Generate tracks' error for OpenMOC

User Support

Hi, there, when I use the track_generator to run openmoc,

track_generator = openmoc.TrackGenerator(openmoc_geometry, num_azim=128, azim_spacing=0.1)
track_generator.generateTracks()

the simulation crashed with the error below.

RuntimeError: Unable to allocate memory needed to generate Tracks.
...  Backtrace:
The total height and width of the Geometry must be 
... nonzero for
...  Track generation. Create a CellFill which is 
... filled by the 
... entire geometry and bounded by XPlanes and 
... YPlanes to enable 
... the Geometry to determine the total 
... width and height of the 
... model.

I just want to varificate the multiGroup cross section on my own geometry. The geometry looks like this:

reactor_xy
reactor_xy5000×5000 60 KB

my question is how can I fix this and get the openmoc results?

@KK_Lee This forum is for discussion of the OpenMC code, not OpenMOC. I would suggest sending a message to the OpenMOC user’s group.

Okay, I will try that, thank you sir.
