    - 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.
      - Define Part-Based Initial Conditions
        Use the Part tool to define initial conditions on all nodes (boundary + volume nodes) of selected solids.
      - Define Surface-Based Initial Conditions
        Use the Surface tool to define initial conditions on all nodes of selected surfaces.
      - Define Nodal Initial Conditions by Zones
        Use the Zones tool to define initial condition on all nodes enclosed within defined zones. You can define boxes, spheres, and cylinders as zones.
      - Define Nodal Initial Conditions by Plane
        Use the Plane tool to select solids and define initial conditions on either 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
More resources for AcuSolve and ultraFluidX solvers.

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.

Note:

Global nodal initial conditions can be defined in the Launch AcuSolve dialog under the Default initial condition section. If local initial conditions are applied, they will take precedence over default initial conditions.
Conflict resolution of selection will happen in Part and Surface based initial conditions.
You can define precedence on defined conditions in case of conflict. Lower precedence integers will be enforced.
