Loads and Result Options for Dynamic Analysis

Loads

Modal Time History Analysis
  • Time-varying force and pressure
  • Time-varying remote loads or remote mass.
  • Initial conditions defined as a finite acceleration, velocity or displacement at time t =0
  • Uniform and selected base excitation defined as time-varying acceleration, velocity or displacement
Harmonic Analysis
  • Peak amplitudes of force and pressure versus frequency
  • Frequency-dependent remote loads or remote mass
  • Uniform and selected base excitation defined as peak amplitudes of acceleration, velocity or displacement versus frequency
Random Vibration Analysis
  • Power spectral density (psd) curves of force and pressure
  • Frequency-dependent remote loads or remote mass
  • Uniform and selected base excitation defined as psd of acceleration, velocity or displacement
Response Spectrum Analysis
  • Uniform and selected base excitation defined as peak amplitudes of acceleration, velocity or displacement versus frequency

Result Options

  • Contour plots of displacements, accelerations, velocities, stresses, strains for a specified solution step, or extreme values across all solution steps.
  • Response graphs of displacement, velocities, and acceleration at specified locations. For random vibrations, you can plot rms values for the whole frequency range or psd versus frequency.
  • Response graphs at the center of gravity of a body that is treated as a remote mass, or at a point where you apply a remote load or remote mass.
  • Listing displacements, accelerations, velocities, stresses, strains, and reaction forces.
