Typedef Documentation

◆ Coordsys

typedef ChCoordsys<double> chrono::Coordsys

Shortcut for faster use of typical double-precision coordsys.

Instead of writing "ChCoordsys<double> foo;" you can write the shorter version "Coordsys foo;"

◆ Quaternion

Shortcut for faster use of typical double-precision quaternion.

Instead of writing
   ChQuaternion<double> foo;
or
   ChQuaternion<> foo;
you can use the shorter version
   Quaternion foo;

◆ QuaternionF

Shortcut for faster use of typical single-precision quaternion.

Instead of writing
   ChQuaternion<float> foo;
you can use the shorter version
   Quaternion foo;

◆ Vector

typedef ChVector<double> chrono::Vector

Shortcut for faster use of typical double-precision vectors.

Instead of writing
   ChVector<double> foo;
or
   ChVector<> foo;
you can use the shorter version
   Vector foo;

◆ VectorF

typedef ChVector<float> chrono::VectorF

Shortcut for faster use of typical single-precision vectors.

Instead of writing
   ChVector<float> foo;
you can use the shorter version
   Vector foo;

Enumeration Type Documentation

◆ AngleSet

enum chrono::AngleSet
strong

Definitions of various angle sets for conversions.

Enumerator
EULERO 

sequence: Z - X' - Z''

CARDANO 

sequence: Z - X' - Y''

HPB 

sequence:

RXYZ 

sequence: X - Y' - Z''

◆ ChContactMethod

Enumeration of contact methods.

Enumerator
NSC 

non-smooth, constraint-based (a.k.a. rigid-body) contact

SMC 

smooth, penalty-based (a.k.a. soft-body) contact

◆ eChConstraintMode

Modes for constraint.

Enumerator
CONSTRAINT_FREE 

the constraint does not enforce anything

CONSTRAINT_LOCK 

the constraint enforces c_i=0;

CONSTRAINT_UNILATERAL 

the constraint enforces linear complementarity c_i>=0, l_i>=0, l_1*c_i=0;

CONSTRAINT_FRIC 

the constraint is one of three reactions in friction (cone complementarity problem)

◆ eChUpdateFlags

enum chrono::eChUpdateFlags : unsigned int
strong

Flags to be passed to objects being updated during time stepping.

They are useful for optimizing the computations, and other reasons. In fact it happens that not all update functions require the same 'level of completeness' in recomputing the data in the objects, for example a ChTimestepper might require multiple StateScatter() calls before advancing to the next timestep (for instance in a RungeKutta integrator it takes 4 intermediate StateScatter() calls) but during the intermediate calls there is no need of updating, say, all 3D meshes in visual assets. This is the reason for these flags. They are used by ChIntegrable::StateScatter() by ChPhysicsItem::Update(), and in other parts of the code.

Enumerator
ALL 

Update all data.

NEW_STEP 

This is called when updating at the beginning of a time step.

NO_ASSETS 

Avoid updating visual assets, if any.

NO_COLLISION_SHAPES 

Avoid updating collision shapes, if any.

ChFrameMoving<Real> chrono::operator>> ( const ChFrameMoving< Real > &  Fa,
const ChCoordsys< Real > &  Fb 
)

The '>>' operator that transforms a coordinate system of 'mixed' type: frame_C = frame_A >> frame_B; where frame_A is a ChFrameMoving frame_B is a ChCoordsys Returns a ChFrameMoving.

The effect is like applying the transformation frame_B to frame_A and get frame_C. Also speeds and accelerations are transformed. Performance warning: this operator promotes frame_B to a temporary ChFrameMoving.

template<class Real >
ChFrameMoving<Real> chrono::operator>> ( const ChFrameMoving< Real > &  Fa,
const ChFrame< Real > &  Fb

The '>>' operator that transforms a coordinate system of 'mixed' type: frame_C = frame_A >> frame_B; where frame_A is a ChFrameMoving frame_B is a ChFrame Returns a ChFrameMoving.

The effect is like applying the transformation frame_B to frame_A and get frame_C. Also speeds and accelerations are transformed. Performance warning: this operator promotes frame_B to a temporary ChFrameMoving.

The '>>' operator that transforms 'mixed' types: frame_C = frame_A >> quat_B; where frame_A is a ChFrameMoving frame_B is a ChQuaternion Returns a ChFrameMoving.

