The above animation depicts an axisymmetric model of a mono-tube gas shock absorber, with its schematic beside it. The piston inside the casing pushes its way through the oil (the hydraulic fluid which in reality is a mixture of oil...

FSI (fluid-structure interaction) analysis has many applications in the automotive industry such as the analysis of shock absorbers and valve mechanisms. In the ADINA System, the ADINA-FSI program provides fully coupled analysis of fluid flow with structural interaction problems, meeting...
Nonlinear cyclic symmetry analysis is a new feature in ADINA 8.1 that can be used for static, dynamic and frequency analyses. In static and dynamic analyses, the loads applied to each cyclic part must be identical (when rotated around the...
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...
Rock at depth is subjected to stresses resulting from the weight of the overlying strata and from locked-in stresses of tectonic origin. When an opening is excavated in this rock, the stress field is locally disrupted and a new set...
One interesting feature in the ADINA 8.0 version is the bolt option. A pre-stress beam (pipe) element with a given constant force creates a bolt element. Constant pre-stressing is assured by imposing an initial iteration scheme, during which (under no...
OpenBuildings Designer, Bentley’s multidisciplinary BIM software that aggregates architectural, structural, electrical, and Mechanical design has recently incorporated Hevacomp capabilities. OpenBuildings Energy Simulator – will be available to every OpenBuildings Designer license holder. While Hevacomp workflows can often be segmented, OpenBuildings...
Hydraulic engine mounts are used to reduce automotive engine vibration and noise. The performance of the hydraulic engine mount due to variations in the excitation frequency and amplitude is of interest to the designer.

The animation shows the dynamic analysis of a simplified piping system, similar to those used in nuclear power plants. The analysis is performed using the ADINA subsonic potential-based fluid elements to model the water in the pipe and the ADINA...
