sfepy.discrete.iga.domain module
Computational domain for isogeometric analysis.
-
class sfepy.discrete.iga.domain.IGDomain(name, nurbs, bmesh, regions=None, **kwargs)[source]
Bezier extraction based NURBS domain for isogeometric analysis.
-
static from_data(knots, degrees, cps, weights, cs, conn, bcps, bweights, bconn, regions, name='iga_domain_from_data')[source]
Create the IGA domain from the given data.
-
static from_file(filename)[source]
- filenamestr
The name of the IGA domain file.
-
static read_domain_from_hdf5(fd, group)[source]
Create a domain from the given hdf5 data group.
- fd: tables.File
HDF5 file handle to read the mesh from.
- group: tables.group.Group
HDF5 data group (of file fd) to read the mesh from.
-
write_domain_to_hdf5(fd, group)[source]
Save the domain to a hdf5 file.
- fd: tables.File
HDF5 file handle to write the mesh to.
- group: tables.group.Group
HDF5 data group (of file fd) to write the mesh to.
-
class sfepy.discrete.iga.domain.NurbsPatch(knots, degrees, cps, weights, cs, conn)[source]
Single NURBS patch data.
-
elevate(times=0)[source]
Elevate the patch degrees several times by one.
- Returns:
- nurbsNurbsPatch instance
Either self if times is zero, or a new instance.
-
evaluate(field, u=None, v=None, w=None)[source]
Igakit-like interface for NURBS evaluation.
