chirp signal as a prescribed displacement

Please login with a confirmed email address before reporting spam

Hi everyone

Can anyone help me to add a prescribed displacement of a cantilever beam as a chirp signal ?.
I'm using 2D structural mechanics (plate) physics and time dependent study.
Thanks in advance...

COMSOL allows the user to type in mathematical expressions as inputs, so you can just type in the expression you want (presumably as a function of time) in the input field for the prescribed displacement. See COMSOL Multiphysics Reference Manual, version 5.2, Chapter 5 for more information on syntax.
Best regards,
Jeff
