Turbulence Boundary Layer

Build a structured boundary layer near walls for turbulent simulations.

Task list

• define a suitable struct/class that stores information on the geometry and
  mesh features

• generate an initial unstructured mesh with igl/cgal

• feed the mesh to libmesh

• solve a Poisson problem using libmesh with fixed boundary conditions on the
  wall(s)

• extract isosurfaces of the solution using igl

• use the isosurfaces to define the boundary layer

• mesh the boundary layer with a structured mesh using igl/cgal

• combine the strcutured boundary layer mesh with the unstructured mesh on the
  outside

External libraries

• libmesh

• igl

• cgal (optional)

Dependencies

• eigen

• openblas

• spack

Installation

Using spack: use the dedicated environment

spack env activate spack_env
spack concretize -f
spack install

After that, check that all required packages are available
