Information

Introduction

For an introduction to the coupled simulation and for detailed information on Buildings.Rooms.CFD, please refer to Buildings.Rooms.UsersGuide.CFD. For a step by step guide on performing the coupled simulation, please refer to Buildings.Rooms.Examples.FFD.Tutorial.

Files for the Coupled Simulation

The source code of the FFD program is located at Buildings/Resources/src/FastFluidDynamics. The Buildings library contains precompiled versions of this source code in the subdirectories of Buildings/Resources/Library.

To run the coupled simulation with FFD, the following files are needed and provided in the Buildings library:

• dynamic link files located at Buildings/Resources/Library:
  • Windows: ffd.dll
  • Linux: libffd.so
• FFD input files for simulation parameters, called *.ffd and located at Buildings/Resources/Data/Rooms/FFD/
• Mesh files *.cfd and obstacles files *.dat generated by the program SCI_FFD and located at Buildings/Resources/Data/Rooms/FFD/. Note that the SCI_FFD program is maintained at https://github.com/FastFluidDynamics/Mesh.

Compiling library files

The FFD program can be compiled into a dlls using Microsoft Visual Studio Express in Windows and gcc in Linux. Compiled files are distributed with the Buildings library. If you want to compile the files yourself, proceed as follows:

• On Windows, method 1:
  1. Go to Buildings/Resources/src/FastFluidDynamics/
  2. Run compile.bat as administrator
• On Windows, method 2:
  1. Open cmd.
  2. Change to the directory Buildings/Resources/src/FastFluidDynamics/
  3. type compile.bat
• On Linux:
  1. Open a console.
  2. Change to the directory Buildings/Resources/src/FastFluidDynamics/
  3. Type make all

please note to make use you have the right of executing the compile.bat when using method 2 on Windows. To check the availability right click the file and choose Properties. Go to Security tab and edit if you don't have the access to execute the file.
