Member Function Documentation

◆ clear_status()

void NodeLine::clear_status ( )
overridevirtual

Reimplemented from ConditionalModifier.

Here is the call graph for this function:

◆ commit_status()

void NodeLine::commit_status ( )
overridevirtual

Reimplemented from ConditionalModifier.

Here is the call graph for this function:

◆ initialize()

int NodeLine::initialize ( const shared_ptr< DomainBase > &  D)
overridevirtual

Reimplemented from ConditionalModifier.

Here is the call graph for this function:

◆ is_connected()

bool NodeLine::is_connected ( ) const
inlineoverridevirtual

Indicate if this modifier can be deemed as an element that needs to account for connectivity.

Some constraints may modify global stiffness matrix so that it needs to be treated as an element which may affect bandwidth of banded storage. By calling this method, the RCM reordering algorithm will take this constraint into consideration. Make sure it is properly overridden in the derived classes.

Reimplemented from ConditionalModifier.

◆ process()

int NodeLine::process ( const shared_ptr< DomainBase > &  )
overridevirtual

Process and update both stiffness and resistance.

This method provides all necessary pieces of typical constraints/loads required, including additional blocks in original global stiffness, border matrix resistance of multiplier, external loads.

Implements ConditionalModifier.

Here is the call graph for this function:

◆ reset_status()

void NodeLine::reset_status ( )
overridevirtual

Reimplemented from ConditionalModifier.

Here is the call graph for this function:

◆ update_status()

void NodeLine::update_status ( const vec &  i_lambda)
overridevirtual

Reimplemented from ConditionalModifier.
