solidBodyMotionFunction for a decelerating object

ShinyRiver · September 12, 2016, 08:35

Dear All,

I have recently installed foam-extent 3.2 and tried with the "moving cylinder" tutorial successfully. I use "translation" as the "solidBodyMotionFunction".

QUESTION:

If I want to have a time-dependent velocity of the immeresed body, let say acceleration or deceleration, how I can set it? I know if I want to have ACCELERATION from zero to the fixed value of the velocity in a certain time, I can set the "rampTime" equal to that time interval, right? But how I can set a decelerating movement?

Many thanks in advance,
ShinyRiver
