sfepy.discrete.iga.utils module¶
Utility functions based on igakit.

sfepy.discrete.iga.utils.
create_linear_fe_mesh
(nurbs, pars=None)[source]¶ Convert a NURBS object into a nD-linear tensor product FE mesh.
Parameters: nurbs : igakit.nurbs.NURBS instance
The NURBS object.
pars : sequence of array, optional
The values of parameters in each parametric dimension. If not given, the values are set so that the resulting mesh has the same number of vertices as the number of control points/basis functions of the NURBS object.
Returns: coors : array
The coordinates of mesh vertices.
conn : array
The vertex connectivity array.
desc : str
The cell kind.

create_mesh_and_output
(nurbs, pars=None, **kwargs)[source]¶ Create a nD-linear tensor product FE mesh using
create_linear_fe_mesh()
, evaluate field variables given as keyword arguments in the mesh vertices and create a dictionary of output data usable by Mesh.write().Parameters: nurbs : igakit.nurbs.NURBS instance
The NURBS object.
pars : sequence of array, optional
The values of parameters in each parametric dimension. If not given, the values are set so that the resulting mesh has the same number of vertices as the number of control points/basis functions of the NURBS object.
**kwargs : kwargs
The field variables as keyword arguments. Their names serve as keys in the output dictionary.
Returns: mesh : Mesh instance
The finite element mesh.
out : dict
The output dictionary.

save_basis
(nurbs, pars)[source]¶ Save a NURBS object basis on a FE mesh corresponding to the given parametrization in VTK files.
Parameters: nurbs : igakit.nurbs.NURBS instance
The NURBS object.
pars : sequence of array, optional
The values of parameters in each parametric dimension.
