June 2008 - DDS Announces New Courses on
FEMtools Programming and Design Optimization
Following the release of the new FEMtools Optimization
product, Dynamic Design Solutions announces two new courses:
-
Introduction to Programming in FEMtools Script (1
Day)
The open architecture of FEMtools and the
powerful FEMtools Script language make it possible to approach
almost any optimization problem, even non-structural. To fully
exploit all capabilities, users should be trained in how to
implement their own function evaluations, use external solvers,
interface data, and produce custom reports.
This course is primarily intended for all who
want to exploit the potential of FEMtools Optimization by
implementing their own processes. It is also intended as
an introduction for customers who want to learn and use the
FEMtools script programming language and the FEMtools API function
library to develop their own tools, integrate in-house analysis and test
software or develop new applications.
-
Introduction to Design Optimization using FEMtools
(2 Days)
FEMtools Optimization is an advanced solution for
structural optimization featuring a function library for
constrained nonlinear optimization and ready-to-use commands to solve the
common structural optimization problems like size, shape,
topology and topometry optimization. This course provides an
overview of the theoretical concepts, implementation in FEMtools
and practical applications.
This course is primarily intended for all who
want to learn about using simulation-based optimization
techniques.
During all courses, the
FEMtools software will be extensively used for hands-on exercises during
approximately half of the time.
The current schedule for 2008 includes the following courses:

March 2008 - Hong Kong Highways
Orders FEMtools for Postprocessing Stonecutters Bridge
Monitoring Data
Dynamic Design Solutions announces that the Government of
the Hong Kong Special Administrative Region (HK-SAR) has
ordered FEMtools Framework
as the platform software to develop a custom monitoring
system for the prestigious Hong Kong Stonecutters
bridge. This is one of the longest cable-stayed
bridges in the world, currently under construction (http://www.stonecuttersbridge.net).
The custom monitoring system will be part of the bridge's
Wind and Structural Health Monitoring System (WASHMS) that
monitors the response of the bridge to wind loading,
temperature loading, highway loading and seismic loading.
Furthermore, several licenses of
FEMtools Model Updating
will be delivered to the onsite bridge control units for
real-time correlation of the bridge mode shapes with
reference modes obtained from a validated and updated finite
element model. The bridge mode shapes will be obtained
with ARTeMIS software (http://www.svibs.com)
using output-only modal analysis.
This order will be a major showcase for state-of-the-art
structural health monitoring technology
that uses operational modal testing and model updating-based
damage identification applied on large scale civil
engineering structures.

March 2008 - Announcing FEMtools Optimization
Dynamic Design Solutions announces FEMtools Optimization,
the newest member of its FEMtools family of products.
FEMtools Optimization is a toolbox for general purpose
and structural design optimization. In combination with
FEMtools Model Updating, it provides the unique possibility
to perform design optimization on validated and updated
finite element models.
Using a powerful non-linear optimizer, FEMtools can be
used for solving arbitrary single or multi-objective
non-linear optimization problems with a very large number of
variables. Combined with FEMtools internal sensitivity
computation, any type of optimization problem can be defined
by user-programmed cost functions and constraint functions.
For structural optimization using finite element analysis,
function re-analysis can make use of FEMtools'
internal solver capabilities or use drivers to pilot
external programs like Nastran, Ansys or Abaqus.
Ready-to-use commands are provided to solve the following
common structural optimization problems:
Size Optimization - For optimizing component parameters such as cross-section and thickness.
Shape Optimization - For optimizing the shape of existing components.
Topometry Optimization - Optimizing component parameters on an element-by-element basis.
Topology Optimization - Creating new designs with a layout optimized for a given load and manufacturing constraints.
The FEMtools
open architecture, combined with the FEMtools Scripting
language, provides virtually
unlimited flexibility in the problem definition and offers
function re-evaluation using your
preferred FE-solver on Windows, Linux and Unix OS.
FEMtools Optimization will first be released in Q2/2008 as a
separate FEMtools 3.3 product configuration, or in
combination with FEMtools
Model Updating.
Tools for design of experiments, response surface modeling, composite
materials optimization and probabilistic design improvement will be added in
subsequent releases.
For preliminary product information, see
FEMtools Optimization.

February 2006 - FEMtools Manuals
Available in Japanese Language
Software Express, Inc., FEMtools Solutions Partner in Japan,
announces the availability of FEMtools manuals in Japanese language.

December 2005 - Dynamic Design
Solutions Joins ABAQUS Inc. Partner Program
For the past several years, Dynamic Design Solutions has
developed a direct interface between FEMtools and the ABAQUS
advanced finite element analysis software with the support of
different ABAQUS distributors and customers. Dynamic Design
Solutions has now formally joined the new ABAQUS Inc. Partner
Program to further strengthen and extend the integration between
FEMtools and ABAQUS.
The ABAQUS translator is an optional component of FEMtools
Framework. It imports an ABAQUS input file and converts a complete
finite element model and associated properties into the FEMtools
database table structure. Other functions of the translator
are to import element mass and stiffness matrices, and shapes
resulting from static, modal or forced response analysis.
The ABAQUS finite element model and analysis results data
can be used by all FEMtools application modules for advanced
structural dynamics simulation, pretest planning, sensitivity
analysis, model updating, and design optimization. An updated
FE model, or an optimized design, can be exported and converted
by the ABAQUS translator into a ready-to-use input deck for
ABAQUS. This close integration between FEMtools and ABAQUS allows
to automate processes that require numerous restarts of the
ABAQUS solver like, for example, model updating, design of experiments,
and probabilistic analysis.
For more information on the benefits of the ABAQUS Partner
Program for FEMtools and ABAQUS users, please contact

November 2005 - Material Identification
using FEMtools and New Documents Available for Download
The finite element model updating method that is implemented
in FEMtools can be used for identifying the elastic properties
of isotropic, orthotropic and anisotropic materials.
If the material properties or beam section properties are
selected as global updating parameters, and the modes of vibration
of a test specimen (obtained by measurement) are used as reference
responses, then the updating procedure will iteratively adjust
starting values until predicted dynamic behavior corresponds
with observed one.
This approach is a non-destructive material testing method
that is especially useful for composites and laminated materials.
The method easily adapts to be used in temperature-controlled
environments to obtain properties as function of temperature
(or other controlled conditions).
Applications of this methodology can be found in the following
recent theses:

of the Elastic Properties of Layered Materials, Doctoral
thesis, Catholic University of Leuven, October 2005.

Simulating Dynamic
Response of Civil Engineering Structures
Model updating of civil engineering
FE models is a growing field. This is a result of the growing
popularity of output-only modal test technology which provides
usable reference data for model updating. There is also the
growing need for structural health monitoring solutions including
damage detection, damage identification and residual lifetime
estimation.
FEMtools can play an important
role in the integrated systems that will be required to make
this happen. To illustrate the potential, a number of new case
studies were added to the Solutions section of the FEMtools
website:
