My simulation is a Steady with Unsteady DPM.
I'm running into an issue where I am not able to figure out how to load Steady simulation data and Unsteady particle data from Fluent into EnSight at the same time.
Following steps from
If from Fluent I perform Export > Solution Data into EnSight Case Gold, I get the Steady Solution Data that imports into EnSight just fine.
If from Fluent I perform Export > Particle History Data into Ensight and specifiy the previous .encas file, it creates the .new encas file but when loaded into EnSight, it only has the last time step.
The only way I'm able to get all the timesteps in an .encas file is if I do it through Export> During Calculation > Particle History Data. That get's saved into a new .encas file and when loaded, has all the time steps for particle data but it's missing all solution data.
Export> During Calculation > Solution Data is greyed out for Steady state.
I tried saving my solution data into an EnSight Case Gold file, and then rerunning the fluent simulation so the Export>During Calculation> Particle History Data points to the saved .encas solution data file but when I try to open the resulting .new file, it throws up a bunch of errors.
What am I missing? How do I import steady solution data AND unsteady particle data with all the time steps into EnCase into the same Case 1?

The second and third method you mentioned should import the unsteady particle data for steady simulation.
For the second method, you should have the particle history file in the directory where the .encas file is saved. In the edit panel, you will get option to specify the number of iterations for which the data is to be saved. You can specify a non-zero vaule and data will be exported for that many time steps. Please refer to the image below.
It will be really helpful if you can share the error message you are getting, to debug the issue related to the 3rd approach.
