Advanced CFD Technology for Turbomachinery Flows

FINE/TurboTM is a fast and accurate Flow Integrated Environment available for the simulation of internal, rotating, and turbomachinery flows, and this for all type of fluids. FINETM/Turbo integrates a fully hexahedral, highly automated grid generator, AutoGridTM, advanced density-based numerical algorithms with local preconditioning. The package is completed by CFViewTM, an advanced visualization tool. Users pilot FINETM/Turbo through an easy-to-use and intuitive interface for fast solution set-up, or through a batch process for transparent integration in a design cycle.

Advanced Rotor/Stator Interaction Techniques
FINETM/Turbo contains features for multiple blade rows and steady or unsteady interaction. Different levels of approximation are available, depending on the nature of the phenomena and the frequency spectrum to be captured.

The non-linear harmonic capability allows significant speed-up for single and multistage unsteady analysis. The table on the right shows figures for a single stage radial turbine, computed on a single processor (3 harmonics have been selected).

SIMATIC S7-PLCSIM


Simulation systems provide effective support with the develop­ment of programs and the following actual application. In the automation environment, a simu­lated test environment including PLC and process reduces start-up times and thus costs, for example Early discovery of programming errors and optimization of program sections enable the optimized and error-free use of the programs in the actual system.
If a program is modified, it can be tested prior to loading it onto the plant control system.

Application
SIMATIC S7-PLCSIM simulates a controller for functional testing of user blocks and programs for S7-300 and S7-400 on the programming device/PC. Online access and test functions of the programming tools can be carried out in exactly the same manner as with a real controller. This allows the entire program test to be carried out on-site in the development office.
The facilty to simulate the communication via MPI, PROFIBUS DP and TCP/IP is new and ensures a high degree of flexibility in the simulation.

Function
S7-PLCSIM executes the user program just like a real controller (special functions such as F technology only conditionally). During program execution, different process values can be monitored and changed via a simple user interface (e.g. switching inputs/outputs on or off).

Link-up with an external process simulation
The S7-ProSim interface is used for linking up to external process simulation systems. Dynamic access to process values is possible via this interface. The PROSIM Interface is using the COM and is programmable for example with the Microsoft Visual Studio C++ V6.0 and the Microsoft Visual C++ .NET.

FlowJo software reads flow cytometry data and facilitates complex data analysis in a graphically intuitive way.

FlowJo is a scientific analysis program designed for flow cytometric data. It performs comprehensive analyses of up to thousands of samples containing millions of events in a high dimension event space.

FlowJo puts a friendly front-end on some very complex multivariate analysis operations and makes it possible to generate powerful batch processes merely by dragging icons around. Use it to process hundreds of samples, and create comprehensive tables and graph layouts. Rich polygon gating.

• Histogram and other plot overlays
• Cell cycle analysis
• Calcium flux analysis
• Proliferation analysis
• Quantitation
• Cluster identification and backgating display

WAsP is a PC-program for the vertical and horizontal extrapolation of wind climate statistics.

It contains several physical models to describe the wind flow over different terrains and close to sheltering obstacles. WAsP is an implementation of the so-called wind atlas methodology, which may be summarised as follows:

Analysis

• time-series of wind speed and direction —> observed wind climate (OWC)
• observed wind climate + site deion —> regional wind climate (wind atlas data sets)

• regional wind climate + site deion —> predicted wind climate (PWC)
• predicted wind climate + power curve —> annual energy production (AEP) of wind turbine

• predicted wind climates + WTG characteristics + wind farm layout —> wind farm wake losses
• annual energy productions + wake losses —> net annual energy production of entire wind farm

Animation tool for handling extremely large finite element models

Animator4 was originally designed as a post-processor for highly nonlinear dynamic applications such as LS-DYNA or similar codes.
The program is based on years of experience in project work for the automotive industry. Earlier versions of the program had been exclusively developed for the automobile manufacturers VOLKSWAGEN and AUDI.

The great success it had within these companies encouraged GNS to rewrite the code using the C programming language as well as OpenGL and MOTIF. Since its first appearance on the market in 1996, Animator4 has received a great deal of recognition. It is now used by a wide range of companies within engineering.

• Animator4 is the perfect animation tool for handling extremely large finite element models.
• Animator4 offers maximum speed using very little memory.
• Animator4 offers comprehensive functionality to easily
  and carefully verify and validate the results of even the most complex calculations.
• Models can be animated using a variety of different modes such as wire frame mode, shaded mode with or without element mesh, edge mode, and, of course, fringe mode. The different modes can also be combined within one model to get excellent graphics to efficiently present simulation results to designers or product managers.
• Curves of nodal and element time history data can be plotted while running the animation just by picking them with the mouse.
• Cross section views can be animated, and cross sections of the undeformed geometry can be compared to any deformed state.
• A 3D option is also available allowing use of all the above features with real 3D animation.

• split list of system-variables into system (A4) and environment variables
• implement dragging of curve-positions in curveview
• all function properties in the open dialog are now also generally saved so that modi?ed values (i.e.range, degrees) that were used last are also available for ?les that are not in the history.
• Tcl-API extensions: GNS_get_distance, GNS_get_elongation, GNS_get_relative_velocity, GNS_get_view_list, GNS_get_slot_list, GNS_get_state_list, GNS_get_button_list, GNS_get_curve_list, GNS_get_curve_list, GNS_get_pid_list and GNS_get_curve_list
• made windows batch version run without any GUI (e.g via ssh)
• ?xed ticket #2009042310000254: -D startup arg reads only geometry
• changing slot target after creating new slot and before starting autoload, so that the user can setup a second read command while autoload is in process
• enhance quality of grid fonts by antialiasing (opt ant on/off)
• Using "DontMaximizeSubWindowOnActivation" in workspace area. This allows user to mix maximized views with normalized views even in tabbed mode. Also, windows are not maximized automatically when the tabbed mode is enabled. The ?ag suppresses some work that otherwise is automatically done by Qt (and perhaps is unwanted by the user).
• Implemented entering wildcards in the lineedit of the ?le dialogs. This ?lters the display of ?les and directories.

• Abaqus:
  
  • added support for v6.9.1
• Dyna3D:
  
  • extended curve data support: abstat cpm, glstat, rbdout, sleout, dcfail data amount extended
• Pamcrash:
  
  • continuing reading pamcrash deck even if an include ?le is missing
  • include ?le handling refactored, now include ?les are read as soon as the keyword INCLU is met.
