Attribute Error

Problem description

The ct.Solution().is_reversible() returns an error message. The error message was AttributeError: 'Solution' object has no attribute 'is_reversible'

Steps to reproduce

1. Open 'import cantera as ct g = ct.Solution('gri30.yaml') g.TPX = 300.0, ct.one_atm, 'CH4:0.95,O2:2,N2:7.52' g.equilibrate('TP') g.TPX = 300.0, ct.one_atm, 'CH4:0.95,O2:2,N2:7.52' g.equilibrate('HP')

rf = g.forward_rates_of_progress rr = g.reverse_rates_of_progress for i in range(g.n_reactions): if g.is_reversible(i) and rf[i] != 0.0: print(' %4i %10.4g ' % (i, (rf[i] - rr[i])/rf[i]))'

2. Run '....'
3. See error 'Traceback (most recent call last): File "C:\Users\Albert\PycharmProjects\chemEngProject\equilibrium.py", line 11, in if gas.is_reversible(i) and forwardRxn[i] != 0.0: ^^^^^^^^^^^^^^^^^ AttributeError: 'Solution' object has no attribute 'is_reversible''

Behavior

File "C:\Users\Albert\PycharmProjects\chemEngProject\equilibrium.py", line 11, in if gas.is_reversible(i) and forwardRxn[i] != 0.0: ^^^^^^^^^^^^^^^^^ AttributeError: 'Solution' object has no attribute 'is_reversible''

Additional context

Discovered when learning from Getting started tutorials.

This method was deprecated and removed in Cantera 2.6. The new way of writing this is:

gas.reaction(i).reversible

I'm going to transfer this to the cantera-website repository, since the error here is an out-of-date tutorial. Thanks for reporting this issue.
