Python Hybrid Flow solver (pHyFlow) is a hybrid flow solver that couples a Navier-Stokes grid solver with a vortex blob solver aimed at solving flows around complex geometries.
pHyFlow is based upon several libraries. In order to have a functional version of pHyFlow follow the following instructions. We assume the user starts with a fresh installation of ubuntu 12.04LTS. This sequence of instructions is known to result in a working installation. If you have an already installed ubuntu 12.04LTS or a more recent one, try following these instructions. If you have any issue please contact us.
In the terminal line type:
sudo apt-get install build-essential
Go to this link: https://developer.nvidia.com/cuda-downloads?sid=336852 and download the Ubuntu 12.04 64bit DEB file or the one corresponding to your Ubuntu version. Follow the DEB installation instructions, basically:
sudo dpkg -i cuda-repo-<distro>_<version>_<architecture>.deb
sudo apt-get update
sudo apt-get install cuda
Add the environment variables to cuda in your .bashrc:
export PATH=/usr/local/cuda-CUDAVERSION/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-CUDAVERSION/lib64:$LD_LIBRARY_PATH
Note that CUDAVERSION is the version of the cuda installed. 5.0, 5.5 or 6.0 or any other. Therefore, for CUDA 6.0:
export PATH=/usr/local/cuda-6.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-6.0/lib64:$LD_LIBRARY_PATH
NOTE: most likely there will be only one CUDA installation in your computer,
nevertheless check if in /usr/local there is a folder named cuda with
the CUDA version you wish to use. If not you will probably have several
folders, one for each version: cuda-5.0, cuda-5.5, cuda-6.0. In that case,
you need to make a symbolic link to the version you wish to use. For
example if you wish to use cuda-6.0 do the following:
sudo ln -s /usr/local/cuda-6.0 /usr/local/cuda
In the terminal line type:
sudo apt-get install git
You have two options: you can follow dorsal's instructions in http://fenicsproject.org/download/installation_using_dorsal.html
or just download https://bitbucket.org/fenics-project/dorsal/get/master.tar.gz
unpack it, change the install directory in dorsal.cfg to the one you wish, for example install_dir_FEniCS,
and use the option
STABLE_BUILD=false
then run:
./dorsal.sh
IMPORTANT: follow the instructions, check the software to be installed before continuing with dorsal's installation.
Add the environment variables to FEniCS in your .bashrc:
# FEniCS environment variables
source install_dir_FEniCS/FEniCS/share/fenics/fenics.conf
In the terminal line type:
sudo apt-get install libboost-python-dev
In the terminal line type:
sudo apt-get install python-sparse
In the terminal line type:
sudo apt-get install python-setuptools
You can follow the instructions in http://mathema.tician.de/software/pyublas or simply download it:
git clone http://git.tiker.net/trees/pyublas.git
then change directory to the pyublas directory and configure:
python configure.py
build pyublas:
python setup.py build
install pyublas:
sudo python setup.py install
copy pyublas include files to /usr/include
sudo cp -r pyublas/include/pyublas /usr/include
In the terminal line type:
sudo apt-get install ipython
In the terminal line type:
sudo apt-get install python-scipy
In the terminal line type:
sudo apt-get install python-matplotlib
Download the latest version from https://bitbucket.org/spyder-ide/spyderlib/downloads unzip it and run:
sudo python setup.py install
As an alternative you can follow the instructions here: https://pythonhosted.org/spyder/installation.html.
Create a directory for your pHyFlow download folder. Move into that folder and download the latest version of pHyFlow using git:
git clone https://[email protected]/gorkiana/phyflow2.0.git
Change in the install.py file the line
libParent = '/media/DATAPART1/programs/lib/python' # root install directory
into whatever directory you wish to use to install pHyFlow, for example /home/your_username/install_pHyFlow_parent_dir/. Then type on the terminal line:
run python install.py
Add to your .bashrc the pHyFlow install directory in order to be able to import pHyFlow into python:
# add pHyFlow to the python path
export PYTHONPATH=$PYTHONPATH:/home/your_username/install_pHyFlow_parent_dir
Download the lastest release of fenicstools from https://github.com/mikaem/fenicstools/releases
Extract it into /home/your_username/install_pHyFlow_parent_dir/, as used in (13) and rename the extract folder to fenicstools. Now you do not need
to add this folder to PYTHONPATH again since it was already done in (13).
