Installing and running Serpent

Running Serpent

Serpent is run from the Linux command line interface. The general syntax is:

sss2 INPUT [ options ]

Where INPUT is the input file name and the available options are:

-version	: print version information and exit
-replay	: run simulation using random number seed from a previous run
-his	: run only burnup history in coefficient calculation
-coe	: run only restarts in coefficient calculation
-plot	: stop after geometry plot
-checkvolumes N	: calculate Monte Carlo estimates for material volumes by sampling N random points in the geometry
-checkstl N M	: check for holes and errors in STL geometries by sampling M directions in N points
-mpi N	: run simulation in MPI mode using N parallel tasks
-omp N	: run simulation in OpenMP mode using N parallel threads
-disperse	: generate random particle or pebble distribution files for HTGR calculations
-rdep	: read binary depletion file from previous calculation and print new output according to inventory list
-tracks N	: draw N particle tracks in the geometry plots or invoke track plot animation
-comp MAT [ ID ]	: print standard material composition of listed material MAT that can be copy-pasted into the inputfile
-elem SYM DENS [ ID ]	: decomposes natural element identified by symbol SYM at density DENS into its constituent isotopes
-qp	: quick plot mode (ignore overlaps)
-nofatal	: ignore fatal errors

Most of the input options are self-explanatory, the rest are described below.
