ufl.TrialFunction uses deprecated method
jorgensd opened this issue · comments
Minimal example in ufl:
def test2():
import ufl.finiteelement
cell = ufl.triangle
el = ufl.finiteelement.FiniteElement(
"Lagrange",
cell,
1,
(cell.topological_dimension(),),
ufl.identity_pullback,
ufl.H1,
)
mesh = ufl.Mesh(el)
mix = ufl.finiteelement.MixedElement([el, el])
W = ufl.FunctionSpace(mesh, mix)
u = ufl.TrialFunctions(W)
executed with pytest returns
test_warning.py::test2
/root/shared/ufl/ufl/core/expr.py:264: DeprecationWarning: Expr.ufl_domain() is deprecated, please use extract_unique_domain(expr) instead.
