MCNP→TRIPOLI-4 geometry converter

Published on 2 April 2021

​t4_geom_convert is a tool that converts geometries from the MCNP input format into the TRIPOLI-4® format. It is capable to handle most of the idiomatic MCNP constructs, such as universes, lattices, macro-bodies and affine coordinate transformations. It also converts isotopic compositions and boundary conditions.

This image shows a cut of the C-lite model of the ITER fusion reactor . The MCNP geometry (courtesy of Jean-Charles Jaboulay) was converted to the TRIPOLI-4 format by t4_geom_convert. The plot was made with T4G.

​t4_geom_convert is free software! It is distributed under the terms of the GNU General Public License, version 3. More details and installation instructions are available on GitHub.

The development of t4_geom_convert has been partially supported by the Eurofusion consortium.
