Topic review (newest first)
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, 3.7.4.1.4 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.
Regards.
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?
Thanks
Giovanni
