Dear Sir,

I want to assign a random distribution of material parameters to the mesh (e.g., porosity and permeability).

I have seen such a mesh in `Tests\Data\Parabolic\ComponentTransport\heterogeneous\ogs5_H_2D`

.

How can I generate such a mesh file?

Thanks

Pavan.

I am using meshio `import meshio`

, then you can use a lines like

```
mesh = meshio.read(inputfile)
mesh.cell_data['vm_permeability'] = [np.array(k_cell)]
```

of course behind the array there must be some logic (even random numbers, since I assume some depth-trend), evaluations of coordinates, interpolation etc.

Dear Dominik,

In case if I need to give a heterogeneous permeability tensor for 2D approximation, do I need to generate a 3x3 tensor or 4x1 vector for simplification?

Because if I need to give `MeshElement`

type permeability, it might result in an error if any tensorial element (xx,yy,zz,xy) is not provided.

Let me know.

Thanks

Pavan

Never mind, I was able to develop the code in Python. Thank you.
