Product of the Month: September 2015

CD-adapco, Melville, NY, has released STAR-CCM+® v10.04 simulation software that features a new finite element-based Solid Stress Solver, enabling both computational solid mechanics and computational fluid dynamics from a single, integrated environment. The new release also includes the Adjoint Solver for Coupled Solid Energy, enabling sensitivity analysis of solid conduction problems. This solver can be used in conjunction with the adjoint flow solver for performing sensitivity analysis and optimization for problems involving conjugate heat transfer. Reference geometry transfer through the STAR-CAD client allows the user to pass more data from their CAD package to STAR-CCM+, including transfer coordinate systems and reference planes, and these are automatically synchronized during updates.
