Introduction

WakeFoam library contains a custom inflow boundary condition, which uses a trained Neural Network to simulate the velocity field of a cylinder wake at the inflow boundary.

Implementation

When using the wakeFoam library the net.pt and wake_BC files must be present in the simulations folder.

Installation

cd $WM_PROJECT_USER_DIR
git clone https://github.com/ComputationalDomain/wakeFoam.git
cd wakeFoam
wmake

Parameters

1. flowSpeed Defines the flowspeed outside of the wake (Note: the velocity should be adjusted according to parameter D such that the Reynolds number stays equal to 100).
2. locationY Defines the location of the center axis in spanwise direction.
3. locationStreamwise Defines the distance of inlet surface from the cylinder (e.g. 8 diameters behind cylinder).
4. D Diameter of the cylinder.
5. streamwise streamwise axis (e.g. x).
6. spanwise spanwise axis (e.g. y).

Usage

There are tutorials located in wakeFoam/tutorials.
