According to the manual FMESH only supports Cartesian or cylindrical geometry has there been any update to this or is that it?
FMESH in MCNP does not support spherical geometry; it is limited to Cartesian and cylindrical geometries as per the official manual. Users have confirmed this limitation while utilizing the TMESH tally. There have been no updates or changes to this functionality in the current version of MCNP. For those needing spherical geometry capabilities, alternative methods or tools must be considered.
PREREQUISITESResearchers and engineers in the field of computational physics, specifically those using MCNP for radiation transport simulations and needing to understand geometry limitations.
