VOF: Moving Body
 

Hi all,

I require to simulate a moving 'bump' on the base of a simple 2d rectangular geometry consisting of water and air in FLUENT. For various reasons I cannot simply flow the water over the bump I require the bump itself to move through the water with a constant velocity in 1 direction (x).

Could anyone enlighten me about how I would go about simulating this? Or point me to any tutorials that would help me learn how to do so?

Thanks in advance.

Should I use a sliding/dynamic mesh? or is it simpler than that? Can I use multiple reference frames?
