Question about

I am performing the pressuremeter test that comes in the Material Models manual, section 17.2.3 pressuremeter test, but the mesh that I obtained does not look like the one in Figure 90, and in the calculation stage, it is not resolved. I believe that the problem may be when modeling the left boundary is placed 0.022 m away from the vertical axis of symmetry. I send a picture of the model.
