Benefit from result animation
The BSE software allows users to animate results from different types of analysis such as:
Static linear analysis
Static P-Delta analysis
Buckling analysis
Natural frequencies analysis
Seismic and dynamic analysis

Users can animate various static linear and P-Delta analysis results such as:
Structure displacements
Internal forces
Stresses
Support reactions

Frequency and Buckling
The frequency and buckling analysis provide multiple mode shapes describing multiple behaviors of the structure. With large models, the animation is helpful to discern and understand the mode shapes. It is easier to determine if the buckling mode is a local or global phenomenon. It also provides a very accurate interpretation of the participating mass of each mode in a seismic spectral analysis.

Time-History
The animation function displays every saved time-step to provide an accurate representation of the displacements, velocities, accelerations and internal forces acting on the structure. This will provide users a better understanding of the structure behavior during the dynamic event, such as finding the critical time of the dynamic loading. Animating the envelopes helps minimizing the amount of information on the screen. Users can focus on the most critical regions of the model.
