I am having difficulty loading a set of vtk files in Paraview.

Attached is the matlab code for the file and two vtk output files.  
[time\_1.vtk](https://discourse.paraview.org/uploads/short-url/uGaGbmOzJqF066Vm0Iiim7zsfid.vtk) (236.2 KB)  
[time\_100.vtk](https://discourse.paraview.org/uploads/short-url/ewsmR7MtLLZVzPTR8VJpq1JSvw9.vtk) (236.2 KB)  
[write\_vtk\_grid\_values.m](https://discourse.paraview.org/uploads/short-url/pxfY8SyBurYdncA3LBVapiHXh1k.m) (1.8 KB)

There some issues with the files.

1. Line 5 . Remove quote ’
2. Lines 4103 4105 are

```auto
POINT_DATA 4096
SCALARS CONfloat 1
fLOOKUP_TABLEdefault

```

they should be

```auto
POINT_DATA 4096
SCALARS CON float 1
LOOKUP_TABLE default

```
