The control_reset_dof 100 and control_reset_value_constant 100 records together set a constant hydraulic head of 24.525 consistent with the phreatic level at $y=2.5 m$. The control_reset_dof 102 and control_reset_value_multi_linear 1012 records together set the multi-linear gravity field for the stresses.