The effect is like applying the rotation quat_B to frame_A and get frame_C. Also speeds and accelerations are rotated. Performance warning: this operator promotes quat_A to a temporary ChFrameMoving

template<class Real >
ChFrameMoving<Real> chrono::operator>> ( const ChFrameMoving< Real > &  Fa,
const ChVector< Real > &  Fb 
)

The '>>' operator that transforms 'mixed' types: frame_C = frame_A >> vector_B; where frame_A is a ChFrame frame_B is a ChVector Returns a ChFrameMoving.

The effect is like applying the translation vector_B to frame_A and get frame_C.

◆ operator>>() [11/14]

template<class Real >
ChQuaternion<Real> chrono::operator>> ( const ChQuaternion< Real > &  Fa,
const ChCoordsys< Real > &  Fb

The '>>' operator that transforms 'mixed' types: quat_C = quat_A >> frame_B; where quat_A is a ChQuaternion frame_B is a ChCoordsys Returns a ChQuaternion.

The effect is like applying the transformation frame_B to quat_A and get quat_C.

◆ operator>>() [12/14]

const ChFrame< Real > &  Fb

The '>>' operator that transforms 'mixed' types: quat_C = quat_A >> frame_B; where quat_A is a ChQuaternion frame_B is a ChFrame Returns a ChQuaternion.

The effect is like applying the transformation frame_B to quat_A and get quat_C.

ChVector<Real> chrono::operator>> ( const ChVector< Real > &  Fa,
const ChCoordsys< Real > &  Fb 
)

The '>>' operator that transforms 'mixed' types: vector_C = vector_A >> frame_B; where vector_A is a ChVector frame_B is a ChCoordsys Returns a ChVector.

The effect is like applying the transformation frame_B to frame_A and get frame_C.

◆ operator>>() [14/14]

template<class Real >
ChVector<Real> chrono::operator>> ( const ChVector< Real > &  Fa,
const ChFrame< Real > &  Fb 
)

The '>>' operator that transforms 'mixed' types: vector_C = vector_A >> frame_B; where vector_A is a ChVector frame_B is a ChFrame Returns a ChVector.

The effect is like applying the transformation frame_B to vector_A and get vector_C. For a sequence of transformations, i.e. a chain of coordinate systems, you can also write this (like you would do with a sequence of Denavitt-Hartemberg matrix multiplications, but in the opposite order...) new_v = old_v >> frame3to2 >> frame2to1 >> frame1to0; This operation is not commutative.

◆ Q_from_AngAxis()

ChApi ChQuaternion< double > chrono::Q_from_AngAxis ( double  angle,
const ChVector< double > &  axis 
)

Get the quaternion from an angle of rotation and an axis, defined in abs coords.

The axis is supposed to be fixed, i.e. it is constant during rotation. The 'axis' vector must be normalized.

◆ Q_from_Vect_to_Vect()

ChApi ChQuaternion< double > chrono::Q_from_Vect_to_Vect ( const ChVector< double > &  fr_vect,
const ChVector< double > &  to_vect 
)

Get the quaternion from a source vector and a destination vector which specifies the rotation from one to the other.

The vectors do not need to be normalized.

◆ SetFirstIntID()

ChApi void chrono::SetFirstIntID ( int  val)

Set the start value for the sequence of IDs (ATTENTION: not thread safe) Subsequent calls to GetUniqueIntID() will return val+1, val+2, etc.

The default initial value is 100000.

◆ SetLog()

ChApi void chrono::SetLog ( ChLog new_logobject)

Global function to set another ChLog object as current 'global' logging system.

For example, a plugin developer may like to see logs on a GUI dialog: if so, he can inherit a specialized ChLog class (overriding the Output() function) and use the SetLog() function to have it available all times. Doing so, in your code you can write, for example:

chrono::GetLog() << "message";

◆ StreamSwapBytes()

template<class T >
void chrono::StreamSwapBytes ( T *  ptData)
inline

Templated function for swapping bytes of objects of type 'T', in general fo whatever T type.

This is used for cross-platform compatibility when sharing objects between big-endian and little-endian memory models, depending on the microprocessor type.

◆ swap()

void chrono::swap ( ChAssembly first,
ChAssembly second 
)

Implemented as a friend (as opposed to a member function) so classes with a ChAssembly member can use ADL when implementing their own swap.
