Does anyone know if sympy is equipped to handle tensor based
Eular-Lagrange equations equations such as these?
Yes, with euler_equations from calculus module. But it doesn't
support tensor notation directly.

If you are talking about Lagrangian field theory the question is how do
you take a derivative with respect to the field and the gradient of the
field and not with respect to the position vector the field is a
function of.
