How to implement a numerical scheme by using UDF?
Hi everybody,
I want to simulate the migration process of droplets stick in a flow chamber. I've worked out a numerical scheme for individual droplet motion, the motion equation is derived from Newton's Second Law and is coupled with the velocity field of the fluid. However, it seems Fluent does not provide such fluid-structure interaction package for pariticle motion so I want to write a UDF code. Primrary difficulty of this implementation is that the numerical scheme needs to solve several difference equations for the whole domain in each time step and I have no idea how to arrange this scenario. Is there any precedents of this situation? Can anybody figure out a way for me? Thanks in advance.
