warp.fem.Integrand

class warp.fem.Integrand(func, kernel_options=None)

An integrand is a device function containing arbitrary expressions over Field and Domain variables.

It will get transformed to a proper warp.Function by resolving concrete Field types at call time.

Parameters:

• func (Callable)

• kernel_options (dict[str, Any] | None)

func

Original Python function wrapped by the integrand.

Type:

Callable

name

Fully qualified name of the integrand function.

Type:

str

module

Warp module where the integrand is registered.

Type:

Any

argspec

Full argument specification for the integrand function.

Type:

Any

kernel_options

Kernel options used during kernel generation.

Type:

dict[str, Any]

operators

Resolved operators for field arguments, populated on first integrate call.

Type:

Optional[dict[str, set[“Operator”]]]

cached_kernels

Cache of compiled kernels by specialization key.

Type:

dict[Any, Any]

cached_funcs

Cache of specialized functions by specialization key.

Type:

dict[Any, Any]

__init__(func, kernel_options=None)

Parameters:

• func (Callable)

• kernel_options (dict[str, Any] | None)

Methods

__init__(func[, kernel_options])
