Add option to PatternedMeshGenerator to define outer boundaries of patterned mesh

8

Refs idaholab#21634

## Reason Currently, PatternedMeshGenerator takes in boundary names for stitching input meshes into a lattice, but there is no option to define and set the outer boundaries of the resulting...

WIP: Griffin ABTR XS generation and steady-state analysis workflow

2

refs #386. Still needs testing to be added This model will be the starting point for an upcoming hands-on SFR training led by the Griffin team

## Model Description Steady-stage XS generation and eigenvalue calculation for ABTR SFR core. Runs natively with Griffin and runs MCC-3 in the background. Needs to run on HPC for most...

Add parameter in ReactorMeshParams to set block name in RGMB MG's based on region ID EEID

7

## Reason ## Design ## Impact refs #27673

### Motivation The Griffin team needs a way to define block names from RGMB mesh generators for each region ID, as lumping all blocks in the mesh into just two...

Fission site bounding box reporting when threshold fissionable site rejection sampling error is triggered

7

## Description #2916 fixed an error check that was previously not properly implemented in `IndependentSource::sample,` where the variables `n_accept` and `n_reject` are now properly defined as static variables. Previously, only...

## Reason Doing some more cleanup of Griffin, where I am removing the parameter `Mesh/EquivalentCoreMeshGenerator/max_axial_mesh_size`, whic can be inferred from another part of the input file. The removal of this...

Hung simulation when trying to load mesh with --distributed-mesh option
