Project Arro is an Invitation Only Technology Preview. This is not our normal public technology preview because the simulation team is interested in working exclusively with existing Autodesk Simulation users. Project Arro is designed to enable Autodesk Simulation Mechanical, Autodesk Simulation CFD, and Autodesk Moldflow users to rapidly simplify and prepare CAD for simulation. Project Arro reads in native CAD geometry and neutral files, allows you to modify them with many built in direct modeling tools, and then writes out simulation-ready CAD files that can be more easily and efficiently meshed.
Originally, the project got its name from an acronym:
A = Analyze geometry
Check model integrity (slivers, problematic edges, overlapping faces, interferences, etc.) Detect and categorize features (holes, fillets, chamfers, embossed or raised features, etc.)
R = Repair problems
Option to "auto-heal" identified issues based on a given tolerance or criteria Split faces or stitch surfaces
R = Remove unnecessary features
Rapid selection and defeaturing without affecting source CAD Associative simplifications (future)
O = Optimize designs
Directly edit geometry with simple push/pull/modify commands to explore ‘what if’ scenarios Create alternatives that can be quickly and easily simulated using associative updates
Now it's really a rolling showcase for SimStudio, so customer feedback can shape its development. The other day the team supplied me with a new build to post to the Autodesk Labs project. Senior Software Quality Assurance Engineer, Hugh Henderson, shared what was in the new build. Based on participant feedback so far:
- Adaptive mesh refinement control for LSS studies (solution convergence)
- Per-body local mesh control support for solids and shells
- Latest versions of CAD files can be opened (e.g., Inventor beta)
- Maximum face pair distance control for Midsurface shells
- Explicit studies result output types can be specified in the study settings
- Reaction Force result type is added to Explicit studies
If you are an Autodesk Simulation user and wish to join this project, you can request participation.
Meshing around is alive in the lab.
