GM All,  
I am trying to have two blocks of data (mesh and solution) in a XML .vtu format as provided below. The Paraview executable says that a reader for this program cannot be founds and gives a list of readers. However none contain xml. Please help:

Information about the mesh : each block has 2 hexahedras. The 2 hexs share 4 nodes.  
Thank you  
Ravi

Simplified to one block →

\<?xml version="1.0"?\> 10 0 0 11 0 0 11 1 0 10 1 0 10 0 1 11 0 1 11 1 1 10 1 1 14 0 0 14 1 0 14 0 1 14 1 1 0 1 2 3 4 5 6 7 1 8 9 2 5 10 11 6 8 16 12 12 

```
</MultiBlockDataSet>

```
