UDF about DPM injection
 

in my project my own DPM injection should be defined, should i choose which one between "file" and "group" as my injection type? can i define the paricles' release position one by one? (since no definetely correlation for the discrete particles). in udf,which macro can access a point's position? thanks for you looking into the post. regards.

Hello

You should made a file specifing not only x,y,z coordinates but also u,v,w,diameter,temperature,mass-flow, and injection name

the file should have the following form:

((x y z u v w diameter temperature mass-flow)name) ((# # # # # # # # #)injection0:1) ((# # # # # # # # #)injection0:2) .... .... .... ((# # # # # # # # #)injection0:n)

Now, the distribution of the particles should follow some sort of distribution for instant equal amoung of particles per area, uniform random distribution, or gaussian random distribution.
