Doubt in fluid domain visualization

[NM1293]

Hello,

I am attempting to execute the code for fluid visualization available at https://flow.byu.edu/FLOWUnsteady/examples/rotorhover-fdom/.

Previously, I followed the "variable fidelity" tutorial https://flow.byu.edu/FLOWUnsteady/examples/rotorhover-aero/, utilizing mid-low fidelity, with the intention of utilizing these outcomes to conduct the fluid domain visualization.

However, I have encountered some uncertainties regarding the fluid visualization code. Upon examining the results obtained from the execution of the "variable fidelity" tutorial, I discovered numerous files labeled "rotorhover-example_pfield.TIMESTEP.h5/.xmf" and "rotorhover-example_staticpfield.TIMESTEP.h5/.xmf", where TIMESTEP indicates the associated time step. Hence, if my understanding is correct, the variables "pfield_prefix" and "staticpfield_prefix" in the "fluid domain" code should correspondingly be set to "rotorhover-example_pfield" and "rotorhover-example_staticpfield", while the variable "nums" should be equivalent to the total number of time steps of the simulation for which I wish to visualize the fluid domain, minus 1.

Upon completion, I only obtain a single .h5 and a single .xmf file.

Is this correct?

Should I be able to open these files with ParaView? I attempted to do so, but encountered difficulties in visualization.

The code I am using is attached.

Thank you for your assistance.
