ANSYS has mesh controls that can provide a similar mesh. There is a mesh control called inflation that will put a layer of small elements around (or along) a boundary.
If you create the geometry and attach it to your reply, I can show you these mesh controls.

Peter is right about the inflation layer. Attached is a workbench archive file which shows two different ways of meshing the geometry.
Refer to the pictures below. The first one is similar to the one you needed help with and the second one is a very easy way of meshing the geometry without any modification to the geometry but with inflation around the holes.

You can also use the Cut Cell method to apply a hexahedral mesh. I think ANSYS meshing tool would usually impose a hexa-dominant mesh for simple geometries like this one.

Can you attach a Ansys 18.2 file?The beam and the end-plate have different materials (A572 and A36). So I do not know how I match the node between different bodies with bonded contact.

Raef, the Cut Cell method is only to CFD analyse, isn't it?

Raul, I reached a good mesh dividing the edges and some faces. So the geometry is simpler. And I think that it is not necessary to use "node merge" between the contact, I asked it for Peter, He said it. And results are becoming better. See what happen if I use the node merge.
What do you think about the mesh, In this exactly moment I am doing the convergence test, saving four or five model, increasing the number of nodes and mesh quality.
Thank you very much!!!!

I would divide the face on the base plate along the three planes of the beam that you want to represent as welded to the base plate, then use Node Merge. On other models, I have even created triangular solids to represent the weld bead and bonded that extra material to the model.

Fabricio, node merge is important if you want a conformal mesh between the bodies. Without node merge the nodes of the bodies are free to move. Although they might appear conformal with uniform setting of "Multizone", they won't have conformity unless you use node merge. Again the requirement depends on what you're trying to model.

I will try it, divide the base plate along the three planes. Yes, I thought about modelling the weld, but for this master thesis I will not do it yet.
Thank you again!!!
