hydrostatic pressure for the walls which is supposed to linearly interpolate but, it does'nt seem to be working when I am using triangular mesh option for walls. Plus, I am having a lot of errors to deal with. I have attached my model here.(Please visit the site to view this file)
