CopyNodalVarsAction

Copies variable information from a file.

This action handles the initial_from_file_var Variables parameter as used below,

[Variables]
  [v]
    family = MONOMIAL
    order = CONSTANT
    fv = true
    initial_from_file_var = v
  []
  [lambda]
    family = SCALAR
    order = FIRST
    initial_from_file_var = lambda
  []
[]

This syntax is restricted to restarting from Exodus files. More information about alternative options to restart simulations may be found in the Restart/Recover system.
