Setup
Prepare your model and run the simulation.
- General Setup
  Prepare your model for a general AcuSolve simulation.
- Aerodynamic and Aeroacoustic Setup
  Prepare your model for wind tunnel analysis using ultraFluidX.
  - Transfer Data
    After preparing your model, use the Data Transfer tool to transfer mesh data to the environment used for aerodynamic and aeroacoustic setup.
  - Parts and Assemblies
    Manage the parts and assemblies that make up your model.
    - Assemblies Overview
      An assembly is a list of parts and sub-assemblies that organizes your model hierarchically to reflect the data structure of the modeled product.
    - Parts Overview
      A part is a geometric object made up of shell elements. Parts can be grouped together into assemblies and sub-assemblies, so that you can organize your model hierarchically.
    - Create Assemblies
      Create an assembly and add parts to it in the Model Browser.
    - Edit Parts and Assemblies
      Edit the name, color, visibility, and associated properties of parts and assemblies using the Property Editor. Rename and delete parts and assemblies.
    - Define Faceting Parameters
      Each geometry part has a Faceting property.
  - Prepare the Model
    Set up the wind tunnel and prepare the aerodynamics and parameters of your model.
  - Analysis
    Submit jobs and view reports.
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
More resources for AcuSolve and ultraFluidX solvers.

Create Assemblies

Create an assembly and add parts to it in the Model Browser.

Do one of the following:
- Right-click on an assembly in the Model Browser.
- Right-click in empty space in the modeling window.
From the context menu, select New Assembly.
Enter a name for the new assembly.
Names can be any length. The only restrictions on the characters you can use in a name come from your intended use of the model after you export it. If you intend to export your model to other applications, you should follow any restrictions that software may have for object names. Typically, the following characters should be avoided: " ' * ? $.
Press Enter.
Drag parts or other assemblies onto the target assembly.

Tip:

To copy a part into an assembly rather than moving it, hold down Ctrl while dragging-and-dropping.
Parts and sub-assemblies within an assembly are positioned in space relative to the parent assembly. If you translate or rotate a parent assembly in the modeling window, its parts and sub-assemblies move with it.
Assemblies do not have their own color, visibility, or material properties. Changing any of these properties for an assembly actually applies the change to the individual parts within the assembly down to the lowest level in the hierarchy.
