Filling Fraction

Problem Background

This is a module designed to set up various AMR meshes with different filling fractions and different branching ratios (or number of children of each grid). The test problem uses a filling fraction of .25 and a branching ratio of 1. In addition each single child is centered inside of the parent mesh to avoid different machines having different random placements. When running on more than 1 processor - these grids are decomposed into multiple grids. The module currently assigns the density to match the AMR level so that pseudocolor plots of density will track whether or not the module is still working. The module advects the entire solution a few steps diagonally.

Reason for Test

This module was designed to perform scaling tests.

Results

The new chombo can be verified by looking at the magnitude of the density.
