fastElementIPNonlocTableUpdater()

void oofem::NonlocalMaterialWTP::fastElementIPNonlocTableUpdater ( GaussPoint * gp, IntArray & map )

protected

Element plugin for ipEvaluator service to update nonlocal tables of its integration points from given map, containing element dependency.

fastRebuildNonlocalTables()

void oofem::NonlocalMaterialWTP::fastRebuildNonlocalTables ( )

protected

Rebuilds nonlocal integration tables in element gauss points using information in nonlocElementDependencyMap, this should be significantly faster than rebuild the whole information from scratch.

giveNonlocalDepArryElementPlugin()

void oofem::NonlocalMaterialWTP::giveNonlocalDepArryElementPlugin ( GaussPoint * gp, std ::set< int > & s )

protected

Plugin for Element::ipEvaluator service to compile nonlocal dependency array for given element (in case of nonlocal material)

init()

void oofem::NonlocalMaterialWTP::init ( Domain * d )

override

Initializes receiver; should be called before any work transfer. Current implementation assembles for each local element the list of contributing global element numbers. This is extracted from IP nonlocal tables;

migrate()

void oofem::NonlocalMaterialWTP::migrate ( )

override

Migrates necessary local elements to remote processors, where they become remote elements needed to efficiently handle nonlocal dependencies.

This involves several steps:

• send and receive nonlocElementDependencyArry of migrating regular elements to remote partition
• build domain nonlocal element dependency list. Then exclude local elements - what remains are unsatisfied remote dependencies that have to be broadcasted and received from partitions owning relevant elements
• transfer of local elements and nodes to remote partitions (remote elements and null dofmans)
