Unable to reproduce results of the SFR pincell multiphysics tutorial

[nancysemwal]

I am following the SFR pincell multiphysics tutorial. But I am unable to reproduce the plots shown at the end of the tutorial. I am viewing the results from the openmc_out.e file in Paraview.

This is what my cell_temperature plot looks like. You can see the I'm not getting any temperature variation -

These are what my nek_temp & moose solid temperature plots look like respectively. These are also wrong as seen in the plot legend (since maximum temperature is 1100 K for me while its 736.3 K in the tutorial) -

How can I diagnose whats wrong with the simulation from a Physics perspective? I am a computer science engineer so physics is not my strong suit. I have run the same commands given in the tutorial and used the same input files without changing any parameter. Also I got finished with exit code 0 message at the end of the simulation so I understand nothing went wrong.

I am on the devel branch of the repository and the last commit on this was around 9 Nov, 2024 (checked using git log). I checked and no updates have happened to the tutorial since then.

How do I move further?

Hi Nancy,

In order to view the solution on each Picard iteration, you need to toggle through the timesteps with the icon shown below. Because you are viewing time step 0, you are only seeing the initial conditions (not the actual converged solve).

Please let me know if this works for you!
