DESCRIPTION
The Surface Evolver is a program that minimizes the energy of a triangulated surface according to designated energies and constraints. This man page only documents command line options and environment variables. The full package and documentation are available at http://www.susqu.edu/brakke/evolver.

Command line options:

datafile
    Text file defining a surface. If omitted, you will be prompted.

-m  Begin with memory debugging on (equivalent to "memdebug" runtime command). Beware of copious output.

-pN Run with N concurrent processes.

-q  Convert to named quantities at start (equivalent to "convert_to_quantities" runtime command).

-Q  Suppress echoing of "read" section of datafile, and other files read in.

-w  Exit immediately after any warning or error message; meant for batch runs.

-x  Exit immediately after any error message; meant for batch runs.
