      - NX Reader
        NX import is available through two different readers: UGOpen native reader and a third-party non-native reader.
        NX Native Reader
        The NX reader utilizes the UGOpen library to read files from NX.
        NX Third Party Reader
        The NX Third Party reader does not need a valid NX installation or license to access these libraries.
      - OCX Reader
      - Parasolid Reader
      - Rhino Reader
      - SolidWorks Reader
      - STEP Reader
    - CAD Import Options
      CAD readers provide options for processing data during import.
    - CAD Import Message Files
      Each reader reads the CAD file and stores the geometry information. When a CAD file is read, a .msg file is created (or appended to) in the current working directory.
    - CAD Import Difficulties
      Learn about possible difficulties you may encounter during CAD import.
    - CAD Metadata Naming
      The metadata names generated by the CAD readers are composed of a general prefix followed by a metadata specific name. The prefix is specified using the @MetadataPrefix option in each _reader.ini file.
  - Solver Deck Import
    Import FE models for supported solver interfaces.
  - Results Import
    Use reader options to control the behavior of the code when reading results from disk.
- Save Files
  Save all of the data in your current session.
- Export Files
  Export FE data in your current session.
- Take a Screen Capture
  Record a video or take a snapshot of the screen.
- Import and Export Templates
  Quickly import and export templates containing full simulation settings, part definitions, or mesh controls.
- Extensions
  Extensions are programs integrated with the application to enhance or extend the user experience.
Convert
Use the Convert tool to convert entire models between data types.
Geometry Repair
Manage CAD, FE, and 2D parametric sketch geometry.
Meshing
Generate surface/volume mesh by defining mesh controls, or interactively create and edit 2D surface mesh.
Setup
Prepare your model and run the simulation.
Post-Processing
Post-process the simulation results by creating visualizations and measurements.
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.
Automation
Automate simulation processes with templates and utility scripts.
Solver Help
More resources for AcuSolve and ultraFluidX solvers.

NX Reader

NX import is available through two different readers: UGOpen native reader and a third-party non-native reader.

From the Geometry Import Options dialog, you can choose between two reader options when importing NX files, giving you greater flexibility.
