dwsimopt's Issues

example trouble: Single-mixed refrigerant (SMR) natural gas liquefaction process simulation optimization

Thank you for developing greatful tools!
I've been following the given examples verbatim, but I've encountered an issue as described below. It seems that the 'dof' argument is not being recognized. Are there any potential reasons for this you could think of?
I appreciate your assistance.

# Getting DWSIM path from system path
path2dwsim = []
for k,v in enumerate(os.environ['path'].split(';')):
    if v.find('\DWSIM')>-1:
        path2dwsim = os.path.join(v, '')
if path2dwsim == None:
    path2dwsim = "my_path"

# Loading DWSIM simulation into Python (Simulation object)
#sim_smr = SimulationOptimization(path2sim= os.path.join(dir_path, "examples\\SMR_LNG\\SMR.dwxmz"), 
#                     path2dwsim = path2dwsim)
sim_smr = SimulationOptimization(dof=np.array([]), path2sim= os.path.join(dir_path, "examples\\SMR_LNG\\SMR.dwxmz"), 
                     path2dwsim = path2dwsim)
sim_smr.savepath = os.path.join(dir_path, "examples\\SMR_LNG\\SMR2.dwxmz")
sim_smr.add_refs()

TypeError: init() got an unexpected keyword argument 'dof'``
