Steady plot3d binary files are easily readable in Paraview, But when I load 2D unsteady binary grid file and solution plot3d file (solution output at all time steps is written in a single solution file), It doesn’t load with respect to time. data is loaded at all time steps as static data shown below.

Please suggest to resolve it. Any suggestion will be valuable.

Here is an example of a supported .p3d file with time.

```
{
    "byte-order" : "big",
    "precision" : 32,
    "multi-grid" : false,
    "format" : "binary",
    "language" : "C",
    "blanking" : false,
    "2D" : false,
    "functions": [110, 200, 201],
    "R" : 8.314,
    "gamma" : 1.4,
    "filenames" : [
	{ "time" : 3.5, "xyz" : "combxyz.bin", "q" : "combq.bin"},
	{ "time" : 4.5, "xyz" : "bluntfinxyz.bin", "q" : "bluntfinq.bin"}
    ]
}
```

Thank You,  
Actually, CFL3D produce all time steps in a single file. However, I obtained binary plot3d output files at all successively time steps by restarting the simulation and use this .p3d file. But it is little time consuming.

Our reader probably does not support this formalism and would need to be improved.
