When simulate movement of particles under a complex gridding system such unstructered or multi-block structured grid by lagrange-euler method, to located the particle to get the local velocity for the calcution of drag force of particle is very important. Often, in a rectangular gridding, it is very easy to complete the task, but for a complex gridding, how to do it. Thanks in advance
