force()

template<class Generator >

template<class T >

void FrictionQPotSpringBlock::detail::SemiSmooth< Generator >::force ( const T & u, T & f )

inline

Update forces based on current slips.

Parameters

template<class T >

double FrictionQPotSpringBlock::detail::SemiSmooth< Generator >::maxUniformDisplacement ( const T & u, int direction ) const

inline

Find maximum particle displacement for which the system is linear and uniform.

Parameters

direction

If +1: move right. If -1 move left.

Returns

Float: particle displacement.

Parameters

u	Slip per particle.
