Create, open, import, and save models.
Import Files
Import an existing file to the current session.
CAD Import
Learn about the supported CAD readers and the options available for importing CAD geometry data.
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.

  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 Modeling
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.
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.

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.

For example, the file iges_reader.msg is created for the IGES reader.

Three types of messages appear in the .msg file.

Info: Includes information about the file being read.
Warning: Indicates that data was modified.
Error: Indicates when a geometric entity could not be created.

These files can be useful for debugging errors found during import.

For CATIA and JT formats, those files (respectively ct_raedr.msg and jt_reader.msg) will contain detailed information about imported assembly files.
