ESI Group has released CFD-ACE+ V2009.0, which strengthens the modular and expandable design of the computational fluid dynamics (CFD) and multiphysics software.

ESI Group’s CFD-ACE+ enables coupled simulations of fluid, thermal, chemical, biological, electrical and mechanical phenomena for a variety of applications across a range of industries.

There are over 30 additions and improvements in the V2009.0 release.

CFD-ACE+ V2009.0 has focused on the market’s demands for reducing costs.

CPU costs of transient simulations can be reduced using fast time stepping (FTS), by ensuring convergence of each time step within a few iterations.

FTS was first implemented in V2008.2 and has now been improved to allow for auto time stepping.

It has been extended to support additional modules including porous media, deforming grids and free surfaces (VOF).

A major highlight of CFD-ACE+ V2009.0 is the improvement of the two-phase module with a numerical formulation that is more robust and faster to converge.

In addition, two-phase coupling allows the most accurate modelling of two-phase simulations in porous media regions.

This improvement enhances ESI Group’s capabilities for Proton Exchange Membrane Fuel Cell (PEMFC) modelling and helps address common deficiencies of previous model formulations.

This is a significant advancement for the simulation of fuel cell water management.

Additionally, a large number of processes and applications can now be addressed using the enhanced two-fluid model.

Advanced front methodology for unstructured triangular surface meshing in CFD-GEOM V2009.0 also includes advances in accuracy of the CFD-ACE+ solver and the mesh generation capabilities in CFD-GEOM.

The general purpose mesh generation tool CFD-GEOM has added advancing front surface triangulation to its set of surface meshing tools.

Users can now select from Delaunay triangles, advancing front triangles, quad morphing, or quad paving algorithms.

ESI Group wants to give to users the ability to select the best surface mesh type for the specific application.

Other CFD-GEOM improvements include remeshing of discrete surfaces and boundary layer generation from discrete surfaces, which make working with existing (legacy or third party) meshes easy.

CFD-ACE+ V2009.0 also offers an ESI CFD mobile support, providing remote access to CFD-ACE+ core applications (CFD view and CFD GUI).

ESI CFD mobile allows engineers and managers to have hand-held access to post-process solutions remotely from an Iphone or Ipod Touch.
