Detailed Description

Base class for friction constraints (see specialized children classes for more details - this is mostly an interface)

Constructor & Destructor Documentation

chrono::ChLcpConstraintTwoFriction::ChLcpConstraintTwoFriction

(

)

Default constructor.

chrono::ChLcpConstraintTwoFriction::ChLcpConstraintTwoFriction	(	ChLcpVariablesBody *	mvariables_a,
		ChLcpVariablesBody *	mvariables_b
	)

Construct and immediately set references to variables, also setting the and the normal constraint other tangential constraint (the latter is mandatory only for the second of the two tangential constraints)

chrono::ChLcpConstraintTwoFriction::ChLcpConstraintTwoFriction

(

const ChLcpConstraintTwoFriction &

other

)

Copy constructor.

---

Member Function Documentation

ChLcpConstraintTwoFriction& chrono::ChLcpConstraintTwoFriction::operator=

(

const ChLcpConstraintTwoFriction &

other

)

Assignment operator: copy from other object.

virtual bool chrono::ChLcpConstraintTwoFriction::IsLinear

(

)

[virtual]

Tells that this constraint is not linear, that is: it cannot be solved with a plain simplex solver.

Reimplemented from chrono::ChLcpConstraint.

double chrono::ChLcpConstraintTwoFriction::GetFrictionCoefficient

(

)

Get the friction coefficient.

void chrono::ChLcpConstraintTwoFriction::SetFrictionCoefficient

(

double

mcoeff

)

Set the friction coefficient.

double chrono::ChLcpConstraintTwoFriction::Violation

(

double

mc_i

)

[virtual]

The constraint is satisfied?

Reimplemented from chrono::ChLcpConstraint.

void chrono::ChLcpConstraintTwoFriction::StreamIN

(

ChStreamInBinary &

mstream

)

[virtual]

Method to allow deserializing a persistent binary archive (ex: a file) into transient data.

Reimplemented from chrono::ChLcpConstraintTwoBodies.

Reimplemented in chrono::ChLcpConstraintTwoFrictionApprox.

void chrono::ChLcpConstraintTwoFriction::StreamOUT

(

ChStreamOutBinary &

mstream

)

[virtual]

Method to allow serializing transient data into a persistent binary archive (ex: a file).

Reimplemented from chrono::ChLcpConstraintTwoBodies.

Reimplemented in chrono::ChLcpConstraintTwoFrictionApprox.
