Direct Transient Analysis

Direct Transient Analysis solves the coupled system of dynamic equilibrium equations. State-of-the-art numeric integration schemes and iteration methods are employed to achieve accurate and cost effective solutions for linear and nonlinear problems. Geometric and material nonlinearities can be considered. The features include:

• Implicit and explicit time integration schemes
• Consistent or lumped mass matrix
• Discrete damper elements and proportional (Rayleigh) damping Non-zero initial displacements and velocities, and moving boundary conditions
• Self-adaptive time steps for implicit and explicit scheme Geometric and material nonlinear behavior
• Moving frames of reference- centrifugal and Coriolis forces
