class zoomy_core.model.derivative_workflow.StructuredDerivativeModel(init_functions=True, **params)

Bases: Model

Compatibility layer for named fields + derivative mapping.

user_aux_variables = 0

auto_requested_derivatives = False

derivative_canonicalization = 'time_first'

aux_variables()

int([x]) -> integer int(x, base=10) -> integer

Convert a number or string to an integer, or return 0 if no arguments are given. If x is a number, return x.__int__(). For floating point numbers, this truncates towards zero.

If x is not a number or if base is given, then x must be a string, bytes, or bytearray instance representing an integer literal in the given base. The literal can be preceded by ‘+’ or ‘-’ and be surrounded by whitespace. The base defaults to 10. Valid bases are 0 and 2-36. Base 0 means to interpret the base from the string as an integer literal. >>> int(‘0b100’, base=0) 4

requested_derivatives()

Requested derivatives.

Return type:

List[DerivativeSpec]

derivative_buffer_aux_names()

Derivative buffer aux names.

Return type:

List[str]

resolve_field_name(field)

Resolve field name.

Return type:

str

class zoomy_core.model.derivative_workflow.DerivativeAwareSolverMixin

Bases: object

Computes declared derivative buffer entries and fills Qaux.

update_qaux(Q, Qaux, Qold, Qauxold, mesh, model, parameters, time, dt)

Update qaux.

class zoomy_core.model.derivative_workflow.DerivativeAwareSolver(**kwargs)

Bases: DerivativeAwareSolverMixin, HyperbolicSolver

zoomy_core.model.derivative_workflow.print_model_functions(model, function_names=None)

Compatibility wrapper; prefer model.print_model_functions().

Parameters:
