Notes
Important attributes of continuous (order > 0) Field and
SurfaceField instances:
- vertex_remap : econn[:, :n_vertex] = vertex_remap[conn]
- vertex_remap_i : conn = vertex_remap_i[econn[:, :n_vertex]]
where conn is the mesh vertex connectivity, econn is the
region-local field connectivity.

class sfepy.discrete.fem.fields_nodal.H1DiscontinuousField(name, dtype, shape, region, approx_order=1)[source]
-
average_to_vertices(dofs)[source]
Average DOFs of the discontinuous field into the field region
vertices.
-
extend_dofs(dofs, fill_value=None)[source]
Extend DOFs to the whole domain using the fill_value, or the
smallest value in dofs if fill_value is None.
-
family_name = 'volume_H1_lagrange_discontinuous'
Remove DOFs defined in higher order nodes (order > 1).
-
class sfepy.discrete.fem.fields_nodal.H1NodalMixin(**kwargs)[source]
-
create_basis_context()[source]
Create the context required for evaluating the field basis.
-
set_dofs(fun=0.0, region=None, dpn=None, warn=None)[source]
Set the values of DOFs in a given region using a function of space
coordinates or value fun.
-
class sfepy.discrete.fem.fields_nodal.H1NodalSurfaceField(name, dtype, shape, region, approx_order=1)[source]
A field defined on a surface region.
-
family_name = 'surface_H1_lagrange'
-
interp_v_vals_to_n_vals(vec)[source]
Interpolate a function defined by vertex DOF values using the FE
surface geometry base (P1 or Q1) into the extra nodes, i.e. define the
extra DOF values.
-
class sfepy.discrete.fem.fields_nodal.H1NodalVolumeField(name, dtype, shape, region, approx_order=1)[source]
-
family_name = 'volume_H1_lagrange'
-
interp_v_vals_to_n_vals(vec)[source]
Interpolate a function defined by vertex DOF values using the FE
geometry base (P1 or Q1) into the extra nodes, i.e. define the
extra DOF values.
