Giving an impulse input in Transient structural analysis

  How can we give an input force impulse of a particular magnitude of duration dt= x sec (like the one shown in figure)?

  Hi
  You can define a tabular force (use tabular data option) with that shape and duration:

    Ok. What to do if it is given as a sinusoidal function with a particular period?

      Hi
      You can create any tabular load (say in excel use sin function and any other function), then copy and paste it into the tabular force data in mechanical.

      Hope it is clear that we can copy and paste data into tabular data in mechanical.
      One can also use function instead of tabular for a load :
