The Force/Torque PropertyManager applies forces, moments, or torques with uniform distribution to faces, edges, reference points, vertices and beams in any direction for use in structural studies.
Type
Sets the type of force to apply. To apply force or moment to beams, see the topic Force/Torque PropertyManager (for Beams).

Force 


Torque 



 If you choose Force and select Normal, you can select faces and shell edges.
 If you choose Force and select Selected direction, you can select faces, edges, vertices, or reference points for force. The reference points must lie within the model’s boundary.
 If you choose Torque, you can select faces only.


Face, Edge, Plane, Axis for Direction 
Select an entity to specify the direction of the selected load. Valid entities depend on the load type as follows:
 If you rightclick External Loads and select Force, you can select a face, edge, plane or axis for direction.
 If you rightclick External Loads and select Torque, you can select a reference axis, an edge, or a cylindrical face.
In an assembly, you can use reference geometry from the assembly or the components (parts and subassemblies) of the assembly.


Units 
Sets the units that will be used to enter numerical values of the force/moment/torque. Available units are: SI, English (IPS), and Metric (G).

Force/Normal Force/Torque
Sets values for the force components, normal force, or torque.
Variation with Time
For linear and nonlinear dynamic studies, you can define a timedependent force.

Linear 
Uses a default linear time curve which passes through the points (0,0) and (t_{end}, P_{value}). Where P_{value} is the pressure specified in the Pressure value box and t_{end} is the End time specified on the Solution tab of the Nonlinear dialog box. 

Curve 
Uses a userdefined time curve. Click Edit to define or import a time curve. The pressure at any time is calculated by multiplying the pressure value specified above by the Y value of the time curve. 

Graph 
Displays the actual timedependent pressure. 
Nonuniform Distribution
Sets options for nonuniform force applied to faces or shell edges.
Check the component's box to specify nonuniform distribution.

Select a Coordinate System 
Select a coordinate system to define the nonuniform force.


Equation Coefficients 
Sets the polynomial coefficients which describe the spatial variation of the force in the selected coordinate system. 
When using
Equation Coefficients, the coefficients should be specified based on the units of X and Y as shown in the following table:
Selected Unit System 
Units of X and Y 
Units of "Value"

in (inch) 
lb (pounds) 
Metric (G)

kgf (Kilogram force) 
Symbol Settings
Sets the color and size of force/torque symbols

Edit color 
Select a color for the pressure symbols from the color palette. 

Symbol size 
Use the spin arrows to change the size of the pressure symbols. 

Show preview 
Turns on/off the display of pressure symbols. 
Notes:
The nonuniform force distribution is defined by a reference coordinate system and the associated coefficients of a secondorder polynomial.
F(X,Y) = A + B*X + C*Y + D*X*Y + E*X^2 + F*Y^2
Where:
F(X,Y) = relative magnitude of force applied at a point with coordinates x and y in the selected coordinate system
X, Y = coordinates of the point relative to the selected coordinate system
A, B, C, D, E, and F are polynomial coefficients
* indicates multiplication
The value you enter in the force value field is the force actually applied to the selected entities, if the force doesn't reverse direction on the geometric entities to which it is applied. If the force reverses direction along a geometric entity (face or edge), the applied force value is equal to the summation of the absolute values of the forces applied to all nodes on the face or edge.
Contrary to the application of variable pressure, the A, B, C, D, E, and F polynomial coefficients are only used to define the relative distribution of the force. Multiplying all the coefficients by an arbitrary value, will not change the distribution or the intensity of the force.
