I want to define an impulse function in ANSYS apdl. I could not find heaviside function in function editor to build it (H(t-t0)-H(t-t1)). How I can build this function in ANSYS apdl, easily?

If your intention is to apply a time-varying load, define a table array using MAPDL, for example:
impulse(1,1)=0,0,1,1 ! VALUES OF EXCITATION
impulse(1,0)=0,1,1.0001,2 ! CORRESPONDING VALUES OF TIME
*vplot,impulse(1,0),impulse(1,1) ! PLOT FUNCTION TO CHECK, .png WILL APPEAR IN MECH DIRECTORY
acel,,,%impulse% ! EXAMPLE: APPLY ACCELERATION ON Z DIRECTION USING IMPULSE TABLE ARRAY
Hope this helps!
