BURLINGTON, Massachusetts, January 25, 2006

SoftInWay, Inc., is pleased to announce availability of a new version 1.7.05 of AxSTREAM™ - a professional tool for rapid turbomachinery flow path design and multidisplinary optimization that encompasses the complete engineering process of turbomachinery flow path conceptual design and multidisplinary optimization. It'll be first presented at daratechSummit2006, February 20-22, the Charles Hotel, Emerging Technologies Pavilion, Cambridge, Massachusetts.

AxSTREAM version 1.7.05 inherits all advantages of the preceded version appending some important features to amend and enrich the software capabilities in turbomachinery design and optimization.

The major new and weighty feature is addition a DoE-based optimization tool AxPLAN to Multistage Axial Compressor flow path computation. Besides performing preliminary design, cascades profiling, creation of airfoil 3D models, and generation of compressor maps, this addition allows to carry out compressor flow path optimization based on experiment planning technique.

New version provides the following additional key functional benefits to the turbomachinery designers that make the design and optimization process more sophisticated and convenient:

" Compressor flow path optimization with DoE-based tool (AxPLAN)
" Enhanced spatial airfoil profiling
" Visualization of additional throat features in 2D and 3D realization
" Replenished set of objective functions in AxPLAN
" Extended set of airfoil profiling types

The new functionalities streamline the process of turbine / compressor analysis, extend AxSTREAM's capabilities, noticeably decrease time required for the project performance, and facilitate end-user operation.

Some details of a new update are as follows:

" Compressor flow path optimization with DoE-based tool (AxPLAN)
Being previously successfully applied for turbine performance optimization, DoE-based AxPLAN™ module is enabled now for compressor computation. Optimization method used by AxPLAN requires only the values of the objective functions and state variables without their derivatives. It uses design of experiment (DoE) technique for the fast design space exploration generating compact formal models instead of huge original ones.

" Enhanced spatial airfoil profiling
Airfoil 3D profiling is strengthened noticeably. Now user can assign parameter distributions with the help of a spline, forming by this smooth surfaces easily and rapidly.

" Visualization of additional throat passage features in 2D and 3D realization

New post-processing capabilities make possible to visualize additionally channel throat's line, centroids line, minimum throat passage, and 3D throat location.

" Replenished set of objective functions in AxPLAN
A set of objectives is extended with some functions, which allow to further expand domain of optimization.

" Extended set of airfoil profiling types
A set of airfoil profiling types was modified and extended. From now on, it encompasses a profile's virtual model built with design angles given; profiling with given channel throat geometry preserved; usage of the profile loaded from ATLAS (AxSTREAM existing standard profiles database) with chord's scaling and with arrangement based on given throat geometry or stagger angle.

AxSTREAM with its unique capabilities gathered under one umbrella and supplemented with easy utilization of corporate design components (turbine, compressor, stage, airfoil) presented as libraries and special physical models is a choice for standalone exploration and for integration in any proprietary technologies within a company's organizations, as well.

In comparison with many other design codes & systems on the market, AxSTREAM features ultimate concentration of turbomachinery design procedures, providing fast and reliable solutions.
