error-950 max number of cutbacks exceeded, terminating

[namhgoo142]

I have oftenly faced the error as I presented in the title "max number of cutbacks exceeded, terminating". I guess that it is because of my severe deformation condition configured in rolling.yaml. file. I need to get deformation data when a material body is rolled significanly, i.e. over 70% reduction. Here I attach my rolling condition file, and I will very happy if an expert to modify the file for the severe reduction condition without facing error !

loadstep:

• boundary_conditions:
  mechanical:
  dot_F: [[x, 0, 0],
  [0, 0, 0],
  [0, 0, -0.02]]
  P: [[0, x, x],
  [x, x, x],
  [x, x, x]]
  discretization:
  t: 10
  N: 40
  f_out: 4
• boundary_conditions:
  mechanical:
  dot_F: [[x, 0, 0],
  [0, 0, 0],
  [0, 0, -0.04]]
  P: [[0, x, x],
  [x, x, x],
  [x, x, x]]
  discretization:
  t: 10
  N: 40
  f_out: 4

you could increase the number of cut back, Pls have a look at the example numerics file
