[ANN] BloodFlowTrixi.jl: 1D and 2D Blood Flow Models for Arterial Circulation using Trixi.jl

I’m excited to announce the registration of BloodFlowTrixi.jl, a Julia package implementing 1D and 2D blood flow models for arterial circulation, derived from the Navier-Stokes equations. These models were developed during my PhD research in applied mathematics, with applications in cardiovascular pathologies like aneurysms and stenoses.

Key Features

  • 1D Blood Flow Model: Describes flow in compliant arteries using a reduced-order model derived under axisymmetric flow assumptions.
    Link to publication on 1D model

  • 2D Blood Flow Model: Extends the Navier-Stokes equations for thin arteries, capturing both longitudinal and angular dynamics in complex arterial geometries with curvilinear coordinates.
    Link to publication on 2D model

  • Both models are designed to work with Trixi.jl, a flexible high-performance framework for solving conservation laws using the Discontinuous Galerkin method.

Installation

When registration will be completed :
You can install the package with:

julia> ]
pkg> add Trixi
pkg> add https://github.com/yolhan83/BloodFlowTrixi.jl

Roadmap

Short-term goals:

  • Adding second-order 1D models.
  • Designing primitive variables for both 1D and 2D models.
  • Implementing proper tests for model validation.
  • Providing 3D visualizations of solutions for better interpretation.
  • Creating user-friendly interfaces for defining initial/boundary conditions and source terms.

Long-term goals:

  • Developing 3D fluid-structure interaction (FSI) models.
  • Supporting vascular network simulations by coupling the 1D and 2D models.
  • Adding autodifferentiation support for parameter optimization.

Acknowledgments

A big thanks to the Trixi.jl development team, whose framework made implementing and testing these models much easier. This package is released under the MIT license and is open for contributions!

I look forward to feedback, suggestions, and contributions from the community!
