3D computation of a cardiac cycle with the Arbitrary-Lagrangian Eulerian solver of YALES2. This solver and the calculations were done in the I3M lab of the University of Montpellier by C. Chnafa, S. Mendez and F. Nicoud. The color in the movie represents the vorticity.

The grid on which the fluid problem is computed is extracted from 4D (3D + time) medical images from a patient. Ten 3D images are taken from different times during the heart cycle. A grid is extracted from one medical image using a segmentation protocol. Then, grid deformations are computed from the combination of an image registration algorithm and of interpolations process. Hence, boundary movements are extracted from medical images and applied as boundary conditions for the fluid problem, resulting in a patient-specific computation.
The spatial resolution is imposed to be close to 0.8 mm in all three spatial directions along the cycle, which yields grids of approximately three-million tetrahedral elements. Valves are modelled by immersed boundaries, and the heart is handled by a conformal mesh.

The grey particles and the grey film have the properties of water and the color represents the velocity magnitude in the gas. The Lagrangian particle are one-way coupled to the gas through drag for sake of simplicity.

3D computation of a cardiac cycle with the Arbitrary-Lagrangian Eulerian solver of YALES2. This solver and the calculations were done in the I3M lab of the University of Montpellier by C. Chnafa, S. Mendez and F. Nicoud. The color in the movie represents the vorticity.

The grid on which the fluid problem is computed is extracted from 4D (3D + time) medical images from a patient. Ten 3D images are taken from different times during the heart cycle. A grid is extracted from one medical image using a segmentation protocol. Then, grid deformations are computed from the combination of an image registration algorithm and of interpolations process. Hence, boundary movements are extracted from medical images and applied as boundary conditions for the fluid problem, resulting in a patient-specific computation.
The spatial resolution is imposed to be close to 0.8 mm in all three spatial directions along the cycle, which yields grids of approximately three-million tetrahedral elements. Valves are modelled by immersed boundaries, and the heart is handled by a conformal mesh.

=== '''Immersed boundaries on unstructured grids''' ([[User:Moureauv|Vincent Moureau]]) ===

On the left, 2D computation with YALES2 of the flow around two moving cylinders with an immersed boundary technique implemented for unstructured grids. The color represents the velocity magnitude. On the right, simulation of a stirred-tank reactor with YALES2. The mesh consists of 31 million tetrahedra. Simulation performed by V. Moureau from CORIA and N. Perret from Rhodia-Solvay.

Demonstration of 2D mesh deformation with YALES2. Only the velocity of boundaries is prescribed and the movement of the nodes is found by inverting an elliptic system. Edge swapping is also activated in this example.

</div>

== Motivation ==

YALES2 aims at the solving of two-phase combustion from primary atomization to pollutant prediction on massive complex meshes. It is able to handle efficiently unstructured meshes with several billions of elements, thus enabling the Direct Numerical Simulation of laboratory and semi-industrial configurations.

YALES2 was developed from 2007 to 2010 by [[User:Moureauv|V. Moureau]] and is maintained since 2011 by [[User:Moureauv|V. Moureau]] and [[User:Lartigue|G. Lartigue]] at CORIA and several other [[User|people]] in research laboratories.

* Temporal:
** 4th-order explicit time integration (RK4 and TFV4A) of convective terms
** explicit and implicit diffusion and source terms
* Stabilization: Cook & Cabot 4th-order artificial viscosity
* Linear solvers:
** PCG
** BICGSTAB, BICGSTAB2, BICGSTAB(2)
** Deflated PCG
** Deflated BICGSTAB(2)
** Residual recycling

== Data Structures ==
* 1D, 2D, 3D unstructured solver

* Data registration (int, real, char, node, elem, face, pair, scalar, vector, tensor)
* Optimized non-blocking MPI communications
* Parallel load balancing
* Automatic reconnection of periodic boundaries
* Automatic homogeneous mesh refinement
* IO formats: Gambit (Fluent), Ensight, prepartionned HDF5 (XDMF) with compression
* Cartesian mesh generator
* Partitioned mesh support for HDF5 independent of the number of processors
* Parallel interpolator for partitioned HDF5 meshes
* Automatic sponge layers
* Built-in Gaussian filters of arbitrary size

== Software engineering ==
* 280,000 lines of code
* Object-oriented fortran with modules (f90)
* Version management with SVN
* Inline documentation in the source code (XML + Latex)
* GUI with client/server mode (wxwidgets, C++)
* Automatic validation tests (AQAT, AVVT)
* Automatic dependency of f90 modules in makefiles
* Keyword-based input file
* Easy profiling with timers

== Gallery ==
Some computation examples are given in the [[YALES2_Gallery|gallery]].

== Performances ==
Thanks to highly efficient linear solvers, the speed-up of YALES2 is almost linear for meshes with several billion elements. These measures up to 21 billion elements were performed at IDRIS in France and at the Juelich Supercomputing Center in Germany.

== Motivation ==

YALES2 aims at the solving of two-phase combustion from primary atomization to pollutant prediction on massive complex meshes. It is able to handle efficiently unstructured meshes with several billions of elements, thus enabling the Direct Numerical Simulation of laboratory and semi-industrial configurations.

YALES2 was developed from 2007 to 2010 by [[User:Moureauv|V. Moureau]] and is maintained since 2011 by [[User:Moureauv|V. Moureau]] and [[User:Lartigue|G. Lartigue]] at CORIA and several other [[User|people]] in research laboratories.

== Solvers ==

YALES2 is based on a large numerical library to handle partitioned meshes, various differential operators or linear solvers, and on a series of simple or more complex solvers.
