python3-dolfinx-complex 1:0.5.2-2build1 (armhf binary) in ubuntu lunar

 DOLFIN is the Python and C++ interface of the FEniCS project for the
 automated solution of differential equations, providing a consistent
 PSE (Problem Solving Environment) for solving ordinary and partial
 differential equations. Key features include a simple, consistent and
 intuitive object-oriented API; automatic and efficient evaluation of
 variational forms; automatic and efficient assembly of linear
 systems; and support for general families of finite elements.
 .
 This package contains the Python interface for DOLFIN (Python 3).
 .
 This is the next-generation version of libdolfinx-dev (DOLFIN-X).
 The legacy version of DOLFIN (without complex number support)
 is provided by python3-dolfin.
