OasisMove - Moving Domain CFD Solver

GPL-3.0 codecov CI GitHub pages DOI

Left atrium flow

Fluid velocity (left) and mesh deformation (right) of a moving patient-specific left atrium model, simulated over two cardiac cycles lasting for $T=2$ s. The model is publicly available from this dataset.

Description

OasisMove is a high-level/high-performance open-source Navier-Stokes solver for fluid flow in rigid and moving domains written in Python/FEniCS, and is an extension of the computational fluid dynamics (CFD) solver Oasis. In OasisMove, the Navier-Stokes equations are expressed in the arbitrary Lagrangian-Eulerian formulation, which is suitable for handling moving domains. This moving domain solver has undergone rigorous verification and validation, and results have shown that OasisMove follows theoretical convergence rates, being second order accurate in time, and second and third order accurate in space with P1/P1 and P2/P1 finite elements. OasisMove has been developed with cardiovascular flows in mind, but is applicable to several flow problems within CFD.

Convergence rate analysis

Spatial convergence study of OasisMove performed by varying the characteristic edge length x. On the left, the L2 error for the velocity, and on the right the L2 error for the pressure, both following theoretical convergence rates. The solid lines represent the simulation results, and the dashed lines display the theoretical convergence rates. A similar study was performed to address temporal convergence, resulting in second order convergence (not shown here).

Installation

OasisMove and its dependencies can be installed using either conda, or by building and running a Docker container, and pip. For detailed installation notes see the installation guidelines.

Documentation

OasisMove's documentation is hosted here. This includes multiple tutorials, meant to guide the user through the basic steps of performing a computational fluid dynamic simulation and creating problem files.

For futher details on vanilla Oasis, please refer to its wiki or the user manual
