Hi,

I have the CFX simulated steady wind field in a tube. And would like to have some particle trajectory plot based on this steady wind field.

Is CFX Post is capable to do that? I have produce a very nice picture for streamline but cannot find the option for particle trajectory.

Should I dump out the result and write my own code to do that?

Thanks Jim

choose the option "track file", and then choose the *.trk file as the track file.

Jim, are you using CFX5 of CFX4 ? at present there is no capability in CFX5.5.1 for particle tracking. CFX5.6 which the beta release should be out shortly will have particle tracking embedded into it. Version 4 of the software does include particle tracking, however I'm not sure if you can just run the particle tracking by itself (you should be able to but I'm not 100%), so you may need to do a restart on your existing run and start the particle tracking. The files that the particle tracking creates can then be read into post as a polyline. This can be tedious to read in so I'd reccomend setting up a little perl script session file to do this. Good luck Bob

Bob,

I am using CFX5.5. Thanks for your advice.

Jim

Try talking with you support person at CFX, they will advise you as to you best next step ie wait for 5.6 or trying CFX4 ? Bob
