Hi to all, I’m new of this forum.
Till now I have used Navigator for simple structural modeling without difficulties, but now I’m trying to modelate a soil liquefaction problem with, but I meet many difficulties:
1) for example when I generate elements called “Brick8N_u_p_U” I discover that the correct code called “BrickUp” (that I belive to write) element is not written, instead there is in the .tcl file a thing like “Brick8NupU” that belongs to any element in the OpenSees library (I think). I can correct this by a simple find and replace element in .tcl file, but remains a problem.
2) How can I give pore pressure fixities to my nodes?
3) How can I switch material stage from elastic (gravity) to plastic (loading sequence)?
I hope to recive some help for my problem,
have a nice day,
