- Repair Geometry
  Review geometric errors in the model's surfaces and solids and fix any defects.
- Create Geometry
  Explore the tools used to create geometry.
- Edit Geometry
  Explore the tools used to edit geometry.
  - Split Surfaces and Solids
    Use the Split tools to create fixed points and split surfaces or solids using a variety of methods.
    - Split Interactive
      Use the Split: Interactive tool to quickly create fixed points on surfaces and edges, and split surfaces with lines. You can also remove fixed points from surfaces or surface edges to unsplit them.
    - Split with Nodes
      Use the Split: Nodes tool to split surfaces using ordered (node list/path) and non-ordered nodes selections.
    - Split with Lines
      Use the Split: Lines tool to split surfaces and solids using lines, bounding lines, offset lines, and graphical lines.
    - Split with Surfaces
      Use the Split: Surfaces tool to split surfaces and solids using surfaces.
    - Split with Planes
      Use the Split: Planes tool to split lines, surfaces, or solids.
    - Perform Parametric Trimming
      Use the Split: Parametric tool to break selected surfaces edges at multiple points.
    - Split by Curvature
      Split surfaces based on curvature or angle.
  - Stitch Surfaces and Suppress Edges
    Use the Stitch tool to stitch and unstitch adjacent or overlapping surfaces, and suppress or unsuppress edges.
  - Imprint Surfaces
    Use the Imprint tool to imprint points, nodes, lines, or surface onto target surfaces, thus creating new fixed points or edges.
  - Drag and Spin
    Use the Drag/Spin tool to push or pull surfaces and spin lines and surfaces in order to creates surfaces or solids.
  - Combine, Subtract, Intersect Solids
    Use the Boolean tool to combine solids, subtract one solid from another, and find the intersection out of the solids.
  - Disconnect Solids
    Separate solids that are connected at a shared interface.
  - Find and Fill Cavities
    Use the Plug tool to find and fill cavities. The Plug tool can also be used to remove protrusions, holes, and complex features.
  - Scale Parts
    Use the Scale tool to resize geometry in your model.
  - Mirror Entities
    Use the Mirror tool to mirror/reflect selected entities across a symmetry plane.
  - Fuse 2D Shell Meshes
    Use the Fuse tool to connect discrete topology surfaces/solids/parts. The Fuse tool can be utilized to connect close proximity inputs by defining a threshold.
  - Merge Solids or Surfaces
    Merge two or more solids or surfaces. Solids are merged by removing shared faces while surfaces are merged by suppressing shared edges.
- Geometry Cleanup
  Clean up problematic areas on geometry.
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.
Meshing
Generate surface/volume mesh by defining mesh controls, or interactively create and edit 2D surface mesh.
Solution
Define output conditions, run the simulation, and view the results.
