July 2011/ -- SC/Tetra V9,
Cradle’s flagship unstructured mesh computational fluid dynamics (CFD) software,
has been released with powerful new features that enable Cradle users to set-up,
solve, and post process CFD simulations faster than ever.
SC/Tetra V9 has progressed to a new
stage of simplification since its inception in 1998 when the vision of making
CFD in integral tool of the daily engineering process was conceived.
Introduction of one of the industry’s first auto mesh generators, a boundary
condition wizard, highly efficient solver, and powerful physical models have all
advanced this objective.
SC/TetraV9 offers a new level of
capabilities.
-
*Meshing enhancements speed most grid generation
functions by nearly a factor of two and surface wrapping by a factor of four.
-
*A parallel computing edition efficiently
allocates process computations to each core to maximize computational speed.
-
-
*Combining the free surface method and overset
mesh enables simulation of a dynamical moving object such as an object falling
into a liquid or stirring of a liquid where the rotating blades break the free
surface.
-
-
*An optional function seamlessly couples SC/Tetra
with Abaqus enabling simulation of transient fluid/structure interactions.
-
-
* The full cavitation model more accurately
models the physics in the low pressure regions where steep density gradients
occur. This includes formation and transport of vapor bubbles and
consideration of the amount of noncondensible gases which are dissolved or
ingested in the operating fluid.
-
-
*A boundary layer transition turbulence model
simulates the highly complex transition from a laminar to turbulent boundary
layer.
-
-
* A solidification/melting model accounts for
both the latent heat from the phase change in the solid and the heat transfer
from the moving liquid phase.
-
-
* An enhanced human body thermoregulation model
simulates changes in metabolic state e.g. when the body goes from an active to
resting state. This is an important consideration for transient analyses.
-
-
* Improved mesh quality and 25% speed increase
when generating the prism layer along solid boundaries
SC/Tetra V9 has many
more enhancements than can be listed here. These improvements continue to
confirm Cradle’s strength in providing full general purpose CFD software that is
built for real world engineering challenges. |
