[Paraview] ParaView 5.0.0 for Windows x64 fails to open EnSight Gold files

Mon Feb 29 03:04:36 EST 2016

Another "experimental data". I was able to load this big case in ParaView
viat the CGNS format. It was neccesary to select CGNS 3.0 and HDF5 options
in CFX Converter. But when I apply the Extract Block filter I see no any
boundaries, only fluid domain (that is displayed OK). So CGNS format is not
a wayout...
