Hi Code_Saturne users and developers,

I work on the pulverized coal combustion example case following the example manual. Section 8.1 of the manual is on outputting the particle trajectories. After the case is run, we have PARTICLE.case and particles.geo.00001, particles.geo.00002, particles.geo.00003, ... in the postprocessing direction.
Then, how do we plot the particle trajectories in ParaView? Thank you.

Hello,

I'm not sure ParaView can directly plot trajectories, at least in the Code_Saturne case (most particle-oriented formats such as h5part or associated viewers assume a constant number of particles). You can activate a dedicated trajectory writer an associate a trajectory mesh (a succession of segments) in the Code_Saturne GUI, so check this...

Hi Yvan,

Thank you. After creating a trajectory writer and associating a trajectory mesh to it (see attached pictures), I should have trajectory files (trajectories.00001, trajectories.00002, trajectories.00003, ...) generated in the postprocessing directory, right? But, I don't see such files being generated. I use v4.0.5 on Ubuntu. Thank you for helps.

Hello,

You also need to set the type of the trajectory writer to "trajectory" (and not particles). The type is actually more important than the name.

Thanks. I get trajectories now.
