      - Define Time History Output
        Use the Probe tool to monitor time history data on defined points at specific time intervals.
      - Define Surface Monitors
        Surface monitors for all defined boundaries are created automatically. However, additional surface monitors can be created using the Surfaces tool.
      - Define Volume Monitors
        Volume monitors for all defined domains are created automatically. However, additional volume monitors can be created using the Volumes tool.
    - Outputs
      Define nodal output for the entire model.
    - Nodal Initial Conditions
      Define nodal initial conditions for the simulation. You can define nodal initial conditions on the nodes of selected surfaces and solids, nodes within zones, and nodes of solids on the side of a plane.
    - Simulation
      Run AcuSolve, track solver and meshing jobs, and plot run time data.
  - AcuTrace
    AcuTrace is particle tracer that runs as a post-processor to AcuSolve.
- Aerodynamic and Aeroacoustic Setup
  Prepare your model for wind tunnel analysis using ultraFluidX.
Post-Processing
Post-process the simulation results by creating visualizations and measurements.
Automation
Automate simulation processes with templates and utility scripts.
Design Exploration
Once the baseline model is prepared, you can define morph volumes, morph geometry, create design shapes and run DOE studies. These tool work for both AcuSolve and ultraFluidX-based workflows.
Solver Help

Define Volume Monitors

Volume monitors for all defined domains are created automatically. However, additional volume monitors can be created using the Volumes tool.

From the Solution ribbon, click the Volumes tool.

Figure 1.
Select solids.
In the dialog, define the output frequency and/or output time interval at which results are extracted.
From the guide bar, execute the command in the following ways:
- Click to confirm your selection and remain in the tool.
  This allows you to continue creating instances and helps you visualize and edit instances with the legend.
- Click to confirm your selection and exit the tool.

Element Output

The options in the Volumes tool specify the output of the average of quantities integrated through the volume. The averaged quantities are output to the disk. By default, AcuSolve writes out this output at the last time step of the simulation.

Integrated output frequency: Specifies time frequency at which to output averaged element quantities. If zero, this option is ignored.
Integrated output time interval: Specifies time step frequency at which to output averaged element quantities. If zero, this option is ignored.
