problem on DEFINE_DPM_OUTPUT
 
Hi,

I am now working on a discrete phase flow and like to export the velocity magnitude of gas along each particle trajectory. It seems that using DEFINE_DPM_OUTPUT is the best way. However, when compiling the "Melting Index Along a Particle Trajectory" example in Fluent UDF user guide, I always met the compile errors, like "parse error", "structure reference not implemented", or "sprintf: undeclared variable", etc. Do you have any experience on it ? I really appreciate your info.

Thanks,

Xubin

Hi Xubin, Isn't it enough for your problem to activate the "Step by Step" Report Type in the menu "Particle Tracking"? Than you will receive a file with all particle positions and velocities. You can import these data into Excel.
