Hi,
I am trying to generate the Ensight *.mpgXXX files (XXX is the particle time) for
a DPM steady flow/unsteady track . However I am getting the following message when I run 1 fluid-steady iteration :

iter  continuity  x-velocity  y-velocity  z-velocity     time/iter
  2201  3.8769e-04  2.3095e-06  2.4949e-09  3.1855e-06  0:00:02    1

Advancing DPM injections ....

Injecting 15 particle parcels with mass 4e-06
number tracked = 15
Injecting 15 particle parcels with mass 4e-06
number tracked = 30

number tracked = 30, escaped = 1
number tracked = 29, escaped = 2
number tracked = 27, escaped = 1
number tracked = 26, escaped = 1
number tracked = 25, escaped = 1

DPM Iteration ....
No history data to export for this time step.

 

In short : At the end there is no Ensight *.mpgXXX files generated

Any  clue how to solve this issue is very welcome.
The figure attached reproduces the windows of my setup.

I think you must reduce the particle time step size and number of time steps per DPM iteration, and solve many DPM iterations. You are exporting particle data only once per DPM iteration.
