Can some one check the validity of the injection file
 
1 Attachment(s)
Hello I have been trying to insert some particles via the discrete phase in fluent hence used a script to feed in the particles.
There are thousands of such but i made a file with only 4 just to see if its working.
When i try to use list function to see if its reading it right in the dialogue box i get this
Quote:

Particle streams from injection-0:
STREAM ...........................INITIAL VALUES...........................
NO TYP (X) (Y) (Z) (U) (V) (W) (T) (DIAM) (MFLOW)
further clicking list gives 2 additional message after this
Quote:

ERROR reading particle 0 for injection: injection-0.
4 particles not found in injection injection-0
I have attached the text file for the script. Please can any one see what mistake am i doing? and if possible could any good samaritan fix it and run to see if the injection is working or not.
I would be really grateful for this since i am working on a research and am stuck in this issue for a long time.
Help will be really appreciated.

Remove the first line of the file which states the variables of the particle injection. Fluent is trying to read this line as an injection and is receiving strings where real numbers are expected.

thank you i did that too before but i used to get
Quote:

4 particles not found in injection injection-0
hence i added the first part.
Can you just feed it into a system to see if its working in your end ?

I've tested the injection file (without the first line) in a simple cube flow cell and the particles are injected and tracked as expected. There must be an error somewhere else in your model setup.

Thank you very much for this. I have been obcessed that there has been some error in my scripting the data. Now i know problem is elsewhere.

Hi guys,

I'm stucked on the same problem, same error message...

Did you figure out where the problem is/was ?


Thanks

It means that the coordinates that you give (or at least the one that Fluent reads) are outside of your fluid domain.
