Injecting Particles
Dear all,
I want to solve a problem in Fluent regarding injection of droplets from a surface. In my injection surface I have about 100 cells and it seems that when I start simulation it only inject 100 particles (equal to number of surface cell). Does anyone know how can I increase the number of particles? I think there should be something in Define>Injections> set> File But I don't know how should I write the File for injection. I would be glad if anyone can solve the problem. Cheers, Pejman |
This is a sample of injection file.
x y z u v w diameter temperature mass-flow )
( ( -1.7546E-02 -4.0000E-03 -1.7546E-02 0.0000E+00 0.0000E+00 0.0000E+00 1.0000E-06 2.0000E+01 0.0000E+00 ) ) ( ( 0.0000E+00 -4.0000E-03 -1.7546E-02 0.0000E+00 0.0000E+00 0.0000E+00 1.0000E-06 2.0000E+01 0.0000E+00 ) ) ( ( 1.7546E-02 -4.0000E-03 -1.7546E-02 0.0000E+00 0.0000E+00 0.0000E+00 1.0000E-06 2.0000E+01 0.0000E+00 ) ) You can save this file as TXT or inj file. It should be worked |
Dear Zhang,
Thanks for your help. As I got the impression it will produce an injection point. Do u have any idea how can I make the same file for surface injection. My surface is something like this: x=1, 4<y<5, z=0 Thanks Quote:

each line is one particle,
each line is on particle, that information contains x y z position, uvw velocity, density,. diameter, ......
you can edit how many particles you want, just organize them(differnt position) together line by line. |
