It is often desirable to replace complex or expensive solid element models with structural elements possessing equivalent mechanical responses. Beam, truss, and spring elements are a few familiar examples, and they can be used in many circumstances. However, the response...
The animation below is a simulation of the flow of water when a dam is broken. The simulation demonstrates the use of the VOF method, which will be available in version 8.1 of ADINA.

In modern earthquake engineering, design for seismic isolation has become increasingly important for the prevention of devastating damage in a major earthquake. One effective and practical method for seismic isolation is the use of friction pendulum bearings, of which many...
The ADINA User Interface (AUI) program offers comprehensive pre- and post-processing capabilities for the complete suite of ADINA Solution programs – Structures, Thermal, CFD, Electromagnetics and Multiphysics. However, other third-party pre- and post-processors can also work with the ADINA solvers...
A shell structure is thin in one direction and long in the other two directions. Shell structures are used in a variety of architectural and industrial applications as they are lightweight, can span large areas, and can be designed to...
The paper “CAE Applications in Hydraulics — Experimental and Analytical Study of a Check-Valve, L. Leventhal, SAE 03NVC-377” contains an interesting application of our fluid-structure interaction code ADINA-FSI. ADINA-FSI is used as the tool in a parametric study of check-valve...
On the launch of ADINA version 9.4 (ADINA 9.4) one year ago, it was announced that the new ADINA sparse solver released in ADINA 9.4 achieves considerable speedups with no compromise in accuracy. This speed increase is of great value...
Shield tunneling using a large tunnel boring machine (TBM) is widely used to construct underground tunnels for subways. During tunneling, the soil strata substance is pressed, crushed, and removed by the TBM boring head. The shields, which are pushed along...
The VOF surface-capturing method, available in ADINA 8.1, can be used to study the motion of bubbles due to buoyant and interfacial forces. The animation below shows the ascension of an air bubble in oil. Both the air and the...
