I use the user subroutine "uel" in ABA/Standard to define added mass and damping due to hydro-dynamic effects. It works fine. The problem is with the contour plot. When I try to plot the stress contour, I always get an orthogonal cross at each structural node, which can not be turned off. They are really annoying. Does anybody know what those crosses are, and how to turn them off? Thanks in advance.
