Serpent - TRANSURANUS

Input files

Kytkin input file

Input file for the coupled calculation driver program Kytkin.

Notes:

  • Comment lines begin with #
  • Pins in Serpent are assumed to be given numeric ids.
  • Lists of pin numbers can be given as comma separated list (1,2,3), as range (1-3) or combination of both (1-3,6,8).
  • SLURM refers to running the calculation in an HPC environment with the SLURM job management system.
# Name of coupled calculation case. Your Serpent and TRANSURANUS input files need to have this same name followed by the file type description. Example input files:
# Serpent input file: casename.sss
# TRANSURANUS input file for first step (0) and first pin (1): casename.tuinput_0_1
# TRANSURANUS input file for other steps (n) and fifth pin (5): casename.tuinput_n_5

couplingname casename

# Timestamp to be printed in the output.

inputdate 2019-12-12

# Type of coupling in Serpent: 5 constant or 6 linear interpolation are supported.
# See Serpent multi-physics interface documentation for details: http://serpent.vtt.fi/mediawiki/index.php/Multi-physics_interface

couplingtype 6

# Type of radial divisions for power tallies in Serpent. Several entries can be given. Parameters: pin_ids division_type number_of_divisions
# pin_ids: List of the pin numbers for which the division applies to.
# division_type: 0 for the same division as in TU (old feature, not recommended), 1 for equal volume bins.
# number_of_divisions: define the number of radial bins (not given with division_type 0)
# Example for 10 equal volume bins in pins 1,2,3,4,9,10 and 20 equal volume bins in pins 5,6,7,8:

sssradtype 1-4,9,10 1 10
sssradtype 5-8 1 20

# File name for the Serpent coupling interface file. Used to feed coupled calculation data to Serpent. Kytkin creates this.

sssifcname casename.sssin

# Select startoption for Serpent:
# 0 Direct startup, set number of OpenMP tasks
# startoption 0 <NOMPTASKS>
# 1 SLURM reservation, options are taken from environment variables
# startoption 1
# 2 OpenMPI, set number of processes and OpenMP tasks
# startoption 2 <NPROCS> <NOMPTASKS>
# Example for OpenMPI with thee processes (e.g. computing nodes) and eight tasks (e.g. cores in a node) for each:

# Serpent ids (universums) of coupled fuel pins. Note: not all pins defined in the Serpent model need to be calculated in coupled mode.
