scFLOW

Features

The new generation CFD software, scFLOW, has been developed to become the state-of-the-art tool with the breadth of new technologies and simple, practical features. The software is currently equipped with the new Solver with stability and three times faster calculation speed (at maximum) than before, as well as the new Preprocessor which helps entry-level users build complicated models and high-quality mesh. The software keeps on evolving.

Program Structure

Simplification of Preprocessor operations

Simplification of Preprocessor operations

From the CAD data to analysis mesh data, the required operations are grossly simplified compared to before. The conservation of assembly information and the settings of conditions on the parts bring the sense of continuity from the CAD operations and reduce the operational burden of the users.

Polyhedral mesher

Polyhedral mesher

Roughness/refinement distribution function of the automatic mesher has been improved. Polyhedral mesh can be generated with the sizes that are best suited for the geometry.

Viewer mode

Viewer mode

Preprocessor data can be displayed in the viewer mode without the Pre-/Post-processor license, when the license is taken by the mesher or by Postprocessor and is unavailable.

Operation logging by VB interface

Operation logging by VB interface

The operations in Preprocessor can be saved as a log file using the VB interface. Making the user scripting unnecessary, this makes the construction of an automated system affordable in a short period of time based on the files storing the operation logs.

Speedup of steady-state analysis

Speedup of steady-state analysis

Convergence performance has been improved and calculation time per cycle has been shortened for steady-state calculations by means of optimization of the calculation algorithm with the latest matrix Solver. Steady-state calculation speed can be doubled or tripled compared to before.

Stabilization of calculation

Stabilization of calculation

Even for a mesh data with elements of extremely low quality, the calculation can be stabilized by the automatic process for avoiding divergence.

Script functions

Script functions

Before, complicated settings, including time-/coordinate-dependent material properties or boundary conditions, required a coding and compilation of user-defined function in C language. With the script functions, compilation is not required. Functions can be written in Preprocessor based on JavaScript.

 

Virtual blade model

virtual blade model

Average flow field of a rotating blade (propeller) can be reproduced not by using the actual geometry but by setting some relevant parameters: Lift curve, drag curve, pitch angle, etc. This can be utilized, for example, in an average flow field analysis with axial windmills or waterwheel.

Moving elements (discontinuous mesh)

Moving elements (discontinuous mesh)

Calculations with moving objects can be performed: Rotation such as a fan, and translation such as cars passing each other. The calculation accuracy of element connections has been improved by revising the algorithm. For the HPC edition of Solver, memory consumption efficiency has been improved, which is expected to bring considerable effects in a multi-core calculation of large-scale data.

Overset mesh

Overset mesh

Motions with high degree of freedom can be set up compared to stretching or rotating motions by oversetting multiple mesh grids (static and moving regions).

Free surface (steady-state / transient)

Free surface

Shape of interface between gas and liquid can be simulated. Calculations by VOF method (Interface Capturing Method) are fast and accurate, and moving boundary function, overset mesh, particle tracking, etc. can be used in combination. For a phenomenon where the phase interface becomes stable, a steady-state calculation is possible, and the result can be obtained in a shorter amount of time than before.

Phase change

Phase change

As an extension function of free surface analysis (VOF method), phase change such as evaporation and condensation can be simulated. This can be used for an analysis of the coolant in a heat exchanger.
