ffc.uflacs.backends.ufc.evaluatebasis module

Work in progress translation of FFC evaluatebasis code to uflacs CNodes format.

ffc.uflacs.backends.ufc.evaluatebasis.generate_evaluate_reference_basis(L, data)

Generate code to evaluate element basisfunctions at an arbitrary point on the reference element.

The value(s) of the basisfunction is/are computed as in FIAT as the dot product of the coefficients (computed at compile time) and basisvalues which are dependent on the coordinate and thus have to be computed at run time.

The function should work for all elements supported by FIAT, but it remains untested for tensor valued elements.

This code is adapted from code in FFC which computed the basis from physical coordinates, and also to use UFLACS utilities.

The FFC code has a comment “From FIAT_NEW.polynomial_set.tabulate()”.

ffc.uflacs.backends.ufc.form module

ffc.uflacs.backends.ufc.form.add_ufc_form_integral_methods(cls)

This function generates methods on the class it decorates, for each integral name template and for each integral type.

This allows implementing e.g. create_###_integrals once in the decorated class as ‘_create_foo_integrals’, and this function will expand that implementation into ‘create_cell_integrals’, ‘create_exterior_facet_integrals’, etc.

Name templates are taken from ‘integral_name_templates’ and ‘ufc_integral_types’.
