using ‘-O petsc.options.superlu_dist’ for an example in proteus tutorial

[whtsao]

I am testing the floating_body.py in /proteus_tutorial/2d on LSU HPC.
I think this file is the one runs with proteus/1.8.1.
Usually I put in my job script, but this time some errors come out.
The e.err is attached.
e.err.txt

It shows something like "AttributeError: usePETScOptionsFileExternal is not an option for class TwoPhaseFlowProblem"
I can still run the code without the ‘-O petsc.options.superlu_dist’ command.
But I am not sure if the parallel code is affected or not. If so, how can I fix it?
