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.
A user can add a time average output to their model by following these steps:
- Select the plus icon to add an output
- Setting the Output Type to Time Average
- Choose which Data Array to average via the drop down menu
- Specify the region being averaged
Analyst Mode
Time averages are created in Analyst using the calc avrg command:
calc
avrg av1 aprs * regn $i1 $i2 $j2 $j2 /* calculates average acoustic pressure in specified region and outputs as av1
