### 7.2.1 Pressure

The pressure load allows you to apply a pressure follower force to a surface. These pressure forces are always directed along the local surface normal and therefore change when the object undergoes a large deformation. Also note that, like prescribed constraints, a load curve is associated with the pressure force which by default will ramp the pressure value from zero to whatever value you entered.
