HORSES3D is a multiphysics environment where the compressible Navier-Stokes equations, the incompressible Navier–Stokes equations, the Cahn–Hilliard equation and entropy–stable variants are solved. Arbitrary high–order, p–anisotropic discretisations are used, including static and dynamic p–adaptation methods (feature-based and truncation error-based). Explicit and implicit time-steppers for steady and time-marching solutions are available, including efficient multigrid and preconditioners. Numerical and analytical Jacobian computations with a coloring algorithm have been implemented. Multiphase flows are solved using a diffuse interface model: Navier–Stokes/Cahn–Hilliard. Turbulent models implemented include RANS: Spalart-Allmaras and LES: Smagorinsky, Wale, Vreman; including wall models. Immersed boundary methods can be used, to avoid creating body fitted meshes. Acoustic propagation can be computed using Ffowcs-Williams and Hawkings models.
HORSES3D supports curvilinear, hexahedral, conforming meshes in GMSH, HDF5 and SpecMesh/HOHQMesh format. A hybrid CPU-based parallelisation strategy (shared and distributed memory) with OpenMP and MPI is followed.
The following external routines/libraries can be used with HORSES3D, but are not necessary: METIS, MPI, HDF5, MKL, PETSc.
HORSES3D is an object-oriented Fortran 2008 solver, that can be compiled using gcc and the Intel compiler, in Unix-based operating systems.
-
We recommend using recent versions of such compilers (2019 or newer).
-
Make is necessary (e.g., Gnu's version, which is included in most linux distributions).
-
Supported meshes are in GMSH, HDF5 (HOPR) and SpecMesh/HOHQMesh format.
-
Post processing can be performed in tecplot or paraview.
-
Go to the Solver folder and configure the project
cd Solver ./configure
-
Build the solvers using
make
(see manual in the/doc
folder)make clean make all [options]
with the desired options (defaults are bold):
-
PLATFORM=MACOSX/LINUX
-
MODE=DEBUG/RELEASE
-
COMPILER=ifort/gfortran
-
COMM=PARALLEL/SEQUENTIAL
-
ENABLE THREADS=NO/YES
-
WITH MKL=y/n
For example:
make all COMPILER=ifort COMM=PARALLEL
-
-
Run the solver for the parameter file file.control (see manual in the
/doc
folder and examples in/test
)./horses3d.ns file.control
-
Test cases for various physics are provided in the folder
/test
-
