python - JModelicaのresult_file_name出力の形式は何ですか?

Question

次のコードを使用して、JModelica から結果を出力しています。

#!/usr/local/jmodelica/bin/jm_python.sh
import pyjmi
op = pyjmi.transfer_optimization_problem("BatchReactor", "model.mop")

opt_opts                                 = op.optimize_options()
opt_opts['n_e']                          = 40 # Number of elements
opt_opts['result_file_name']             = '/z/out'
opt_opts['IPOPT_options']['tol']         = 1e-10
opt_opts['IPOPT_options']['print_level'] = 0

res = op.optimize(options=opt_opts)

ファイル/z/outを調べると、次の構造になっています。

ここで、は...までさらに多くの行があることを意味しfinalTimeます。

しかし、これはどういう意味ですか？この出力のフォーマットはどこで指定されていますか?

ファイルのフォーマット方法に関するドキュメントが見つかりませんでした。ただし、私の意見では、次のようにすると、はるかに優れた出力が生成されます。

import StringIO
import numpy as np

def PrintResToFile(filename,result):
  def StripMX(x):
    return str(x).replace('MX(','').replace(')','')

  varstr = '#Variable Name={name: <10}, Unit={unit: <7}, Val={val: <10}, Col={col:< 5}, Comment="{comment}"\n'

  with open(filename,'w') as fout:
    #Print all variables at the top of the file, along with relevant information
    #about them.
    for var in result.model.getAllVariables():
      if not result.is_variable(var.getName()):
        val = result.initial(var.getName())
        col = -1
      else:
        val = "Varies"
        col = result.get_column(var.getName())

      unit = StripMX(var.getUnit())
      if not unit:
        unit = "X"

      fout.write(varstr.format(
        name    = var.getName(),
        unit    = unit,
        val     = val,
        col     = col,
        comment = StripMX(var.getAttribute('comment'))
      ))

    #Ensure that time variable is printed
    fout.write(varstr.format(
      name    = 'time',
      unit    = 's',
      val     = 'Varies',
      col     = 0,
      comment = 'None'
    ))

    #The data matrix contains only time-varying variables. So fetch all of
    #these, couple them in tuples with their column number, sort by column
    #number, and then extract the name of the variable again. This results in a
    #list of variable names which are guaranteed to be in the same order as the
    #data matrix.
    vkeys_in_order = map(lambda x: x[1], sorted([(result.get_column(x),x) for x in result.keys() if result.is_variable(x)]))

    for vk in vkeys_in_order:
      fout.write("{0:>13},".format(vk))
    fout.write("\n")

    sio = StringIO.StringIO()
    np.savetxt(sio, result.data_matrix, delimiter=',', fmt='%13.5f')
    fout.write(sio.getvalue())

次のようになります。
