PITTSBURGH, Dec. 20, 2013 /PRNewswire/ -- With faster
pre-processing, solver and optimization technologies, users of
ANSYS Inc.'s (NASDAQ: ANSS) release 15.0 for fluid dynamics
simulation will be able to meet tighter development deadlines and
further reduce time to market.

Released earlier this month, new functionalities in
ANSYS® 15.0 offer users a wealth of benefits across its
product portfolio. As the second in a series of announcements
highlighting improved capabilities across three main physics areas,
ANSYS today focuses on the enhancements to its computational fluid
dynamics (CFD) offerings at release 15.0. CFD solutions from ANSYS
provide the ability to confidently predict that products impacted
by flow phenomena will thrive in the real world. As products grow
increasingly complex, the geometry and physics being simulated are
also becoming more complicated. The advances in ANSYS 15.0's CFD
solutions make it easier for users to arrive at fast, accurate
solutions.
Thanks to smart optimization technologies, faster solver speed,
ground-breaking parallel scalability, intuitive geometry
functionality and parallel meshing technologies, users of ANSYS
15.0 for fluid dynamics will be able to design new products faster
and more accurately than ever before.
Release highlights for computational fluid dynamics in
ANSYS 15.0 include:
- Optimization is faster thanks to an improved adjoint solver.
The adjoint solver now supports larger problems with meshes up to
30 million cells. The core functionality of the adjoint energy
equation has been implemented in a way that observables can be
defined as various integrals of heat flux and temperature —
including averages and variances. As a result, the adjoint solver
can now be used in problems where heat exchange maximization or
heat loss reduction is a key design goal.
- ANSYS 15.0 provides numerous solver speed improvements. For
example, simulations of immiscible fluid using the volume-of-fluid
model are up to 36 percent faster. Transient Eulerian multiphase
flow simulations are also accelerated thanks to adaptive
time-stepping support. Dynamic combustion mechanism reduction can
lead to simulation up to seven times faster with large chemical
mechanisms.
- Simulation of fluid flow with heat transfer has been enhanced
in numerous ways in ANSYS 15.0 multi-layer shell conduction greatly
simplifies thermal management simulations and speeds up the overall
workflow, avoiding the need to volume-mesh very thin material
surfaces. Anisotropic thermal conductivity behavior for solid
materials can also now be modeled. The surface-to-surface radiation
model supports non-conformal meshes. This provides more flexibility
in meshing both large fluid volumes together with thin fabricated
structures, also helping to speed up the time to
solution.
- Continuous improvements in ANSYS 15.0 with high-performance
computing (HPC) scalability and robustness allow engineers to
increase simulation throughput. One set of benchmark results
demonstrated scalability above 80 percent efficiency with as few as
10,000 cells per compute core, representing a three-fold
improvement over previous releases. ANSYS 15.0 also reduces the
time needed to read a simulation file and start the simulation on
large HPC clusters, in some extreme cases going from 30 minutes to
30 seconds. Furthermore, a benchmark example of a flow
simulation with large number of particles showed 80 percent
parallel efficiency on 6,000 computing cores with ANSYS
Fluent®. Thanks to efforts to improve ANSYS
CFX® scalability on larger core counts, turbomachinery
and other applications are being sped up significantly. Also, GPUs
can be used with the AMG coupled pressure-based solver in ANSYS
Fluent, with benchmarks here showing a speed up of up to 2.5 times
is possible.
"Thanks to ANSYS fluid dynamics simulation solutions' speed and
unmatched scalability on high-performance computer clusters, we are
able to quickly and accurately assess the performance of a large
number of designs," said Rob Rowsell
of Wirth Research.
- Multiphysics simulations are easier to setup and run thanks to
the introduction of 2-way thermal and 2-way thermal with
force/displacement with ANSYS Fluent and ANSYS Mechanical via
system coupling. This solution fully automates simulations which
were previously extremely time consuming to setup and perform.
- Pre-processing complex CAD geometry is much faster, thanks to
the introduction of advanced diagnostic and repair tools that guide
the user when dealing with problematic geometries. Geometry
problems like holes and gaps are automatically detected and can be
quickly remedied with limited manual intervention. Major speed and
memory use improvements have been implemented for all meshing
methods. In addition, parallel meshing delivers dramatic
reductions in mesh generation time. For example, for a 42
million-cell mesh, meshing time is reduced by up to 7.4 times when
multiple processors are used.
