Grid Files

Grid files are used in FLAC3D only, for the purpose of constructing zones in one go from an input file.

Inclusion in a Model

There are three principal methods for including a grid file in a model.


when working in PFC, these methods are only available if FLAC3D is loaded (Tools —> Load FLAC3D).


The program supports import of grids from itasca (.f3grid), ansys (.lis), abaqus (.inp), or midas (.csv) formats. The Itasca grid format provides the ability to store group information.
