This problem deals with a simulation of diffusion limited aggregation (DLA). The starter code is similar to the solution code from the "Diffusion Limited Aggregation in C and X11" challenge problem linked below.

Your challenge is to modify the starter code found in the "Diffusion Limited Aggregation NetCDF starter zip file" at the bottom of this page, such that the program creates a "dla.nc" file that can be animated in ParaView.

This is a similar task to the "Langton's Ant NetCDF" challenge problem linked below. It may be useful to reference the ParaView instructions and solution code for that problem.
