Function to inject particles only once?
 

Hi,

Once a fluid flow field has been established, I want to inject some particles to see where do they go? The user interface in CFX-Pre(v11)allows to specify the particles to be injected in 'per second' basis. While I do not want to overload the solver and hence I want to inject some 100 particles just once.

How to do that? Do I need to define some user function using FORTRAN/CCL? I do not have any experience with it, please guide.

with very kind regards, KK
