Hi I am beginner for CFD and OpenFOAM

I am very curious the possibility of using unstructured Cartesian meshes (as shown in the picture) in OpenFOAM

what software should I use to generate this type mesh???

Hello Eric,
you can create unstructured grids using gmesh. A structure as shown in your post can be created by OpenFOAM if you snappyHexMesh and a suitable stl. file to generate the mesh.
