Do you have some drawings or sketches

hi @AntonioZJ
You can try using shell elements.
- Import the plan view of your drawing as a background (or simply open it as a new project).
- Draw a polyline over the wall section in the background, or use converted bars directly.
- Download and use ExtrudeLines to create the wall bay (and more) by selecting the polyline.
Here’s the result ↓

Thank you for your answer @Stephane.kapetanovic
I have just one more question.
I want to connect a volumetric object with a shell plate as I show in the picture below and in the attached container model. I think that the mesh is not correct because both element (volumetric and shell) do not have common nodes. I have tried with emitter without success. How can I do this?
Thanks in advance.
hi @AntonioZJ
I don't quite understand the physical design of this joint but to avoid complicating this explanation, you can easily create surfaces on the joint plane from the contours of the upper plates. Once these surfaces are created, extrude them downwards, apply a solid material, recreate your supports, mesh your model.
note that you can also create solid elements by defining the faces that compose it :

Hi again @Stephane.kapetanovic ,
The physical design of this joint is to model the connection of the shipping container shown in the picture below.
This preliminary model ignores the holes in the solid cube (volumetric object).
After this brief clarification, I have one more question. Your solution is valid because the volumetric object (cube) and the shells share the nodes on the edge of the cube, but what is the correct way of solving this other situation?
Now, several shell plates are not coincident with an edge of the cube.
Thanks in advance.
Hi @EduardoMeruvia,
Finally, I have followed your advice and used a cube made up of shells for the corners. The accuracy is enough.
In the picture below, container with maximum load is shown.
However, if the corner were a solid cube, i.e a continious rigid body, I think that model it with shell panels would not be a valid solution. The strains and stresses in a hollow cube (shell plates cube) will be different from those in a solid cube (volumetric object). Do you agree with me?
From the menu in the picture below, I have tried to convert a shell plate cube in a volumetric object but the results do not change. Is it right?
HI @AntonioZJ
for this method to work, the cube must consist of completely closed faces. if the problem of the stress peak lies in the modeling of the supports you must try to bring the edges of the cube plates towards a node support with for example a plate or fictitious elements, rigid connections, etc

Your differentiation of solid vs shell is correct. If the corner cast of the shipping container was a rigid solid, then using shells might not be accurate enough. For this instance you would be better off using a solid element. When combining solids and shells though, just careful on the node compatibility (degrees of freedom at node) between them, see links below for reference.
However, typical shipping container corner cast are hollow cubes which can be represented by simple shell elements, see another typical sample below.
