How to give base excitation to any other location than to the fixed supports? As it can scope only to 'Fixed supports' in Acceleration.

Thanks in advance.

Hi,

Base excitation must applied on fixed support, displacement, remote displacement or body to ground spring.

But apart from Fixed support and displacement, there is no other boundary condition that can be scoped like remote displacement or body to ground spring.

Deepesh, remote displacement is a BC that works for Base Excitation as mentioned by Ashish above.

I don't know if a Body-to-Ground spring will be excited by Base Excitation, but if not, you can introduce a massless rigid body into your model to represent the ground. That body can have the Remote Displacement, and the springs can be converted to Body-to-Body.

remote displacement as boundary condition for base excitation. Is this a new change in versions post 2022 R1 ?
