FLUENT - use 64 bit executable for very large problems in serial


Some users may notice that a very large problem will run in parallel over several CPU's, but they cannot allocate enough memory in serial. This may be because 32 bit memory addressing does not provide enough memory locations to handle the size of the problem.
For platforms for which 64 bit addressing is supported by Fluent, it can be invoked at the command line with a "-64" argument.

For example,

fluent 3d -64
