Reciprocal Space X-Ray Diffraction

Simulation of diffraction in alumina. Visualization occurs in reciprocal space. This project integrated automatic generation of imagery using VisIt into the GridChem Computational Chemistry Grid. CCG users upload a VisIt sessionfile along with their simulation input and get back images with their usual output.

The project was featured in the NCSA Access story: A Direct Bridge.

The collaboration won two awards at XSEDE14: Best Software and Software Environments Paper and Best Overall Paper, for the submission:
