Pulsatile blood flow modelling in python.

Requires:

  • Python3
  • ffmpeg

The solution to the differential equation is in pulsatile_flow.py.

Setting up environment

  • pip3 install virtualenv
  • python3 -m virtualenv venv
  • source ./venv/bin/activate
  • pip install -r requirements.txt

Running the model

Be sure to have activated the virtual environment before trying to run any of the code: source ./venv/bin/activate every time a new terminal is opened, or anytime after deactivate is run. To verify the environment is active;

  • which python
    • Verify this is ../your_local_directory/venv/bin/python
  • which pip
    • Verify this is ../your_local_directory/venv/bin/pip

To generate the 2D images and subsequent video for the animation:

  • python gen_images_2d.py
  • ./create_video_2d.sh

To generate the 3D images for the animation (for example):

  • python gen_images_3d.py --alpha 8
  • ./create_video_3d.sh img3d-8.00/

Create and render in one go:

  • python gen_images_3d.py --alpha 6 && ./create_video_3d.sh img3d-6.00
