foamgen.morphology

Morphology module

synopsis

Create foam morphology in CAD format.

Functions

add_walls(iname, oname, wall_thickness)	Create walls by shrinking each cell.
clean_files()	Delete unnecessary files.
make_walls(fname, wall_thickness, clean, verbose)	Add walls to a tessellated foam.
to_box(iname, oname, ncells, verbose)	Move foam to periodic box.

foamgen.morphology.add_walls(iname, oname, wall_thickness)

Create walls by shrinking each cell.

Uses files in gmsh CAD format.

Parameters

• iname (str) – input filename

• oname (str) – output filename

• wall_thickness (float) – wall thickness parameter

Returns

number of cells

Return type

int

foamgen.morphology.clean_files()

Delete unnecessary files.

foamgen.morphology.make_walls(fname, wall_thickness, clean, verbose)

Add walls to a tessellated foam.

It is assumed that input file uses gmsh built-in kernel. Final geometry is created in the OpenCASCADE kernel.

FileTessellation.geo -> FileWalls.geo -> FileWallsBox.geo -> FileMorphology.geo

Parameters

• fname (str) – base filename

• wall_thickness (float) – wall thickness parameter

• clean (bool) – delete redundant files if True

• verbose (bool) – print additional info to stdout if True

foamgen.morphology.to_box(iname, oname, ncells, verbose)

Move foam to periodic box.

Remove point duplicity, restore OpenCASCADE compatibility, define periodic and physical surfaces.

Parameters

• iname (str) – input filename

• oname (str) – output filename

• ncells (int) – number of cells

• verbose (bool) – print additional info to stdout if True
