sfepy.discrete.fem.linearizer module

Linearization of higher order solutions for the purposes of visualization.

sfepy.discrete.fem.linearizer.create_output(eval_dofs, eval_coors, n_el, ps, min_level=0, max_level=2, eps=0.0001)

Create mesh with linear elements that approximates DOFs returned by eval_dofs() corresponding to a higher order approximation with a relative precision given by eps. The DOFs are evaluated in physical coordinates returned by eval_coors().

sfepy.discrete.fem.linearizer.get_eval_coors(coors, conn, ps)

Get default function for evaluating physical coordinates given a list of elements and reference element coordinates.

sfepy.discrete.fem.linearizer.get_eval_dofs(dofs, dof_conn, ps, ori=None)

Get default function for evaluating field DOFs given a list of elements and reference element coordinates.
