python3-mshr binary package in Ubuntu Lunar armhf

 mshr generates simplicial DOLFIN meshes in 2D and 3D from geometries
 described by Constructive Solid Geometry (CSG) or from surface files,
 utilizing CGAL and Tetgen as mesh generation backends.
 .
 This package contains the common Python 3 interface for mshr, and examples
 and demo programs.
 .
 This is the base package depending on specific mshr builds. By
 default mshr is built against dolfin using the preferred version of PETSc in
 /usr/lib/petsc (with 32-bit indexing), but the alternative version
 (64-bit PETSc) can be selected by setting the environment variable PETSC_DIR.
