8. Test Report¶
This section presents the verification of the requirements described in Requirements.
A test suite is generated based on a small SFR-like reactor model included in the ARMI
framework. The make-fixture-suite entry point to the dif3ddemo application
starts from that basis and builds a matrix of cases by modifying the relevant user
settings to cover all required features. Cases included in the matrix include:
Real |
Adjoint |
Real and Adjoint |

This test suite will be referred to in the verification of several requirements below.
8.1. Input¶
Requirement: Write valid DIF3D input fil... (R-write-input)
Verification:
The unit test testWriteInput()
writes an input from a sample case and compares it line-for-line with an included reference
input that has been determined to be valid.
8.2. Geometry¶
Requirement: Support 3-D hexagonal geome... (R-geom-types)
Verification:
This requirement is verified by running the make-fixture-suite entry point.
8.3. Spatial Approximation¶
Requirement: Support nodal and finite-di... (R-spatial-approx)
Verification:
This requirement is verified by running the make-fixture-suite entry point.
8.4. Solver Modes¶
Requirement: Support real and adjoint ca... (R-solver-modes)
Verification:
This requirement is verified by running the make-fixture-suite entry point.
8.5. Execution¶
Requirement: Execute a given DIF3D execu... (R-execute)
Verification:
This requirement is verified by running the make-fixture-suite entry point.
8.6. Output¶
Requirement: Read DIF3D output informati... (R-read-output)
Verification:
8.6.1. Keff¶
The output file lists
0 OUTER ITERATIONS COMPLETED AT ITERATION 19, ITERATIONS HAVE CONVERGED
0 K-EFFECTIVE = 1.00830171984
The unit test test_readKeff()
confirms this.
8.6.2. Total and Peak Flux¶
Table says:
REGION ZONE ZONE VOLUME TOTAL FLUX PEAK FLUX (1) TOTAL FAST FLUX PEAK FAST FLUX(1)

The unit test
test_readTotalFlux()
confirms the total flux is read correctly into b.p.flux. The
test_readPeakFlux()
confirms that the peak is read correctly.
8.6.3. Multigroup Flux¶
