Hi,
My problem concerns with a square geometry with an oscillating lid.
I wanted to know how to give the boundary condition for a wall to oscillate.

Thank you in advance
Ameya

Hi

oscillating in translation or rotation or both ? and is it an imposed oscillation (force displacement ...'') Is the oscillation driving, or driven

If you have the answer to this I'l lexpect you will find the BC directly yourself ;)

Good luck

I do not know where to give the boundary condition in COMSOL since I am new to the software. I know 'what ' the boundary condition is ;\

Hi

then I can oly advice you to go step by step through some of the introduction videos on the web, and do some of the model library examples. But start one physics at the time, jumping straight into a CFD case, and in the same time learning all the buttons and twiggles of COMSOL is really ambituous
