Setup
Prepare your model and run the simulation.
- General Setup
  Prepare your model for a general AcuSolve simulation.
  - Flow
    Set up the simulation model, materials, domains, and boundaries.
  - Radiation
    Define radiation conditions and create emissivity models.
  - Motion
    Define direct, derived, and constrained mesh motion.
    - Set Up Mesh Motion
      Use the Settings tool to define the mesh motion equation to be solved.
    - Direct Motion
      Define explicit motion or motion sources on solids or surfaces.
    - Derived Motion
      Define how to interpolate the effect of the motion created with the Direct tools.
      - Define Interpolated Motion
        Use the Interpolated tool to interpolate direct mesh movement onto surrounding solids/surfaces and update the mesh accordingly.
      - Define External Surface Motion
        Use the External Surface tool to specify a fluid surface that interacts with a solid/structural surface from an external code in order to solve Direct Coupling Fluid Structure Interaction (DC-FSI) problems.
    - Constraints
      Define how the nodes will move around certain surfaces.
  - Solution
    Define output conditions, run the simulation, and view the results.
  - 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
More resources for AcuSolve and ultraFluidX solvers.

Derived Motion

Define how to interpolate the effect of the motion created with the Direct tools.
