Visualization of Spectral Element Simulation

 

1. Using IBM Open Visualization Data Explorer (OpenDX)

OpenDX is an application and development software package for visualizing data, especially 3D data from simulations or acquired from observations. It uses a Graphical User Interface based on X windows and Motif.

       In the spectral element simulation, the data is well structured element by element, hence OpenDX is suitable to visualizing the spectral Element simulation of fluids problems. The following is an example:
