Member Function Documentation

◆ assemble_matrix()

void BatheTwoStep::assemble_matrix ( )

overridevirtual

Assemble the global effective matrix A in AX=B. For FEM applications, it is often a linear combination of stiffness, mass, damping and geometry matrices.

Reimplemented from Integrator.

Here is the call graph for this function:

◆ assemble_resistance()

void BatheTwoStep::assemble_resistance ( )

overridevirtual

Reimplemented from Integrator.

Here is the call graph for this function:

◆ clear_status()

void BatheTwoStep::clear_status ( )

overridevirtual

Reimplemented from Integrator.

Here is the call graph for this function:

◆ commit_status()

void BatheTwoStep::commit_status ( )

overridevirtual

Reimplemented from Integrator.

Here is the call graph for this function:

◆ from_incre_acceleration()

vec BatheTwoStep::from_incre_acceleration	(	const vec &	,
		const uvec &	encoding
	)

overridevirtual

When external loads are applied, they can be applied in forms of displacement/velocity/acceleration. The time integration methods, by default, form effective stiffness matrices in displacement domain. That is, in AX=B, A is the effective stiffness matrix and X is the displacement increment. Thus, loads in velocity/acceleration must be converted to displacement. This cannot be done arbitrarily due to compatibility issues. This method takes acceleration increment and converts it to TOTAL displacement.

Reimplemented from Integrator.

Here is the call graph for this function:

◆ from_incre_velocity()

vec BatheTwoStep::from_incre_velocity	(	const vec &	,
		const uvec &	encoding
	)
