The INTEGRATED Advantage: Overview
Company Commitment
Founded in 1984, INTEGRATED has been a developer of leading edge simulation software. INTEGRATED introduced
the first commercial boundary element (BEM) software on the PC environment for solving static electrical
and magnetic 2D fields. This was followed by 3D static electric and magnetic field solvers employing
the boundary element method.
A high frequency solver was then introduced mainly for antenna design. The scope of problems
the high frequency solver can handle since then has been radically increased. Due to customer
demand, a thermal module has been added to the suite of products to calculate thermal fields
generated by losses in the electromagnetic field.
More recently the more common finite element method has been included within the solvers.
State of the art development is now being done to combine both FEM and BEM within one problem
to provide the best simulation attainable.
Our specialty program LORENTZ has been developed for particle optics. The boundary
element method is the ideal tool for many charged particle optics applications.
INTEGRATED is committed to providing the best simulation tools possible enabling our customers to
create the best designs possible.

Integrated Environment
As the name of the company suggests, all the programs are seamlessly integrated
starting from a concept, the geometry and physics of the problem are entered, to
the type of solver is selected and the problem solved. Once the problem has been
solved, a vast number of parameters can be calculated or the field quantities displayed.
Integration with our CAD partners allows complex geometries to be imported directly into
the software. Tools are provided to enable the CAD geometry to be modified into a true
engineering drawing. All of this is done within the same design environment.

Optimization
The key to any simulation software is the ability to change a parameter parametrically and
find its effect. The parametric ability found in the INTEGRATED software is designed to solve this
problem. Geometric parameters and physical parameters are readily changed through an intuitive
interface. The intuitive interface makes the old style of scripting mostly obsolete.

True Modeling of Geometry
Like all the major CAD vendors INTEGRATED models the geometry using a NURBS (Non-Uniform Rational B-Spline)
representation. What this is the true geometry is maintained throughout the simulation process. In contrast
many simulation programs use a large number of flat patches to approximate the geometry.

CAD Partners
In addition to a built in geometric modeler, INTEGRATED has joined forces with major
CAD vendors to enable the seamless import of existing 3D mdoels. INTEGRATED
partners are PTC Corporation, AutoDesk, Solid Edge and Solid Works.
These products are required to be running alongside the INTEGRATED software. The model imported
from these CAD programs normally has to be massaged such that it can be used for a
boundary element or finite element solution.

Coupled Analysis (Multiphysics)
For many electromechanical systems it is important for the various solvers to be coupled.
For example, for induction heating the induced eddy currents are used for heating up a part. This magnetic
analysis is affected by the thermal analysis and visa versa. Thus, the electromagnetic solvers
need to be coupled with the thermal solvers. Such a coupling is done with INDUCTO.
For particle trajectory calculations, the path of the particle may be determined by a DC
magnetic and electric field as well as a time harmonic high frequency field. In such cases
all three fields need to be coupled to determine the path of the particle.
This is handled directly with LORENTZ.
Other systems can be coupled as determined by the physics of the problem.

Evaluation Period
INTEGRATED encourages prospective customers to make use of our 30-day evaluation of the software.
After making contact with one of our Sales Representatives, the program and a security key
are shipped. During the following 30 days, we encourage someone looking at the software to
make full use of our Technical Support staff, while using the software. As you will receive
a full working version of the software, you will be able to make sure it meets your design needs.

Excellent Technical Support
When using advanced simulation tools it is critical they are backed by people with years of
experience solving a wide range of problems. In many cases problems that may have taken the
user of the software days to figure out can be solved by a highly knowledgeable support person
in minutes. These problems may relate to the usage of the software, understanding the physics
of the setup of the problem, to interpreting the final results. INTEGRATED takes pride in the depth
and extensive knowledge accumulated by its support people over many years.

