Bases: object

2D FE meshing of Monte-Carlo (MCGS) grain structures on a square lattice.

Core mcgs meshing helper for temporal-slice label fields. Non-square lattices should be interpolated to a square grid before use. Supports conformal / non-conformal paths and export-oriented bookkeeping for Abaqus or MOOSE (and related packages).

meshing_package

Backend hint (UPXO / GMSH / PYGMSH).

gb_conformity

Conformal vs non-conformal grain-boundary meshing.

element_type

Finite-element type.

target_fe_software

Destination FE package (e.g. Abaqus, MOOSE).

reduced_integration

Reduced-integration element flag.

Type:

bool

m

Temporal slice identifier.

coords_element_nodes, nodal_connectivity

Node coordinates and element connectivity after meshing.

meshInfo

General mesh metadata.

Type:

dict

ABQ_NODES, ABQ_ELEMENTS

Abaqus-friendly node/element tables when exported.

xgrid, ygrid

Square-lattice coordinate vectors.

lfi

Labelled feature / grain image used as meshing input.

dim

Spatial dimensionality (2 for this class).

elsets, ndsets

Element and nodal set maps for features / boundaries.

mesher_brancher()

Mesher brancher.

abaqus_mesher_brancher()

Abaqus mesher brancher.

upxo_abaqus_nonconformal_mesher()

Upxo abaqus nonconformal mesher.

mesh_abaqus_upxo_nonconformal_quad4()

Generates ABAQUS compatible mesh data-structure inside UPXO targetted at non-conformal mesh with 4 noded quadrilateral elements.

map_elements_grainids()

This makes a map of grain ids and the pixel ids. Map is stored in a dictionary. grain id forms the keys and pixel ids for the values

This is akin to the element-set defined in ABAQUS

abaqus_make_element_sets()

Abaqus make element sets.
