NFLOW

Particle-based

3D CFD Software

New CFD, beyond Limits

NFLOW is the first fluid analysis simulation software of Korea developed by applying the particle method (SPH Method), which can be applied in all sectors requiring the analysis of fluid.

 

Compared to previous CFD software that requires mesh for analysis, users can more accurately and reliably analyze the movement of fluid without even creating a separate grid.

 

Also, you can experience superior performance in multi-phase, interaction with rigid body, free surface analysis and particle representation.

NFLOW

APPLICATIONS

NFLOW constantly researches and develops

to effectively deal with problems

regarding complex physical phenomena.

 

It is applied in diverse industrial fields

such as machinery, manufacturing,

construction, civil engineering, shipbuilding,

maritime, disaster and safety.

NFLOW is BEST

Best Solver Suitable for Fluid Analysis

NFLOW Solver is based on a particle method using SPH where each particle has physical quantity that enables it to perfectly implement physical phenomenon. In particular, it can analyze the free surface analysis and the multi-phase flow where different liquids mix without additional numerical method.

 

Also, this solver has high accuracy and reliability by using optimized algorithms such as the Navier-Stoke equation and conservative equation that are suitable for liquid analysis.

  • In nonlinear free surface liquid analysis, advantageous in analyzing physical phenomenon of complex shapes compared to analysis method using a grid

  • Lack of numerical dispersion by convection term that can be caused from grid-based Eulerian method and perfectly preserves the mass

NFLOW is SIMPLE

Simple Pretreatment without Need for Mesh Work

Advantages of NFLOW Solver

By using Lagragian method with SPH solver, there is no need for mesh such as FVM or FEM and therefore can save time and deal with the difficulty of creating mesh.

<Comparison of Pretreatment Process between Particle-based CFD NFLOW vs. Other CFD S/W>

  • By employing particle method, overcome the twisting of grids and technological limitations such as distortion in creating mesh from ordinary CFD pretreatment stage

  • With simple pretreatment stage by entering numbers and attributes, nonprofessionals can easily prepare for analysis

NFLOW is FAST

Multi GPU Algorithm for Analysis Speed improvement

Multi GPU is the technology using a multi-professional graphics processing unit (GPU) to intelligently improve the performance of applications and significantly increase the velocity of workflow, which provides overwhelming velocity compared to traditional CPU software.

<Improve Analysis Speed by using Multiple GPUs>

  • Each GPU expands its respective area according to the prescribed length.

  • Even if the simulation area is large, it does not cause any problems in searching for nearby elements.

NFLOW is EASY

Customized Comprehensive Work Environment

It provides comprehensive work environment for pretreatment, analytic computation and post treatment to improve user convenience and efficiency. Also, it provides visual guidance on 3D simulation result and easy print out in the program using chart and video functions

NFLOW

HIGHLIGHT

NFLOW, based on reliable and quick solver, offers broad physical models such as multi-phase liquid analysis and floating body liquid analysis and fluid flow analysis.

Multi-Phase FLOW

NFLOW is capable of analyzing the flow by mixing two or more liquids of varying properties. Multi-phase analysis is a part of liquid analysis that can be applied to diverse industries such as petrochemical, chemical and pharmacology. Physical understanding in such multi-phase phenomena has an important role in optimization of production and designing process.

+  Oil & gas flow analysis

+  Analysis of movement of air bubbles in liquid

+  Measurement of constituents and compositions of multi-phase liquid flowing in a pipe

Laminar & Turbulent FLOW

NFLOW is capable of analyzing the flow types such as laminar flow and turbulent flow in single-phase and two-phase. It analyzes laminar movement where flow particles form a layer and make movements along a stable path, turbulent flow where flow particles move along irregular paths and laminar-turbulent transient flow.

Floating Boundary

NFLOW is capable of analyzing the phenomenon of floating body in the flow of fluid through floating boundary. In this case, the solid itself has a boundary condition by giving solidified particle in the liquid consisting of particles, and the solids consisting of particles are characterized by solid bodies instead of flexible bodies. In this case, the phenomena of floating bodies on water, a boat floating on water and objects such as trees and rocks floating down during landslide can be analyzed.

 

+  Analysis of rockslide during landslide

+  Analysis of flow pattern by waves due to mooring bodies such as ships

+  Analysis of movement of floating bodies by flow of liquid

+  Analysis of collapsing phenomenon by tsunami and tidal wave

Fluid FLOW

NFLOW is capable of analyzing the mechanical problems caused by the flow of incompressible and compressible fluid. In the applied areas, it can effectively analyze the mixture and flow of fluid by rotation and analysis of flow inside a pipe.

+  Analysis of flow of ejector based on the changes in length of straight pipe and diffuser

+  Analysis of flow inside fuel tank and pipe

+  Analysis of mixture and flow of fluid by rotation
