Investigate Stage 2 breach geometry for Macchione model type
The plot for the Macchione model starts out with a correctly formed initial breach shape, but displays unexpected results as the breach floor reaches the fixed foundation.
As seen in the following plot, the initial triangular breach is not limited by the foundation (thus creating a trapezoid), but instead results in vertical drops that stretch down to the point of the initial triangle geometry.
More investigation is needed to determine whether this is a display issue (e.g. missing data points or existing data points improperly connected), or whether there are deeper issues in the model type's geometry expression.
