Hi Mehdi,

If your intention is to apply a time-varying load, define a table array using MAPDL, for example:

*dim,impulse,table,4

impulse(1,1)=0,0,1,1 ! VALUES OF EXCITATION

impulse(1,0)=0,1,1.0001,2 ! CORRESPONDING VALUES OF TIME

/show,png

*vplot,impulse(1,0),impulse(1,1) ! PLOT FUNCTION TO CHECK, .png WILL APPEAR IN MECH DIRECTORY

/show,close

acel,,,%impulse% ! EXAMPLE: APPLY ACCELERATION ON Z DIRECTION USING IMPULSE TABLE ARRAY

Hope this helps!
