SoftInWay, Inc. is a global R&D engineering company specializing in the development of efficient turbomachinery components and systems by offering its integrated and automated software platform, AxSTREAM ® for all steps of the turbomachinery design, redesign, analysis, and optimization process (including complete 3D design, thermodynamic cycles, rotor dynamics, and secondary flow and cooling system simulation).


Products offered by SoftInWay : 


AxSTREAM® Software Platform


The AxSTREAM® software platform for multidisciplinary design, analysis and optimization provides an integrated and streamlined approach to turbomachinery design. This best-in-class software solution encompasses the complete process for radial, axial and mixed flow turbomachinery design. This includes gas and steam turbines, compressors, blowers, pumps, fans, rotors, bearings, secondary flows, and cooling. AxSTREAM®’s capabilities and features include:

  • Meanline/Streamline Analysis allows users to check the performance, velocity triangles, leakages, etc. of a machine for any set of boundary conditions as well as review the streamwise and spanwise distribution of thermodynamic, kinematic and loss parameters.
  • AxMAP for performance mapping of operational conditions and geometric variations for a given design.
  • AxPLAN of various design tasks, utilizing fast design of experiment (DoE) study methods.
  • Profiling and 3D Blade Design to create and edit 3D airfoils via various geometric features and interactive charts for plane sections profiling and 3D blade stacking.
  • AxCFD for the calculation of 2D and 3D analysis in blade-to-blade channels.
  • AxSTRESS for rapid 3D finite element analysis on blades and attachments.
  • AxSLICE used for reverse engineering to extract the profile geometry of 3D blade models to analyze existing machines in the AxSTREAM software platform
  • Bearing Calculation and Analysis to determine the hydrodynamic performance and mechanical characteristics of journal (radial load and axial thrust), aero, squeeze film dampers and rolling element bearings as well as annular seals.
  • RotorDynamics used to calculate rotor trains natural frequencies (including modes shape), unbalance response and conclude on stability for both lateral and torsional analyses while accounting for accurate bearing and support characteristics.
  • RotorDesign for the complete design of rotors based on blades number, their position and attachments, etc. which can be used as standalone or as a link between flow path design and rotor dynamics analysis.

EthosEnergy Italia 

AxSTREAM® was purchased by EthosEnergy Italia SpA in 2017 from SoftInWay with the specific purpose of supporting the design phase their rotor LTE/LTA program. AxSTREAM®, with the addition of AxSLICE™ module, is able to capture the geometry directly from any 3D CAD, recognize the flow path, slice the airfoils automatically on many sections and generate the distribution of all the static and total physical properties upstream and downstream each stator and rotor stage. This represents a real advantage with respect to the previous streamline software generation, which was not able to dialogue directly with the 3D CADs and all airfoils geometries had to be input numerically, requiring a huge effort in terms of man-hours.         (Read more…)
