In the following slides you can find very short presentation of our activity in Aeroelaticity and Flutter Laboratory.
Flutter simulations for full-scale aircraft
February 26th, 2010 by admin
Simulation for I22 IRYDA and I23 Manager airplanes performed with PUT Aeroelastic tools. For CFD part of the computation the DLR TAU-Code is applied. All computations were performed on a new 60 core InfiniBand Cluster of Virtual Engineering Group.
NEW: Flutter Laboratory
November 19th, 2009 by admin
Virtual Engineering Group o Poznan University of Technology entered a new cooperation.
The only one in Poland FLUTTER LABORATORY is a common establishment of Institute of Aviation in Warsaw and Poznan University of Technology. PUT is responsible for computational tasks while IoA deals with experiments and flight tests. The basis for our activity is the former EU-TAURUS project and scientific work of the group. The emphasis of the Laboratory and PUT activity is in practical, industrial applications. PUT has developed generic in-house aeroelastic-oriented FEM system coupled with the CFD code (presently DLR TAU-Code), with the use of coupling surface and AE-modules. PUT performs presently unsteady aeroelastic computations for the whole aircraft configurations. This activity is targeting computationally assisted tests of small aircrafts produced in Southern Poland.
In the pictures, the Institute of Aviation flutter model of I22 M93 and its virtual model by PUT are depicted.

Złożony w ramach Programu Operacyjnego Innowacyjna Gospodarka wspólny projekt Instytutu Lotnictwa i Politechniki Poznańskiej (WMRiT): “Opracowanie metody szybkiej estymacji właściwości aerosprężystych samolotu w czasie prób flatterowych w locie” uzyskał rekomendację do finansowania przy wysokiej punktacji.
Projekt dotyczy projektowania, budowy i certyfikacji lekkich samolotów, produkowanych w Polsce i jest w pewnym sensie modelowym zastosowaniem badań naukowych dla potrzeb przemysłu. Udział grupy Laboratorium Inżynierii Wirtualnej to modelowanie komputerowe samowzbudnych drgań samolotu powstających na skutek interakcji sił sprężystych niestacjonarnych i aerodynamicznych (aeroelastyczność, flatter).
Projekt jest wynikiem wieloletniej współpracy z partnerami z branży lotniczej w kraju i za granicą, wcześniejszego programu ramowego EU i jest nurtem alternatywnym w stosunku do powszechnie znanych, ostatnich inicjatyw “lotniczych” Wydziału.

Rozpoczęła się realizacja projektu własnego, finansowanego przez Ministerstwo Nauki i Szkolnictwa Wyższego.
Wieloskalowa analiza przebudowy adaptacyjnej kości pod wpływem stymulacji mechanicznej
Projekt ma na celu analizę wieloskalową przebudowy adaptacyjnej kości z uwzględnieniem modelowania procesu adaptacji mikrostruktury kości pod wpływem stymulacji mechanicznej. Uwzględnienie procesu adaptacyjnego struktury na poziomie mikrostruktury ma znaczenie kluczowe dla monitorowania zjawiska osteoporozy.

Please find the text from Wiki about Virtual Engineering. Now there are no doubts what we do and what is the future.
Virtual engineering
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Virtual engineering is defined as integrating geometric models and related engineering tools such as analysis, and simulation, optimization, and decision making tools, etc., within a computer-generated environment that facilitates multidisciplinary collaborative product development. Virtual engineering shares many characteristics with software engineering, such as the ability to obtain many different results through different implementations.
A virtual engineering environment provides a user-centered, first-person perspective that enables users to interact with an engineered system naturally and provides users with a wide range of accessible tools. This requires an engineering model that includes the geometry, physics, and any quantitative or qualitative data from the real system. The user should be able to walk through the operating system and observe how it works and how it responds to changes in design, operation, or any other engineering modification. Interaction within the virtual environment should provide an easily understood interface, appropriate to the user’s technical background and expertise, that enables the user to explore and discover unexpected but critical details about the system’s behavior. Similarly, engineering tools and software should fit naturally into the environment and allow the user to maintain her or his focus on the engineering problem at hand. A key aim of virtual engineering is to engage the human capacity for complex evaluation.
The key components of such an environment include:
- User-centered virtual reality visualization techniques. When presented in a familiar and natural interface, complex three-dimensional data becomes more understandable and usable, enhancing the user’s understanding. Coupled with an appropriate expert (e.g., a design engineer, a plant engineer, or a construction manager), virtual reality can reduce design time for better solutions.
- Interactive analysis and engineering. Today nearly all aspects of power plant simulation require extensive off-line setup, calculation, and iteration. The time required for each iteration can range from one day to several weeks. Tools for interactive collaborative engineering in which the engineer can establish a dynamic thinking process are needed to permit real-time exploration of the “what-if” questions that are essential to the engineering process. In nearly all circumstances, an engineering answer now has much greater value than an answer tomorrow, next week, or next month. Although many excellent engineering analysis techniques have been developed, they are not routinely used as a fundamental part of engineering design, operations, control, and maintenance. The time required to set up, compute, and understand the result, then repeat the process until an adequate answer is obtained, significantly exceeds the time available. This includes techniques such as computational fluid dynamics (CFD), finite elements analysis (FEA), and optimization of complex systems. Instead, these engineering tools are used to provide limited insight to the problem, to sharpen an answer, or to understand what went wrong after a bad design and how to improve the results next time. This is particularly true of CFD analysis.
- Integration of real processes into the virtual environment. Engineering is more than analysis and design. A methodology for storage and rapid access to engineering analyses, plant data, geometry, and all other qualitative and quantitative engineering data related to plant operation still needs to be developed.
- Engineering decision support tools. Optimization, cost analysis, scheduling, and knowledge-based tools need to be integrated into the engineering processes.
Virtual engineering allows engineers to work with objects in a virtual space without having to think about the objects’ underlying technical information. When an engineer takes hold of a virtual component and moves or alters it, he or she should only have to think about the consequences of such a move in the component’s real world counterpart. Engineers must also be able to create a picture of the system, the various parts of the system, and how the parts will interact with each other. When engineers can focus on the making decisions for particular engineering issues rather than the underlying technical information, design cycles and costs are reduced.
