Cylindrical_shell for pack_spheres()

tintin · June 15, 2023, 8:41pm

Hi everyone,
How to fill a cylindrical shell with openmc.model.triso.pack_spheres()?
For now, the only admitted regions are ‘rectangular prism, cylinder, sphere, and spherical shell’ (cf doc)
(by ‘cylindrical shell’, I mean the region between two co-axial ZCylinders, the ZPlane(z0=0.) and Zplane(z0=1.) for instance)
Thanks a lot!

Unfortunately right now it’s not possible. If you wanted to take a stab at implementing this though, it would only require changes to this class:

          class _Cylinder(_Container):
              """Cylindrical container in which to pack spheres.
          
          
    Parameters
              ----------
              length : float
                  Length of the cylindrical container.
              radius : float
                  Radius of the cylindrical container.
              axis : string
                  Axis along which the length of the cylinder is aligned.
              sphere_radius : float
                  Radius of spheres to be packed in container.
              center : Iterable of float
                  Cartesian coordinates of the center of the container. Default is
                  (0., 0., 0.)
          
          
    Attributes
              ----------

Ok, thanks @paulromano

Hi,
I’m facing the same issue, were you able to edit this to pack TRISOs in the region or make your own function to pack the spheres?
Thanks!
