Time average is an output type which is available in both Analyst and Designer Mode. Time averages calculate the time-varying sum and average of the nodal elements requested. Time averages can be calculated for six data array types:

  • Acoustic Pressure
  • Displacement 
  • Velocity 
  • Stress
  • Strain 
  • Force

Designer Mode

Time averages can be found in the Model Tree in Designer Mode at Model > Outputs.
