Attributes

id

Element identification number, (integer>0).

i_marker_id

The ID of I marker.

j_marker_id

The ID of J marker.

is_action_only

A Boolean variable.  Select from "TRUE" and "FALSE".

"TRUE": The element applies a force/torque on the I marker but no reaction on the J marker.

"FALSE": The element applies a force/torque on the J marker but no reaction on the J marker.

val

Modifies the magnitude of a constant valued force.

val_expression

Modifies the magnitude of the force vector as a function expression in the XML input file.

usrsub_fnc_name

Specifies an alternative name for the user subroutine SFOSUB.

Example

<Force_Scalar_TwoBody

  id             = "30101"
