# (Fedora MPI guidelines), so nothing provides python3dist(fenics-dolfinx); the
# generated requirement could never be met. The explicit python3-dolfinx-openmpi
# Requires below carry the same 0.11 range.

%global _description %{expand:
dolfinx-external-operator implements UFL's ExternalOperator for DOLFINx: a
term in a variational form whose values (and derivatives) are computed by
user code rather than by UFL. The code can be plain NumPy, Numba, JAX or
PyTorch; with JAX or PyTorch the derivatives needed for Newton's method can
come from automatic differentiation. Typical uses are constitutive models in
solid mechanics (plasticity, data-driven hyperelasticity) and other
pointwise models that are awkward to write in UFL.}

Summary:        %{summary}
# DOLFINx is packaged per MPI implementation; openmpi is the one this COPR
# builds. Numba, JAX and PyTorch are used only by user code and the demos.
Requires:       python3-dolfinx-openmpi >= 0.11.0
Requires:       python3-dolfinx-openmpi < 0.12
Recommends:     python3-numba
