Jacobian Analyzer Error

[pj131611]

Greetings!

I just build and compiled Moose on a new laptop and everything works out well untill I tried "analyzejacobian.py". As far as I remember, all I need to do is "analyzejacobian.py file.i", then it will automatically output a json file that contains the jacobian. But it failed. The best I can get is when I do:

analyzejacobian.py -e main-opt -i main.i

and I got:

Error executing moose based application to gather DOF map.

I also tried main-opt -i main.i --ksp_view_mat with solve_type = NEWTON, and I got

WARNING! There are options you set that were not used!
WARNING! could be spelling mistake, etc!
There is one unused database option. It is:
Option left: name:--ksp_view_mat (no value) source: command line

So I'm pretty stuck at this point. Can anyone help me out? Thanks in advance.

Hello

In main.i you can add

[Executioner]
  petsc_options = '-ksp_view_mat'
[]

you might also be able to pass -ksp_view_mat on the command line, with a single dash

I see, thanks! What about residuals vector?

You can print those with either a DebugResidualAux auxkernel
Or there is an option in the Debug block iirc
