Engineering Workspace Setup

This chapter covers the simulation capabilities of the flow solver, how the engineering module is organized in the user interface, performance characteristics, and where to find help.

Simulation Capabilities

The current production workflow supports:

Fluid Flow

• Incompressible Navier–Stokes
• Laminar and weakly turbulent regimes
• A fluid material library: Air, Water, Blood, Cerebrospinal, Urine
• Time-evolving simulations (the solver is intrinsically transient)

Scalar Transport

• Advection–Diffusion–Reaction for species concentration and passive scalars

Turbulence

The standard chatbot- and UI-driven workflow exposes the above. Fluid–structure interaction, conjugate heat transfer with deformable solids, and user-defined Python physics are not part of the standard offering.

User Interface Navigation

The Engineering module is organized hierarchically in the ActionsTree:

Project
└── Version (version_0, version_1, …)
    ├── Geometries      ← primary geometry + implanted devices
    ├── Materials
    ├── Boundaries      ← boundary conditions; zones attach here
    ├── Conditions      ← domain-wide conditions (gravity, fan, obstacle, …)
    ├── Centerlines
    └── Simulations
        └── job_0, job_1, …

Each container shows its item count, for example Boundaries (3).

Zones do not appear in the tree. They are managed from the Zoning tools group in the viewer toolbar — see Defining Zones.

Performance and Scalability

Solver features:

• Execution: on GPU by default. Runs that include an implanted device switch automatically to CPU execution.
• Scalability: Handle geometries from simple tubes to complex vascular networks
• Real-Time Updates: WebSocket communication provides live simulation progress
• Cloud Ready: Simulations can run on local machines or cloud infrastructure

Getting Help

Throughout the Engineering Workflow:

• Hover over UI elements for tooltips
• Open the tutorials panel with Show me the tutorial in the chatbot shortcut bar
• Review validation messages for configuration errors
• Contact support for complex simulation setup

Tip: Start with a simple geometry and known boundary conditions to familiarize yourself with the workflow before tackling complex simulations.
