EXPERIMENTAL -- DO NOT USE THIS CAPABILITY/CONCEPT FOR PRODUCTION WORK
This is a test of an experimental capability to output only the transient
data to an exodus file. Eventually there will be a link between the
transient file and the file containing the mesh data. For now, we are
only writing the transient data and verifying that the file has sufficient
data to be understood by some of the seacas utilities.
One of the ultimate goals is to make per-timestep output of results
data faster since do not need the mesh definition bulk data
(coordinates, connectivty, ...) for each step
