Detailed Description

class paral contains information about local-global ordering

PRIMAL DOMAIN DECOMPOSITION METHOD

nproc, myrank, ndom number of processors, myrank and number of domain are established after constructor execution

ndof, indof total number of local unknowns and number of internal unknowns on subdomains are established after execution of function schurordering

ngdof (M) total number of global unknowns is established after execution of function globcnnum_pdd

maxnbn, maxnrdof, totmaxndofn maximum number of boundary nodes, maximum number of boundary unknowns on subdomain and maximum number of degrees of freedom on node are established after execution of globcnnum_pdd

gcn array of local to global code numbers correspondence is established after execution of function globcnnum_pdd

nbndom (M) array of numbers of boundary nodes on subdomains is established after execution of function globcnnum_pdd

nrdofdom (M) array of numbers of reduced unknowns on subdomains is established after execution of function globcnnum_pdd

masgcn (M) array of local to global code numbers of all subdomains is established after execution of function globcnnum_pdd

FINITE ELEMENT TEARING AND INTERCONNECTING METHOD

nproc, myrank, ndom number of processors, myrank and number of domain are established after constructor execution

ndof total number of local unknowns is established after execution of function schurordering

nbndom (M) array of numbers of boundary nodes on subdomains is established after execution of function globcnnum_feti

maxnbn, totmaxndofn maximum number of boundary nodes and maximum number of degrees of freedom on node are established after execution of globcnnum_feti

nodnum array of legth nbn containing global node numbers; components correspond only to boundary nodes, internal nodes are excluded array is established after execution of function globcnnum_feti

inc, lcngcn array of numbers of incidencies of nodes to subdomains and global code numbers in FETI method are established after execution of function globcnnum_feti

DUAL-PRIMAL FINITE ELEMENT TEARING AND INTERCONNECTING METHOD

totmaxndofn, maxncn, maxncdof, maxnbn maximum number of degrees of freedom on node, maximum number of corner noeds on subdomain, maximum number of corner unknowns on subdomain and maximum number of bounadary nodes on subdomain are established after after execution of function globcnnum_dpfeti

Member Function Documentation

void dpfetiordering ( gtopology * top )

function orders unknowns on subdomain with respect of DP-FETI method unknowns are decomposed into three parts first part contains inner nodes/unknowns second part contains boundary nodes/unknowns except corner nodes/unknowns third part contains corner nodes/unknowns function orders unknowns from two first parts at the beginning unknowns from the third part are ordered at the end nodes are marked with help of ltg array

in the input file ltg[first part]=0 ltg[second part]>0 ltg[third part]<0 before use ltg[first part]=-1 ltg[second part]>-1 ltg[third part]<-1

Parameters:

top

- pointer to topology
