e4476fc0b7 Delayed mpi4py import until the user clearly indicated intent to use a communicator (or they already have created one and thus have already imported it); corrected versionchanged doc statements to include comments about what changed; added stackoverflow reference 2021-10-01 09:21:41 -05:00

20c8043c1c (1) Made OpenMC load plots.xml upon initialization even if not in the plot runmode; (2) Made the finalize method clear plotting data; (3) allowed the openmc.lib and openmc.model package to call plot_geometry now that plots.xml would have been loaded 2021-09-30 15:15:58 -05:00

ad3a14fa3d Resolving comments from @paulromano. Namely, set the openmc.lib.Cell rotation and translations to be properties that can take iterables vice ndarrays. Also removed const declaration when not needed. Finally, revised code and tests so that we do not return a None for non-initialized cases. This would yield different behavior between translation and rotation and instead of leading to confusion I now simply always return a sensical ndarray of float values.That is no rotation is no longer None, but is now array([0., 0., 0.]). 2021-07-30 11:42:27 -05:00
