Does anybody know of a software (or software package) that can solve the Euler-Lagrange equations for a manifestly-covariant field Lagrangian density? Mathematica has a "Variational Methods" package, but none of the examples given are in manifestly-covariant form. I am not very experienced with any of the analytical computation softwares or their packages. Any help would be greatly appreciated! Thanks!

  • $\begingroup$ You might want to be more specific. How do the Euler-Lagrange equations look like? Are they PDEs, for example? $\endgroup$ Commented Jun 10 at 3:07