The INTEGRATED Advantage: Maximum Versatility of Field Solvers
BEM, FEM or Hybrid; Choose the Right Tool for Your Application
Since 1984, INTEGRATED has been the
industry leader in Boundary Element Method (BEM) CAE
software. BEM not only provides
the most accurate numerical field solutions, but also is the method of choice
for problems involving large open regions.
In contrast, field solvers using the Finite Element Method (FEM)
often require artificial "e;smoothing"e; algorithms to average out numerical
errors. In addition, artificial
boundaries must be used to handle open region problems, and even then, the
large meshes required may lead to excessively long solution times.
However, the relative simplicity of
implementation of FEM solvers leads to advantages when complex nonlinear
or transient analysis is required. FEM very often provides sufficient
accuracy for engineering purposes, and many problems are by their nature
inherently closed region. Recognizing
this, INTEGRATED incorporated FEM solvers to provide users the choice of both
methods. A significant side benefit of
having both BEM and FEM solvers is ability to check the validity
of solutions using two completely different analysis methods.
The most challenging analysis
problems occur when both nonlinearities and open regions are present.
Here again INTEGRATED takes the lead providing Hybrid
field solutions using BEM and FEM simultaneously to exploit the
strengths of both methods.

The INTEGRATED Advantage: High Frequency Problems
- Solution to an Electromagnetic(EM) model can be obtained in SINGULA is based on the
method of moments approach for open region problems and finite element method for closed region problems.
- A problem, which is considered as a big one in other techniques, does come under a
medium level problem. Hence, a costly parallel processing or distributed processing
computing facility is not required for solving high frequency EM problems in SINGULA.
- Simultaneous use of lossless and lossy electrical materials in a model is permitted
in SINGULA, whereas restrictions in some form exist in the other programs.
- Unlike in other programs, the waveguide sources can be used in the open or in
the closed region problems.
- Radiation patterns of antennas fed by waveguides surrounded by dielectric radomes
can accurately be obtained in SINGULA.
- Solution convergence with increased mesh density can be established easily
in SINGULA. This increases the confidence on the arrived solution.
- Some of the results can be coupled to the other INTEGRATED programs for the particle
trajectory calculation or thermal analysis
- The team of Engineers that are responsible for the development of SINGULA
offer the design and technical support to the users of SINGULA throughout.

The INTEGRATED Advantage: Charged Particle Trajectories and Beams
The LORENTZ module for charged particle calculations is available
with any INTEGRATED field solvers or combination thereof. Advantages of LORENTZ include:
- Best Field Solver
- No single method is the fastest or most accurate for every problem. However, accurate
field results are a critical start to getting correct trajectory calculations. INTEGRATED field
solvers have been proven in a diverse range of applications for over 20 years. BEM, FEM, and a hybrid
solvers are available to give the user a high level of choice. This also provides the ability to independently verify
the solution within the same program, which is much less effort than using two separate programs for
verification. The BEM method is especially noted for producing more accurate field results
than FEM in most cases.
- Mixed Fields
- In many applications it is necessary to use more than one field type. For example, a magnetic field
from coils plus electric fields from electrodes, or high frequency fields in a waveguide plus a DC bias field.
LORENTZ can have more than one field solver built in to handle these cases.
Furthermore, LORENTZ is able to import fields (see below).
- Importing Fields
- Users often want to specify a field rather than model it. Reasons include:
- making use of measured fields from the actual equipment
- theoretical studies of the effect of field shape to determine whether it is worth designing equipment to achieve that field shape
- making use of pre-existing results from software purchased prior to LORENTZ
The interface for importing include a simple text file format to interpolate from the input data, and
(for more advanced users) a DLL link.
- Secondary Emission
- LORENTZ provides two options for Secondary Emission calculations.
- Probabilities are determined from the energy of peak gain, the gain at this energy, and the mean
energy of the secondary electrons.
- A variety of inputs specify the individual probablities for reflection, rediffused electrons, and "true secondaries".
- Space Charge and Surface Charge
- All variants of LORENTZ with a static electric solver module included are able to model
space charge with a variety of standard emission regimes. In 2D programs it is also possible to model the charging of
dielectric surfaces. This includes the charge difference between the incident beam and any secondary electrons emitted.
- Mobility, Viscosity, Wind Tunnels, and Residual Gas
- LORENTZ Is able to model any particle trajectory with electric mobility, and macroparticles
with either mobility or viscosity. In both cases a wind speed can be applied to "Wind Tunnel" regions of the model. Advanced
users with external data for a wind tunnel velocity distribution can import this via a DLL that they write. Residual gases
provide random changes to particle momentum based statistically on the mass, radius, temperature and pressure of the gas molecules.
