L'acquisizione della MathCore è parte della strategia su larga scala di Wolfram per l'area d'ingegneria e dei relativi campi applicativi.
Oltre ai software MathCore, che continueranno a essere venduti e sviluppati, un particolare sforzo è in atto per integrare il cuore della tecnologia MathCore all'interno della tecnologia Wolfram.
Per i dettagli visita il sito MathCore o l'annuncio di Stephen Wolfram pubblicato sul blog Wolfram
MathModelica è un potente software per l’ingegneria
per la costruzione di modelli virtuali e la simulazione
di sistemi fisici.
Con MathModelica è possibile non solo ottimizzare
test ed esperimenti, ma anche analizzare fenomeni che sarebbe
impossibile studiare e comprendere in altro modo.
MathModelica è essenziale in moltissimi ambiti applicativi,
tra cui automobilistico, aeromobile, robotica, ecc; fornisce
una tecnologia che rende possibile costruire modelli e simulazioni
molto più vicini alla realtà di qualsiasi
altro software concorrente.
Model-Based
Design for Systems Biology and Multiengineering Systems
MathModelica
makes it possible to develop advanced multiengineering models
by simple drag and drop. MathModelica is a platform
for multiengineering simulation and model-based design for
dynamic systems. It provides an interactive graphical environment
and a customizable set of component libraries. With MathModelica
it is possible not only to optimize your tests and experiments,
but also to analyze phenomena that would otherwise be impossible
to study and understand.
MathModelica
is useful in a variety of fields, such as the automotive and
aircraft industries, robotics, and complex machinery. It provides
a technology that makes it possible to lift modeling and simulation
several levels closer to the real product than is possible
with today's de facto standard tools.
With MathModelica,
you will get the following benefits:
- Reduced
development time
By replacing physical prototypes with accurate models, you
can analyze design changes faster and with less expense.
- Reduced
testing time and costs
By replacing physical instrumentation, test benches, and
test procedures with different model analyses, both testing
time and costs can be reduced.
- Increased
quality and reduced maintenance costs
By getting increased knowledge about your system you can
improve quality and at the same time reduce maintenance
costs.
MathModelica
makes it cost-effective not only to develop model libraries
and experiments but also to maintain them. With its simplicity
and flexibility, it readily facilitates design updates and
correct decision-making in all stages of a product's life
cycle.
MathModelica
comes in two versions. MathModelica Professional is targeted at
projects and research in industry and academia, offering unparalleled
possibilities for analyzing results. MathModelica Student is equal to MathModelica
Professional in terms of functionality, speed, and output,
but is only available for students.
MathModelica
consists of three integral parts: the Model
Editor, where models are built with simple drag-and-drop
construction; the Simulation
Center, which handles the simulations to test and
evaluate the models; and the Mathematica
Link component, where fully translatable models can be
built, simulated, documented, and analyzed, all inside the
notebook environment. These parts are very tightly integrated
into a single engineering workbench for advanced modeling,
simulation, analysis, and documentation.
Model
Editor
The Model
Editor is a graphical and textual intuitive drag-and-drop
interface for the Modelica language. Models are assembled using components
from included, customizable model libraries; the class view
makes it simple to browse through different libraries. You
can easily change a model's properties in the parameter window.
Models can also be created in the notebook textual environment
and then transferred to the Model Editor for graphical viewing.
Simulation
Center
Once a
model is built it can be simulated in the Simulation Center
or transferred to notebooks for post-processing, analysis,
and documentation.
Simulations
and results are presented in the Simulation Center. Here you
can trim a model's parameters and initial values between simulations.
The tree browser makes it easy to find the parameters and
signals to plot. You can choose from 14 different solving
methods, including DASSL, Euler, and MEXX. When simulation
is completed, further analysis can be done using notebooks.
Unparalleled analysis capabilities
MathModelica offers several possibilities to analyze your results, for instance by studying animations or FFT analysis in Simulation Center. On top of that, MathModelica also makes it possible to connect to Mathematica*. This gives MathModelica users access to unparalleled facilities for mathematical computation, plotting, calculation, natural display of mathematical formulae, inline documentation, etc. within the powerful Mathematica notebook environment.
The interface is intuitive, allowing users to quickly enter the expressions that define a simulation, calculate them, and view the results in a variety of ways. A fully functional programming environment is provided, allowing the user to automate simulation tasks, e.g. batch jobs for optimization of a model. And, as the user works, documentation can be typed right into the notebook, making it much easier for others to understand what's been done.
* Note that Mathematica itself is not included in MathModelica.

We can deliver complete solutions (for example, the simulator of a plant or a robotic system) according to the customer's specifications. When needed, we can work together with the customer's R&D, helping to integrate state-of-the-art, multi-physics simulation technologies into their design processes and products. This means that the customer not only can have their plant or system simulated, but also employ the simulator to take decisions about the management or even the design of that system. In fact we use advanced technologies and methodologies for modelling and control, and also has the know-how to integrate them with the customer's know-how. Thanks to the multi-physics capabilities of the used technologies, we can deal with problems involving mechanical, thermal, electrical, electronic and even logic aspects simultaneously, simulating and assessing the entire system in a unitary manner (a great advantage with respect to other existing technologies).
In Italy this service is provided by Adalta with the support of top level professionists in the modelling, simulation and control fields.
