(Alternatively, the command line code for the preceding step is

11. Apply loads:
As shown in the diagram, there is a load of 20 N/mm distributed on
the right-hand side of the plate. To apply this load:
Solution > Define Loads > Apply > Structural > Pressure > On Lines
When the window appears, select the line along the right-hand edge
of the plate and click OK. Calculate the pressure on the plate end by divid-
ing the distributed load by the thickness of the plate (1MPa).
Fill in the Apply PRES on lines window as shown next.
Note: The pressure is uniform along the surface of the plate; therefore,
the last field is left blank. The pressure is acting away from the surface
of the plate, and is therefore defined as a negative pressure. The applied
loads and constraints should now appear as shown in the following figure.
