csg2csg 0.0.30

Convert CSG geometry into different formats

csg2csg

A tool to translate common Monte Carlo geometry formats between each other.

How to use

Right now the code is petty rough.

Install using pip pip3 install csg2csg --user

Run from the terminal with csg2csg -i filename -f format where filename is the input filename and format is the file format of the input file. Options for the file format include several neutronics codes [mcnp, serpent, openmc, phits, fluka] each is at a different level of completeness.

The default is to attempt to translate the input file into all neutronics codes but users can specify which codes with the -o flag.

To see all the run options type csg2csg -h in the terminal

Caveats

Several! Right now only MCNP can be read, and then written to MCNP Serpent and OpenMC. When the file can be read only a subset of MCNP surfaces can be read

MCNP Surfaces Supported

• P,PX,PY,PZ
• S SO SX SY SZ
• CX CY CZ C/X C/Y C/Z
• SQ
• GQ
• KX, KY, KZ
• TX TY TZ
• Macrobodies - RPP, SPH and RCC
• X, Y, Z - one and two coefficent only

MCNP Surfaces Not Yet Supported

• X, Y, Z - three coefficient
• Macrobodies - BOX, RHP, HEX, REC, TRC, ELL, WEB, ARB

Tranforms

• Are read and interpretted, but nothing is done with them, in the future codes that support cell transformations will use it, but right now MCNP is the only code that does surface transformations
