Dear minafogiovanni, please see the ATENA Theory manual for detailed information: 

For the geometry, above all Chapter I.

For the 3D volume elements, 3.5 3D Solid Elements. As far as I understand, hourglassing does not come into question as the linear brick elements have 8 Nodes and also 8 Integration Points.
Under typical conditions, locking is excluded by providing enough elements per thickness in bending direction (see also ATENA 3D User's, Final Notes on Meshing or ATENA-GiD User's, 5.7.1 Notes on Meshing).

If you have some specific suspition, please follow Troubleshooting, 2.1.1 to send us your model etc.



how can be locking and hourglassing checked in a 3D model with IsoBrick elements?
Additionally, what is the formulation adopted by atena3d for geometrically non linear models? Incompatible mode elements?
