One-Way and Two-Way Contact Definitions

This post will give you a brief summary of one-way and two-way contact definitions. The one-way/two-way refers to the treatment of slave nodes impacting the master segments. One-Way Contacts One-way was one of the first implementations in contact treatment and was done so such that it is computationally efficient. In the one-way contact treatment, the…

Automatic Timestep Control for Implicit Simulations

The known advantage with implicit simulations is that the solution is unconditionally stable allowing larger values of timestep. In implicit static simulations (IMASS=0 in *CONTROL_IMPLICIT_DYNAMICS), the simulation time has no real significance but is rather an indication of the applied load magnitude. For example if we have a simulation where a load is applied linearly…
