Simulation of a surface wave (Rayleigh)

This simulation, done in the UCD ESSI simulator and visualized in VisIt using VisIt-ESSI plugin, shows the passage of a surface wave (Rayleigh wave). The simulation consists on a surface impact on an elastic domain of 900m by 1800m depth, and a shear wave velocity of 1000km/s. Elliptical-retrograde motion can be seen as an illustration of Rayleigh waves.

VisIt can be obtained here, and the plugin here.

Visualizing ESSI output with VisIt-ESSI

VisIt-ESSI is a plugin for the VisIt post-processor created my CompGeoMech. It allows for remote (soon parallel also) visualization of outputs produced by ESSI in the HDF5 format (*.h5.feioutput).

VisIt can be obtained here, and the plugin here.

SNE # 01. Example of ESSI simulation and visualization with visitESSI

These are the results of a simple elastic-domain simulation. Mesh consists of

  • 154523 Nodes (46359 DOFs)
  • 1250 27 node bricks (LT formulation)
  • 1200 time-steps (dt = 0.01s)

Results were stored in the new format of output for ESSI simulator and visualized in VisIt post-processor where the movie was created.
