NOTES

  1. A face load is a set of known, time varying distributed pressures applied to a body BodyName, which must be a shell or membrane elements.
  2. The face load consists of up to three individual pressure components; the nature of each loading component is defined by the first keyword appearing in the @LOADING_COMPONENT subsection, as detailed below.
    • @APPLIED_PRESSURE_ALONG_i1: distributed pressure acting along inertial axis i1.
    • @APPLIED_PRESSURE_ALONG_i2: distributed pressure acting along inertial axis i2.
    • @APPLIED_PRESSURE_ALONG_i3: distributed pressure acting along inertial axis i3.
    Each pressure component is associated with a pressure table PresTblName. The distributed pressures have units of force per unit area of the surface defining the corresponding shell or membrane element.
  3. Each loading component is assigned a scaling factor, sca, that multiplies the loading values defined in the corresponding loading table.
  4. Each loading component is assigned a time function, Fun1DTimeName, of type TIME_FUNCTION, that determines the time history of the corresponding loading component.
  5. If the follower force flag is FfFlag = YES, the specified pressure distribution component will be treated as a follower pressure, i.e. the direction of the applied forces and moments will rotate according to the rotation of the structural point where the loading is applied.
  6. It is possible to attach comments to the definition of the object; these comments have no effect on its definition.
