According to the manual FMESH only supports Cartesian or cylindrical geometry has there been any update to this or is that it?
FMESH is a feature in the Monte Carlo N-Particle (MCNP) computer code that allows for the creation of a fine mesh tally on a specified surface or volume. It is used to calculate the flux of particles across a specific region of interest in a simulation.
Yes, FMESH does support spherical geometry in MCNP. This means that the user can specify a spherical surface or volume as the region of interest for the fine mesh tally.
FMESH and TMESH are both tallies in MCNP, but they differ in their purpose. FMESH is used to calculate the flux of particles across a specified region, while TMESH is used to calculate the average value of a physical quantity within a specified region.
Yes, FMESH and TMESH can be used together in MCNP. This allows for a more comprehensive analysis of the simulation results, as both tallies provide different types of information.
Yes, there are some limitations to using spherical geometry with the TMESH tally in FMESH. The spherical region of interest must be completely contained within the mesh grid, and the mesh size must be smaller than the radius of the sphere. Additionally, the spherical region cannot intersect with other regions of interest or boundaries in the simulation.
