To obtain X-Y graphs of the pressure of the soil on the left side and right side of the sheet-pile, the control_print_dof_line_* data records are used.

With index 900, printing of all solution fields is demanded, for the line starting at point ($x=3.01$,$y=2.0$) and ending at ($x=3.01$,$y=8.0$), so that is a line just to the right of the sheet-pile. The solution fields are printed at 10 points along that line. The fields are printed in text files, by example, velx.900, ..., sigxx.900, etc.

Similar with index 910 the solution fields will be printed along a line just to the left side of the sheet-pile.
