Example 3 with LinearSoilMaterial

[Mriganabh]

Hi all,

I am trying to run the example 3 on Mastodon with 20 layers of LinearSoilMaterial instead of the I-soil Material. While defining the materials block, I referred to the document on Mastodon Website. The material block in my input file looks like - 

[Materials]

  [./linear]

      type = LinearSoilMaterial

      layer_variable = layer_id

      layer_ids = '0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19'

      density = '0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367'

      shear_modulus = '46058.28 45635.44        45261.62        44876.52        44479.33        44069.15        43644.98        43205.66        42749.86        42276.24        41782.98        41268.17        40729.53        40164.37        39569.53        38941.18        38274.68        37564.29        36802.8 35980.97'

I encounter the following problem:

*** ERROR ***

Material property 'density', requested by 'gravity' is not defined on block 0

I am not sure why is that happening even though I am explicitly defining the densities of each layer in the material block. I have attached the input file for your reference.

Thanks,

Hi Mriganabh,

 

I recommend using ComputeIsotropicElasticityTensorSoil instead. Please follow the syntax in test/tests/materials/linear_isotropic_elasticity_tensor_soil/layered_soil_test_shear.i

 

If you have the same error, please let us know.

 

Best regards,

Chandu

Thank you, Chandu. 

The simulation runs when I use ComputeIsotropicElasticityTensorSoil. The Material block looks like:

[Materials]
  [./elasticity_tensor_block]
    type = ComputeIsotropicElasticityTensorSoil

    layer_variable = layer_id
    layer_ids = '0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19'

    poissons_ratio = '0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3'

    density = '0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367 0.00367'
    shear_modulus = '46058.28 45635.44 45261.62 44876.52 44479.33 44069.15 43644.98 43205.66 42749.86 42276.24 41782.98 41268.17 40729.53 40164.37 39569.53 38941.18 38274.68 37564.29 36802.8 35980.97'

    [../]
  [./strain_1]
    type = ComputeSmallStrain
    block = 0
    displacements = 'disp_x disp_y disp_z'
  [../]
  [./stress_1]
    type = ComputeLinearElasticStress
    block = 0
  [../]

I have also attached a working version of the input file of example 3 with linear soil for any future reference

Best,
