sfepy.discrete.iga.domain_generators module¶
IGA domain generators.
- sfepy.discrete.iga.domain_generators.create_from_igakit(inurbs, verbose=False)[source]¶
Create
IGDomain
data from a given igakit NURBS object.- Parameters:
- inurbsigakit.nurbs.NURBS instance
The igakit NURBS object.
- Returns:
- nurbsNurbsPatch instance
The NURBS data. The igakit NURBS object is stored as nurbs attribute.
- bmeshStruct instance
The Bezier mesh data.
- regionsdict
The patch surface regions.
- sfepy.discrete.iga.domain_generators.gen_patch_block_domain(dims, shape, centre, degrees, continuity=None, cp_mode='greville', name='block', verbose=True)[source]¶
Generate a single IGA patch block in 2D or 3D of given degrees and continuity using igakit.
- Parameters:
- dimsarray of D floats
Dimensions of the block.
- shapearray of D ints
Numbers of unique knot values along each axis.
- centrearray of D floats
Centre of the block.
- degreesarray of D floats
NURBS degrees along each axis.
- continuityarray of D ints, optional
NURBS continuity along each axis. If None, degrees-1 is used.
- cp_mode‘greville’ or ‘uniform’
The control points mode. The default ‘greville’ results in a uniform Bezier mesh, while the ‘uniform’ mode results in a uniform grid of control points a finer Bezier mesh inside the block and a coarser Bezier mesh near the block boundary.
- namestring
Domain name.
- verbosebool
If True, report progress of the domain generation.
- Returns:
- nurbsNurbsPatch instance
The NURBS data. The igakit NURBS object is stored as nurbs attribute.
- bmeshStruct instance
The Bezier mesh data.
- regionsdict
The patch surface regions.
