Running POLYFLOW
– POLYFLOW generates several results files for different purposes once the problem is solved.
– Results file (with res extension by default) • This contains the nodal variables of the unknown fields in ASCII format. This file cannot be used for post-processing ur oses. It is used to restart a calculation from a revious simulation result.
