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...
Robustness is an important requirement in nonlinear analysis. One of the requirements of a robust analysis code is that it obtains a realistic solution even with a coarse mesh. In engineering practice, the use of a coarse mesh should lead...
A new meshing feature is present in ADINA 8.1 that enables the user to create a volume mesh from a collection of surface elements making up a closed volume. This is achieved without modifying the surface mesh. This feature is...

The FSI (fluid-structure interaction) solution capabilities of ADINA have been successfully applied to many applications in a wide range of industries over many decades. The ADINA FSI program uses the full capabilities of ADINA CFD and ADINA Structures, with solvers...
The new surface tension option is implemented in the ADINA program, version 8.0. This new option allows the user to assign a surface tension value to selected lines (for 2-D planar and axisymmetric problems) or surfaces (for 3-D problems). The...
The animation shows the three stages of the artery simulation: stretching, uniform blood pressure rise, and several pressure cycles.
