tenichols19 is on a distinguished road
When trying to create a blockmesh so that I can create a mesh using snappyhexmesh I run into an issue.
First I start with an existing case file (motorbike) and then I make changes to the blockMeshDict. Which can be seen here
Code:
FoamFile
{
    version     2.0;
    format      ascii;
    class       dictionary;
    object      blockMeshDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

convertToMeters 1;

vertices
(
    (-1 -1 -1)
    (16 -1 -1)
    (16 4 -1)
    (-1 4 -1)
    (-1 -1 4)
    (16 -1 4)
    (16 4 4)
    (-1 4 4)
);

blocks
(
    hex (0 1 2 3 4 5 6 7) (51 15 15) simpleGrading (1 1 1)
);

edges           
(
);

patches         
(
    patch minX
    (
        (0 4 7 3)
    )
    patch maxX
    (
        (2 6 5 1)
    )
    patch minY
    (
        (1 5 4 0)
    )
    patch maxY 
    (
        (3 7 6 2)
    )
    patch minZ
    (
        (0 3 2 1)
    )
    patch maxZ
    (
        (4 5 6 7)
    )
);

mergePatchPairs 
(
);
So pretty much all I did was change the dimensions of the cube. I run blockMesh and the mesh checks out ok as seen here.
Code:

and I checked the mesh here

I wanted to make sure my stl file would fit within my new mesh so I ran paraFoam. Paraview opened but when I clicked on the mesh paraview shutdown and this error appeared.
Code:
taylor@taylor-Precision-T1700:~/OpenFOAM/taylor-7/run/ten$ paraFoam
Created temporary 'ten.OpenFOAM'
I/O    : uncollated


--> FOAM FATAL IO ERROR: 
Cannot find patchField entry for minX

file: /home/taylor/OpenFOAM/taylor-7/run/ten/0/p.boundaryField from line 26 to line 49.

    From function void Foam::GeometricField<Type, PatchField, GeoMesh>::Boundary::readField(const Foam::DimensionedField<TypeR, GeoMesh>&, const Foam::dictionary&) [with Type = double; PatchField = Foam::fvPatchField; GeoMesh = Foam::volMesh]
    in file /home/ubuntu/OpenFOAM/OpenFOAM-7/src/OpenFOAM/lnInclude/GeometricBoundaryField.C at line 191.

FOAM exiting

Segmentation fault (core dumped)

It appears that it is accessing the initial conditions files but that doesn't make since to me because this should'nt have anything to do with the initial p or U.

Any help would be greatly appreciated!
