two amplitudes

how to impose two amplitudes simultaneously to the boundary conditions

*BOUNDARY, AMPLITUDE=<amp1>
...
*BOUNDARY, AMPLITUDE=<amp2>
...

etc etc

thank you for your help, but I want to have two amplitudes simultaneously in the same step (two displacement at the same time)
thanks

If the displacement BC's are being applied to two different parts (or two instances of the same part) in the same step then it should work just as Drej suggested.

If the amplitudes are supposed to applied to the same part in different steps then that will work too. Just edit the BC in the appropriate step and change the amplitude.

If you want to apply two displacement amplitudes to the same part instance in the same step I am not sure you can, or why you would want to.

thank you for your help.
yes i want to apply Two boundary conditions (displacement + rotation) amplitudes to the same part instance in the same step.
I tried and it works using "velocity / Angular velocity" (without amplitudes)..
but it does not work with "Displacement / Rotation" amplitudes.
Thanks

Post your input deck, specifically the *STEP that you're using for this.
