Hi,

Wondering if it is possible to set up 2 independent velocity boundary conditions.

For a simple case with blockMesh of:
vertices
(
(0 0 0) //0
(2 0 0) //1
(2 2 0) //2
(0 2 0) //3
(0 0 2) //4
(2 0 2) //5
(2 2 2) //6
(0 2 2) //7
);

Usually the inlet will be defined in one patch of say (0 4 7 3).

Is it possible to create an addition patch for a different velocity profile without causing an error?

For example, I tried with the addition of vertices:
vertices
(
(0 0 0) //0
(2 0 0) //1
(2 2 0) //2
(0 2 0) //3
(0 0 2) //4
(2 0 2) //5
(2 2 2) //6
(0 2 2) //7
(2 0 1) //8
(0 0 1) //9
);

And in the blockMeshDict:

the block section:
blocks
(
hex (0 1 2 3 4 5 6 7 8 9) (10 10 10) simpleGrading (1 1 1)
);
the boundary for the inlet will change:
inlet1
{
type patch;
faces
(
(0 4 8 9)
);
}
inlet2
{
type patch;
faces
(
(9 8 7 3)
);
}

This is the general idea I had, does it even make sense?

The problem is, when I tried blockMesh, I encountered an error saying:
--> FOAM FATAL ERROR:
face 0 in patch 0 does not have neighbour cell face: 4(0 4 8 9)



I am also open to other suggestions regarding the setting up of two independent inlet boundary condition.

well, you have two options:
1- one patch two profiles (using groovyBC)
2-create two patches:
for creating two patches, you need to define two blocks. It is impossible to divide one face into two patches with one block
