# NOTE: #
# 1. Not all output is defined in the DS_HDF5.xml, please add new #
# new one to the system wide definition file #
# <DAMASK_ROOT>/lib/damask/DS_HDF5.xml #
# or specify your own when initializing HDF5 class #
# 2. Somehow the point cloud structure cannot be properly handled #
# by Xdmf, which is a descriptive wrapper for visualizing HDF5 #
# using Paraview. The current solution is using cell structured #
# HDF5 so that Xdmf can describe the data shape as a rectangular #
# mesh rather than polyvertex. #
# TODO: #
# 1. remove the <ASCII_TABLE>._tmp file, basically need a way to #
# just load data from ASCII table. #
# 2. a progress monitor when transferring data from ASCII table #
# to HDF5. #
# 3. a more flexible way handle the data structure rather than a #
# xml file. #
