Exa Releases PowerDELTA for CFD
 BURLINGTON,
MA, Jun 26, 2009 - Exa Corporation, a global innovator of fluids simulation
(CAE/CFD) software for product engineering, announces the release of
PowerDELTA, the latest product in its suite of integrated tools that enhance
the product development process. PowerDELTA dramatically streamlines and
automates the simulation model creation process by enabling the numerous,
often lengthy, meshing tasks to be performed in a single, easy-to-use,
integrated application. Native CAD data of varying levels of complexity or
completeness are rapidly and easily transformed using a sequence of
parametric geometry and meshing features into high quality, simulation-ready
meshes. With PowerDELTA, design changes are rapidly propagated through the
simulation model to generate updated meshes — a huge, time saving, benefit.
“With the tough economic conditions leading organizations are seeking
even more urgently to reduce cost and accelerate time-to-market by
front-loading product performance analysis in the design process where
critical and costly design decisions are made,” remarked Stephen Remondi,
President and CEO at Exa. “An accurate and efficient analysis process
becomes essential because many design iterations will need to be analyzed.”
A key activity within the analysis process is preparing models for
simulation, and in most organizations it’s a significant barrier to an
efficient process. Typically, mesh preparation time is very long – taking
days or even weeks – and is complicated by the need to handle conceptual
geometry and poor quality carry-over CAD data. Further adding to process
inefficiency is the fact that many companies build multiple redundant
simulation models for different types of analysis. Worse still, it is
typical for a simulation model to be one-time, one-use only; due the extreme
difficulty traditional tools have updating simulation models when designs
change.
“PowerDELTA is a key component of Exa’s strategy to support the complete
digital product engineering and analysis process in real-world conditions,”
comments Dr. Paul Stewart, Exa’s Director of Product Management. “PowerDELTA
solves the problem by applying the proven concepts of parametric feature
modeling and history tree model management to the process of simulation
model creation and update.” Stewart continues, “PowerDELTA imports CAD data
from all major systems, handles varying levels of quality, provides an
environment for collaboration and team design, and enables change on any
level.”
About PowerDELTA
Exa’s latest product offers numerous benefits to enhance the simulation
model creation process:
- Reduces mesh preparation time - PowerDELTA is a single,
integrated, product that starts with input CAD and produces
simulation-ready surface meshes eliminating the multiple mesh
preparation tools and variety of data formats typically required.
Because PowerFLOW’s unique approach to analysis does not need a separate
mesh for the fluid, which is required with traditional fluids solvers,
once the surface meshes are created with PowerDELTA, the model is ready
for simulation.
- Highly productive - Designed for the professional user,
PowerDELTA has easy-to-use graphical interfaces that guide the user
through the feature creation process. Unique project, frame, and branch
data organization capabilities enable large models to be quickly sorted
and allow large mesh preparation tasks to be shared by multiple people.
professional user, PowerDELTA has easy-to-use the feature creation
process. High speed, high quality, wrapping and decimation features
allow high quality meshes to be created in significantly less time.
- Enables rapid response to design changes. Parametric feature
history tree regeneration allows the user to simply change feature
parameters and regenerate to propagate changes through the model.
- Handles design data of varying quality and size. PowerDELTA
can directly import and heal most CAD formats, removing the reliance on,
and wait for, the design department to export geometry in a neutral
format. PowerDELTA directly reads and retains native CAD assembly
structures eliminating the time-intensive task of recreating vehicle
sub-system structures.
- Eliminates redundant simulation model building. Typical
industry practice is to use different simulation tools for aerodynamic,
aeroacoustic, and thermal analyses – each of which require a separate
surface mesh and fluid mesh. Exa’s unique approach and focus on
validation of results mean that a single tool can be used for all types
of fluids-driven analysis. A single PowerDELTA mesh can be used with
PowerFLOW for aerodynamic, aeroacoustic, and thermal analyses.
- Enables reuse, captures best practice, & reduces errors.
Saved frames and branches with pre-built feature sequences easily
capture and allow reuse of best practices for different components of
the model, e.g. engine vs. upper body. PowerDELTA’s ability to read
native CAD assembly structures eliminates the typical errors of missing
parts from the simulation or using an incorrect configuration, thus
avoiding inaccurate results and wasted simulation runs.
