Hello. I am trying to mesh geometry shown in the first picture and abaqus says:

The selected regions cannot be meshed automatically using the assigned element shapes. They must either be partitioned, assigned with a test shape, or manually meshed using the Create Bottom-up Mesh tool.

I tried partitioning, as shown in the second picture, but it still does not allow me to mesh.

Bottom-up mesh is the only option. I use bottom-up mesh separately on these three cuboids. However, the nodes shown in the third picture all have two different node numbers. One is generated when I mesh the left cuboid and the other is generated when I mesh the middle cuboid. The two nodes have almost identical coordinates but they are still separate nodes and this causes issues during the simulation. The fourth picture is an example of the issue.

Could anyone help me with mesh? How can I mesh it so the nodes which connect these cuboids have only one node number? Thanks/
