Linearization of higher order solutions for the purposes of visualization.
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().
Get default function for evaluating physical coordinates given a list of elements and reference element coordinates.
Get default function for evaluating field DOFs given a list of elements and reference element coordinates.
