Hi,
If you want to define a Force versus Time you have to use an Array of Discrete Values obtained from the defined Force Curve.
For 2D and 3D Applications Ansys allows to use 2D or 3D Arrays with :
*DIM, Force, Array, Imax, Jmax, Kmax : to define an Array Parameter and its Dimensions.
Force can be Defined with *SET Command which Assigns user Defined Values.
Imax=n and Jmax=Kmax=1 : Corresponds to Force(t) Time History Forcing function.
The Third Dimension (Jmax=m and Kmax=p) can be useful to Model Fluid Flows with Specifying the Function as a Table Array
Parameter with Force and Time Values in a Non Linear Solution.
