Compiling the source code

Compiler options

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  : print standard material composition of listed material mat that can be copy-pasted into the inputfile
-elem sym dens  : 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.
