dynamic mesh velocity specified for each face

baghfay · February 13, 2019, 13:17

under DEFINE_CG_MOTION
i loop through the faces trying to give each face a specific velocity so the wall faces will move diffrently but after compiling and run the case i always get the wall to move at fixed velocity
any advice how to correct the UDF so each face moves diffrently

begin_f_loop(f,t)
{
i = i++;
vel[1]= i*dtime;
}
end_f_loop(f,t)

regards

is it possible, what do you think?
take a list of paper and move its part with different velocities

best regards

dear Alexander
thanks for your reply
i am new in using UDF as well as in working with dynamic mesh
however for my basic understanding the answer is yes otherways how can we model heart movement or expanding membranes for example
i would like if you advise me how this kind of moving walls can be modeled and where i can find similar examples
thanks
