Force and moment load (Simcenter Samcef)

Use the Force command to define the magnitude and direction of a force load. You can define the magnitude of the load as a constant value, expression, or field that defines how force load varies with time.

Use the Moment command to define the magnitude and direction of a moment load. You can define the magnitude of the load as a constant value, expression, or field that defines how force load varies with time.

You can also define a follower force or moment.

Define a force load on geometry or directly on nodes

You can define a force load on selected:

• Geometry (such as, curves, points, mesh points, polygon faces, or polygon edges).

• Nodes

If you define the force load on geometry, the software then maps the force loads to the corresponding nodes.

You can use the Type list in the Force or Moment dialog box to specify how you want to define the force load. The geometry or FE entities to which you can apply a force load depend the option that you select from the Type list.

For the Magnitude and Direction and Normal types, you can define a Distribution method for distributing the force over the geometry or FE entities. For more information on defining a Spatial field for a force distribution, see Define a spatially-distributed force with a formula field.
