Neohookean material with a axial stress load

[rnpratoori]

I want to run a 2D simulation with a stress/pressure loading in the x-direction and track the strain and stress components. I want to use the new lagrangian kernels to do it. Below are the relevant blocks I setup:

[GlobalParams]
    displacements = 'disp_x disp_y'
[]
[BCs]
    [left_symmetry]
        type = DirichletBC
        variable = disp_x
        boundary = left
        value = 0
    []
    [right_load]
        type = Pressure
        variable = disp_x
        boundary = right
        factor = 10
    []
    [bottom_fix]
        type = DirichletBC
        variable = disp_y
        boundary = bottom
        value = 0
    []
[]
[Physics/SolidMechanics/QuasiStatic]
  [all]
    strain = FINITE
    generate_output = 'elastic_strain_xx stress_xx'
    add_variables = true
    new_system = true
    formulation = TOTAL
  []
[]
[Materials]
    # Mechanical properties
    [strain]
        type = ComputeLagrangianStrain
    []
    [hyperelastic]
        type = ComputeNeoHookeanStress
        lambda = 1e9
        mu = 1e9
    []
[]

I get these errors:

The following error occurred in the Problem 'MOOSE Problem' of type FEProblem.check_inp(moose_srv)
Material property 'elastic_strain', requested by 'elastic_strain_xx_all' is not defined on block 0check_inp(moose_srv)
Material property 'stress', requested by 'stress_xx_all' is not defined on block 0check_inp(moose_srv)

How do I fix these? Or is there an example I can follow?

Hello

Use Debug/show_material_props=true to see the properties being defined and requested.
The names used by the materials might not match excactly, hence the error

This is the output I got -

*** ERROR ***
The following error occurred in the Problem 'MOOSE Problem' of type FEProblem.

Material property 'elastic_strain', requested by 'elastic_strain_xx_all' is not defined on block 0
Material property 'stress', requested by 'stress_xx_all' is not defined on block 0

As expected, this does not show elastic_strain, but I do not understand why that would be necessary looking at similar example files.

[GiudGiud]

It is necessary because your input file has:

    generate_output = 'elastic_strain_xx stress_xx'

so you are requesting this output. If you don't want this output, please remove it from this line

[rnpratoori]

Ok. So, I want them in the output. What should I add for it to work as expected?
I have ComputeLagrangianStrain and ComputeNeoHookeanStress in the materials block currently.

[GiudGiud]

@gambka do you know?
Looks like both these materials are outputting strains, but with a different name than "elastic"

[gambka]

@GiudGiud This input is using the new_system = True, which I don't have any experience with yet. @hugary1995 or @reverendbedford should be able to provide guidance on the usage of the new_system formulation.
