# BasicSolver Variants
|
|
|
|
## Introduction
|
|
|
|
This folder contains variants of the NuSiF basic solver. The basic solver does
|
|
not allow obstacles within the domain.
|
|
|
|
All basic solver variants include two test cases for validation:
|
|
|
|
* dcavity - Lid driven cavity
|
|
* canal - Channel flow
|
|
|
|
## 2D solver variants
|
|
|
|
### Sequential solver (2D-seq)
|
|
|
|
This is the basic sequential version. Gnuplot result visualization.
|
|
|
|
### MPI parallel solver (2D-mpi)
|
|
|
|
The simplest possible MPI parallelization with domain decomposition in one
|
|
direction and communication just based on simple send and recv calls.
|
|
Gnuplot result visualization.
|
|
|
|
A MPI parallelization with two-dimensional domain decomposition using MPI
|
|
virtual topologies.
|
|
Gnuplot result visualization.
|
|
|
|
A MPI parallelization with two-dimensional domain decomposition using
|
|
neighborhood collective call instead of send and recv calls.
|
|
Gnuplot result visualization.
|
|
|
|
The final version of the 2D MPI parallel solver. All MPI calls are contained in
|
|
a single communication module. The rest of the code does not depend on MPI.
|
|
This version is prepared to also compile and run without MPI.
|
|
VTK result visualization.
|
|
|
|
## 3D solver variants
|
|
|
|
### Sequential solver (3D-seq)
|
|
|
|
This is the basic sequential version.
|
|
VTK result visualization.
|
|
|
|
### MPI parallel solver (3D-mpi)
|
|
|
|
A MPI parallel solver with 3D domain decomposition using MPI virtual topologies
|
|
and neighborhood collectives. All MPI calls are contained in a single
|
|
communication module. The rest of the code does not depend on MPI. This version
|
|
is prepared to also compile and run without MPI.
|
|
VTK result visualization.
|
|
|
|
Identical to the 3D-MPI variant but using MPI-IO for VTK result file output.
