The team at the Autodesk Media Summit 2012 worked quite hard to show how Autodesk has poured their energies into the Simulation platforms. Autodesk Simulation CFD seems to have received the lion’s share to the attention this time around.

Luke Mihelcic, Autodesk Simulation CFD product marketing manager, describes how this year’s enhancements make Simulation CFD fast, accurate, flexible


Autodesk Simulation CFDThe most notable was speed. CFD team reports that they are seeing increased solving rates since Blueridge Numerics was acquired by Autodesk about a year ago. 34X faster with their HPC accelerant solver. Solutions that took weeks, now take hours.

Additional performance increases include:

  • 2X faster Hyper-threaded meshing
  • 26X faster Radiation clustering results


Autodesk Simulation CFDMesh history manager captures meshing changes in order to help users make better decisions as they iterate through refinements.

Adaptive meshing automatically and intelligently adjusts meshing based on the physics in your model, detecting key factors such as high and low velocity regions in the fluid. A check box was added for the option, and a field is available to specify the number of refinement iterations.


Autodesk has improved model information transfer between it’s engineering products, as well as some usability considerations. Fusion continues to dominate as the interoperable partner tool with simulation products, with improved interoperability and tool enhancements:

  • The ribbon interface has been made consistent across all Simulation products, as well as Fusion, and Inventor.
  • Associated model connection between Fusion and Simulation CFD
  • Some of Fusion’s simplification tools have been added directly to the CFD ribbon.
  • Volume calculation tools are now available in Fusion and remain associative. Improved tools make setup simpler and much faster
  • Materials from Fusion and Inventor transfer properly through to CFD model

Autodesk Simulation CFD(The Materials transfer was likely only possible after the new global improvements in the Autodesk Materials library.)

Additional improvements include:

  • Simulation CFD has been added to the Autodesk Wiki help system.
  • Additional CAD models can be opened directly, including Catia and ProE.
  • Really cool Revit model transfer has been made associative as well

Showcase Overlay now permits Simulation CFD to overlay it’s results on photo-realistic images through Showcase. This is a sweet enhancement that will allow more people to convey key results from analyses to a wider audience. I’m definitely going to check this out first hand.

Keep checking back for simulation simulation information as well as the rest of the Autodesk product lineup for 2013.
