Default Rising bubble problem
Posts: n/a
Hello all...

i am trying to simulate a bubble rising in a vertical pipe due to density difference.

however, i havent found a good tutorial on this and after i started out on my own. i am faced with the following problems

how do i define the domain interfaces ? do i have to? or will it automatically create one when writing the .def file ?

also, how do i do mesh adaption here since the bubble deforms and also rises..??

i have uploaded the meshes for the pipe and bubble into cfx pre separately, is this a correct method or should i have only a single geometry+mesh ?
