ParaView/Visualizing PHASTA with SyncIO

Running Paraview on a viz Node

 portal1 $ vglconnect viz002
 viz002 $ soft add +paraview-5.2.0-gnu-ompi

Defining the PHASTA Input

There are two extensions:

pht -> POSIX files

phts -> SyncIO files

A Two Phase Case

An example phts file for a two phase, four process case using one syncio file is below.
