Define a time-varying force with a formula field

In this example, a time-varying force that is defined with a formula field is applied to a flat rectangular plate.

Choose Home tab→Loads and Conditions group→Force .
In the Force dialog box, from the Type list, select Normal.
Select the geometry or FE entity to which the force will be applied.
Click and select from New Field→Formula .
In the Formula Field dialog box, from the Independent list, select Time.
In the Expressions box, enter an expression that defines how the force varies with respect to time.For example, suppose a force varies sinusoidally with an amplitude of 1000 N and a period of 4 sec. To create an expression for this force, enter:1000*sin(90[degrees]*ug_var(“time”)/1[sec])
Click Accept Edit .The expression is added to the Expressions list.
Click OK in all dialog boxes.
