Detailed Description
template<class T>
class EBGeometry::SmoothDifferenceIF< T >
class EBGeometry::SmoothDifferenceIF< T >
Implicit function representing a smoothly blended set difference A \ B.
Implemented as a smooth intersection of A with the complement of B. A point is near-inside if it is inside A and outside (or near-outside) B; the interface is smoothed over a region of width m_smoothLen.
- Template Parameters
-
T Floating-point precision.
Constructor & Destructor Documentation
◆ SmoothDifferenceIF() [1/2]
template<class T >
|
noexcept |
Constructs the smooth difference A \ B from two implicit functions.
- Parameters
-
[in] a_implicitFunctionA Minuend (must not be null). [in] a_implicitFunctionB Subtrahend (must not be null). [in] a_smoothLen Smoothing length (must be > 0). [in] a_smoothMax Smooth-maximum operator; defaults to SmoothMax<T>.
◆ SmoothDifferenceIF() [2/2]
template<class T >
|
noexcept |
Constructs the smooth difference A \ union(Bs) from A and a list of subtrahends.
- Parameters
-
[in] a_implicitFunctionA Minuend (must not be null). [in] a_implicitFunctionsB Subtrahends (must be non-empty; no null entries). [in] a_smoothLen Smoothing length (must be > 0). [in] a_smoothMax Smooth-maximum operator; defaults to SmoothMax<T>.
