January 1, 2005, Mountain View, CA: ACUSIM Software, Inc. today announced that version 1.6 of its flagship computational fluid dynamics solver is now available. Release v1.6 adds increased functionality while still delivering to customers the robustness, speed and accuracy that is the hallmark of the AcuSolve software. Significant new v1.6 functionality (over v1.5) includes:

• Enhanced Arbitrary Lagrangian-Eulerian (ALE) mesh movement through user controlled action
• Rigid Body Dynamic coupling with fluid flow solution
• A practical Fluid-Structure Interaction (FSI) capability that allows for bi-directional coupling of deformable solid and fluid flow
• A new Surface-Surface Interface (SSI) algorithm which enables
  • “Tied” (non-conformal) interfaces between dissimilar materials (e.g. fluid-solid regions in contact), and mesh elements (e.g. tetrahedral to hexahedral element mesh)
  • Fully arbitrary sliding mesh between rotating/stationary or rotating/rotating machinery components
• A pseudo-compressibility functionality to enable noise generation calculations
• Extended functionality of non-newtonian fluid flow calculations through incorporation of additional physical models
• Numerous output data commands to facilitate increased comparison to experimental data
• Full support for serial and parallel execution on 64bit Linux operating systems
• Enhanced client-server computing capability to facilitate coupling of AcuSolve to 1-D systems analysis (e.g. control ) software
• A new solver GUI, AcuProbe that allows for engineering quantities of interest (pressure drop, wall heat flux, drag, etc…) to be monitored while the solver is still running.

"AcuSolve v1.6 continues to improve on its predecessor, v1.5.," said Farzin Shakib, President of ACUSIM Software Inc. “We have increased the simulation capability of the software through introduction of general mesh movement to include coupling with rigid body dynamics, sliding meshes and a practical FSI where a structure moves under the forces of the local fluid flow.” "We look forward to working with our new and potential customers to help them achieve increased return on investment through utilization of our fluid dynamics simulation software," noted Steve Cosgrove, VP Technical Sales and Support. The software is available for immediate release. Please contact your distributor or ACUSIM software.
