CopyNodalVarsAction

Copies variable information from a file.

This action handles the initial_from_file_var Variables parameter as used below,

  [v]
    family<<<{"description": "Specifies the family of FE shape functions to use for this variable"}>>> = MONOMIAL
    order<<<{"description": "Specifies the order of the FE shape function to use for this variable (additional orders not listed are allowed)"}>>> = CONSTANT
    fv = true
    initial_from_file_var<<<{"description": "Gives the name of a variable for which to read an initial condition from a mesh file"}>>> = v

  [lambda]

    order<<<{"description": "Specifies the order of the FE shape function to use for this variable (additional orders not listed are allowed)"}>>> = FIRST

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.
