WebbUsing this card the initial stress and strain (Normal stress, Shear stress and plastic strain) can be defined on solid elements. These normal stresses are in X, Y, Z … WebbA: It's tricky and often iterative to attain efficient convergence because the convergence of an explicit dynamic relaxation solution is affected by not only ramp time of the load, but also time step size and the natural frequency of the system being modeled.
