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

virtual

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;

void oofem::NonlocalMaterialWTP::migrate ( )

virtual

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)
