Number of Timestep in Export Particle Data

      Hello,

      I have a question about the function of exporting the particle history data to Ensight. I am doing the 1-way particle tracking. When I export the particle history data, particles did move in the first few timesteps, and then the particle freeze for the later saved timestep.

      Let's say we are saving only ten timestep. how does the export function define/choose the particle timestep that was saved to Ensight? It seems to me that it saves the snapshots that are already out of my defined maximum timestep.

      Are you running steady state flow with steady particle tracking?

      Yes, it is a steady state simulation of flow field and then the particle is tracked with post-processing. There is no interaction with continuous field.

      Okay so you are exporting time snapshots of the particle tracks into Ansys EnSight. The more snapshots the bigger the file the more you might see in EnSight if you are interested in qualitativlvey better results. This is number of particle time steps per trajectory!
