This repository contains example problems that demonstrate various DASSH features and capabilities. More problems, demonstrating more capabilities, will be added in the future.
Example 1:
Single-assembly problem with adiabatic radial boundary condition.
This problem demonstrates:
-
Basic input file structure and requirements
-
Connection between DASSH and ARC-produced binary files
-
Input/output unit specification
-
Visualization integrated as a part of DASSH execution
Example 2:
37-assembly problem with flowing inter-assembly gap coolant.
Demonstrates:
-
Specification of material properties
-
Dumping detailed temperature data to CSVs
-
Multi-assembly problem location and boundary condition assignment
-
Plotting separately after DASSH execution
Example 3:
Single-assembly problem on EBR-II instrumented sub-assembly XX09 compared with measured data.
Demonstrates:
-
Use of user-specified power distribution
-
Double-ducted assembly setup
-
Comparison of DASSH results with measured data
Example 4:
Optimize coolant flow orificing on system from Example-2 to minimize peak fuel centerline temperature.
Demonstrates:
-
DASSH coolant flow orificing optimization algorithm\
