Download movie as MP4 or WebM.

The image depicts a horse's silhouette, with color gradations indicating varying levels of intensity in the image. The colors range from red (indicating high intensity) to blue (indicating low intensity). This is likely an animation or movie still showing how pressure waves travel through the body of the horse during a simulation.

LS-DYNA is a software package for nonlinear dynamic finite element analysis of structures, solids, systems, and materials. It can be used to simulate complex physical phenomena such as explosions, crashes, and other events that involve large deformations, damage, and failure. The program uses a combination of numerical methods, including the finite element method, to model the behavior of materials and structures under various loads.

The simulation "horsem/mp4movies1/movie_0125.mp4" is likely a dynamic simulation of a horse's body responding to an external force or load. The color gradations in the image suggest that the simulation is analyzing how pressure waves propagate through the horse's body, which could be useful for understanding how different materials respond to impacts or other types of loading.

Overall, the image provides a visual representation of the results of a dynamic simulation using LS-DYNA software, highlighting the complex behavior of the horse's body under various loads.
