4) YZ plane slice through the centroid.
Each window has a mesh plot with the "STL_mesh" variable, a Pseudocolor plot
with the "TALLY_TAG" variable, and the second, third, and fourth windows have
Contour plots with the "ERROR_TAG" variable. If the user has indicated to,
launch VisIt and load the session file.
Input:
______
geometry_file: h5m file
User supplied geometry file.
data_file: h5m or vtk file
User supplied data file.
args: Namespace
User supplied geometry file location, data file location, and
indication if the user wants images of the plot windows with a
timestamp and the session file saved and opened in VisIt.
Returns:
________
